Topics Why wooden boats? Why Wooden Boats? The creation of beauty is more satisfying and joyous than mere possession. For the person who loves boats, and has time on his hands, what better way to spend some of it than to build himself a boat that will please him every time he looks at it or uses it.

It will take some pains, both in the figurative and the literal sense, for the creative process at levels of excellence is never easy, and often its demands are rigorous and its discipline severe. Any man who wants to can produce a good boat. It takes some study, some practice, and, of course, experience.

The experience starts coming the minute you begin, and not one jot. As one of my builder friends says, Its only a boat; go ahead and build it. If the first effort is a bit lumpy, so what?

There will be another much less lumpy later on. Pete Wood boat construction methods 20, Wooden Boats, p. But What Kind of Wood? Spars mast, boom, Light, strong, long length.

In older model designs of hydraulic truck cranes, there were two engines. One in the lower pulled the crane down the road and ran a hydraulic pump for the outriggers and jacks. The one in the upper ran the upper through a hydraulic pump of its own. Many older operators favor the two-engine system due to leaking seals in the turntable of aging newer design cranes.

Hiab invented the world's first hydraulic truck mounted crane in Generally, these cranes are able to travel on highways, eliminating the need for special equipment to transport the crane unless weight or other size constrictions are in place such as local laws.

If this is the case, most larger cranes are equipped with either special trailers to help spread the load over more axles or are able to disassemble to meet requirements. An example is counterweights. Often a crane will be followed by another truck hauling the counterweights that are removed for travel.

In addition some cranes are able to remove the entire upper. However, this is usually only an issue in a large crane and mostly done with a conventional crane such as a Link-Belt HC When working on the job site, outriggers are extended horizontally from the chassis then vertically to level and stabilize the crane while stationary and hoisting. Many truck cranes have slow-travelling capability a few miles per hour while suspending a load.

Great care must be taken not to swing the load sideways from the direction of travel, as most anti-tipping stability then lies in the stiffness of the chassis suspension. Most cranes of this type also have moving counterweights for stabilization beyond that provided by the outriggers.

Loads suspended directly aft are the most stable, since most of the weight of the crane acts as a counterweight. Factory-calculated charts or electronic safeguards are used by crane operators to determine the maximum safe loads for stationary outriggered work as well as on-rubber loads and travelling speeds. Truck cranes range in lifting capacity from about A rough terrain crane has a boom mounted on an undercarriage atop four rubber tires that is designed for off-road pick-and-carry operations.

Outriggers are used to level and stabilize the crane for hoisting. These telescopic cranes are single-engine machines, with the same engine powering the undercarriage and the crane, similar to a crawler crane.

The engine is usually mounted in the undercarriage rather than in the upper, as with crawler crane. Most have 4 wheel drive and 4 wheel steering for traversing tighter and slicker terrain than a standard truck crane, with less site prep. A crawler crane has its boom mounted on an undercarriage fitted with a set of crawler tracks that provide both stability and mobility. Crawler cranes range in lifting capacity from about 40 to 4, long tons The main advantage of a crawler crane is its ready mobility and use, since the crane is able to operate on sites with minimal improvement and stable on its tracks without outriggers.

Wide tracks spread the weight out over a great area and are far better than wheels at traversing soft ground without sinking in. A crawler crane is also capable of traveling with a load. Its main disadvantage is its weight, making it difficult and expensive to transport.

Typically a large crawler must be disassembled at least into boom and cab and moved by trucks, rail cars or ships to its next location. Floating cranes are used mainly in bridge building and port construction, but they are also used for occasional loading and unloading of especially heavy or awkward loads on and off ships. Some floating cranes are mounted on pontoons , others are specialized crane barges with a lifting capacity exceeding 10, short tons 8, long tons ; 9, t and have been used to transport entire bridge sections.

Floating cranes have also been used to salvage sunken ships. Crane vessels are often used in offshore construction. The largest revolving cranes can be found on SSCV Thialf , which has two cranes with a capacity of 7, tonnes 7, short tons ; 6, long tons each. For 50 years, the largest such crane was " Herman the German " at the Long Beach Naval Shipyard , one of three constructed by Nazi Germany and captured in the war.

The crane was sold to the Panama Canal in where it is now known as Titan. An all-terrain crane is a hybrid combining the roadability of a truck-mounted and on-site maneuverability of a rough-terrain crane. It can both travel at speed on public roads and maneuver on rough terrain at the job site using all-wheel and crab steering.

AT's have 2�12 axles and are designed for lifting loads up to 2, tonnes 2, short tons ; 1, long tons. A pick and carry crane is similar to a mobile crane in that is designed to travel on public roads; however, pick and carry cranes have no stabiliser legs or outriggers and are designed to lift the load and carry it to its destination, within a small radius, then be able to drive to the next job.

Pick and carry cranes are popular in Australia, where large distances are encountered between job sites. One popular manufacturer in Australia was Franna, who have since been bought by Terex, and now all pick and carry cranes are commonly called "Frannas", even though they may be made by other manufacturers. Nearly every medium- and large-sized crane company in Australia has at least one and many companies have fleets of these cranes.

The capacity range is between ten and forty tonnes as a maximum lift, although this is much less as the load gets further from the front of the crane. Pick and carry cranes have displaced the work usually completed by smaller truck cranes, as the set-up time is much quicker. Many steel fabrication yards also use pick and carry cranes, as they can "walk" with fabricated steel sections and place these where required with relative ease.

A sidelifter crane is a road-going truck or semi-trailer , able to hoist and transport ISO standard containers. Container lift is done with parallel crane-like hoists, which can lift a container from the ground or from a railway vehicle. A carry deck crane is a small 4 wheel crane with a degree rotating boom placed right in the centre and an operators cab located at one end under this boom.

The rear section houses the engine and the area above the wheels is a flat deck. Very much an American invention the Carry deck can hoist a load in a confined space and then load it on the deck space around the cab or engine and subsequently move to another site.

The Carry Deck principle is the American version of the pick and carry crane and both allow the load to be moved by the crane over short distances. Telescopic handlers are forklift -like trucks that have set of forks mounted on a telescoping extendable boom like a crane. Early telescopic handlers only lifted in one direction and did not rotate; [54] however, several of the manufacturers have designed telescopic handlers that rotate degrees through a turntable and these machines look almost identical to the Rough Terrain Crane.

These machines are often used to handle pallets of bricks and install frame trusses on many new building sites and they have eroded much of the work for small telescopic truck cranes. Many of the world's armed forces have purchased telescopic handlers and some of these are the much more expensive fully rotating types.

Their off-road capability and their on site versatility to unload pallets using forks, or lift like a crane make them a valuable piece of machinery. A travel lift also called a boat gantry crane, or boat crane is a crane with two rectangular side panels joined by a single spanning beam at the top of one end.

The crane is mobile with four groups of wheels steerable wheels, one on each corner. These cranes allow boats with masts or tall super structures to be removed from the water and transported around docks or marinas. A railroad crane has flanged wheels for use on railroads.

The simplest form is a crane mounted on a flatcar. More capable devices are purpose-built. Different types of crane are used for maintenance work , recovery operations and freight loading in goods yards and scrap handling facilities.

Aerial cranes or "sky cranes" usually are helicopters designed to lift large loads. Helicopters are able to travel to and lift in areas that are difficult to reach by conventional cranes. Helicopter cranes are most commonly used to lift loads onto shopping centers and high-rise buildings.

They can lift anything within their lifting capacity, such as air conditioning units, cars, boats, swimming pools, etc.

They also perform disaster relief after natural disasters for clean-up, and during wild-fires they are able to carry huge buckets of water to extinguish fires. Some aerial cranes, mostly concepts, have also used lighter-than air aircraft, such as airships. Exchanging mobility for the ability to carry greater loads and reach greater heights due to increased stability, these types of cranes are characterised by the fact that their main structure does not move during the period of use.

However, many can still be assembled and disassembled. The structures basically are fixed in one place. Ring cranes are some of the largest and heaviest land-based cranes ever designed. A ring-shaped track support the main superstructure allowing for extremely heavy loads up to thousands of tonnes. Tower cranes are a modern form of balance crane that consist of the same basic parts.

Fixed to the ground on a concrete slab and sometimes attached to the sides of structures , tower cranes often give the best combination of height and lifting capacity and are used in the construction of tall buildings. The base is then attached to the mast which gives the crane its height. Further, the mast is attached to the slewing unit gear and motor that allows the crane to rotate.

On top of the slewing unit there are three main parts which are: the long horizontal jib working arm , shorter counter-jib, and the operator's cab. Optimization of tower crane location in the construction sites has an important effect on material transportation costs of a project.

The long horizontal jib is the part of the crane that carries the load. The counter-jib carries a counterweight, usually of concrete blocks, while the jib suspends the load to and from the center of the crane. The crane operator either sits in a cab at the top of the tower or controls the crane by radio remote control from the ground. In the first case the operator's cab is most usually located at the top of the tower attached to the turntable, but can be mounted on the jib, or partway down the tower.

The lifting hook is operated by the crane operator using electric motors to manipulate wire rope cables through a system of sheaves. The hook is located on the long horizontal arm to lift the load which also contains its motor. In order to hook and unhook the loads, the operator usually works in conjunction with a signaller known as a "dogger", "rigger" or "swamper". They are most often in radio contact, and always use hand signals. The rigger or dogger directs the schedule of lifts for the crane, and is responsible for the safety of the rigging and loads.

Tower cranes can achieve a height under hook of over metres. Tower cranes are used extensively in construction and other industry to hoist and move materials. There are many types of tower cranes. Although they are different in type, the main parts are the same, as follows:.

A tower crane is usually assembled by a telescopic jib mobile crane of greater reach also see "self-erecting crane" below and in the case of tower cranes that have risen while constructing very tall skyscrapers, a smaller crane or derrick will often be lifted to the roof of the completed tower to dismantle the tower crane afterwards, which may be more difficult than the installation.

Tower cranes can be operated by remote control, removing the need for the crane operator sit in a cab atop the crane. Each model and distinctive style of tower crane has a predetermined lifting chart that can be applied to any radii available, depending on its configuration. Similar to a mobile crane, a tower crane may lift an object of far greater mass closer to its center of rotation than at its maximum radius.

An operator manipulates several levers and pedals to control each function of the crane. When a tower crane is used in close proximity to buildings, roads, power lines, or other tower cranes, a tower crane anti-collision system is used. This operator support system reduces the risk of a dangerous interaction occurring between a tower crane and another structure.

In some countries, such as France, tower crane anti-collision systems are mandatory. Generally a type of pedestrian operated tower crane. Self-erecting tower cranes are transported as a single unit and can be assembled by a qualified technician without the assistance of a larger mobile crane. They are bottom slewing cranes that stand on outriggers, have no counter jib, have their counterweights and ballast at the base of the mast, cannot climb themselves, have a reduced capacity compared to standard tower cranes, and seldom have an operator's cabin.

In some cases, smaller self-erecting tower cranes may have axles permanently fitted to the tower section to make maneuvering the crane onsite easier.

Tower cranes can also use a hydraulic-powered jack frame to raise themselves to add new tower sections without any additional other cranes assisting beyond the initial assembly stage.

This is how it can grow to nearly any height needed to build the tallest skyscrapers when tied to a building as the building rises. The maximum unsupported height of a tower crane is around ft. A telescopic crane has a boom that consists of a number of tubes fitted one inside the other. A hydraulic cylinder or other powered mechanism extends or retracts the tubes to increase or decrease the total length of the boom. These types of booms are often used for short term construction projects, rescue jobs, lifting boats in and out of the water, etc.

The relative compactness of telescopic booms makes them adaptable for many mobile applications. A telescopic tower crane has a telescopic mast and often a superstructure jib on top so that it functions as a tower crane.

Not only are they wonderful to look at and a pleasure to build, they also perform quite well. This construction method permits a clean, sharp entry and a subtle shape that is difficult to achieve with aluminum or fiberglass.

The century-old technology of clenching thin planks to steamed frames and then covering the hull with a tight canvas skin yields an amazingly flexible and rugged craft. And the ingenious forms developed years ago by companies like Old Town and E. White make the building process relatively quick and easy. Rollin Thurlow has been building and using, writing and teaching about wood-and-canvas canoes for years.

You'll start by steam-bending the clear cedar ribs onto the two forms. Wood that is dried below 20 percent moisture content is not susceptible to decay or sap staining. To reduce the. Methods of Natural Seasoning of Wood The basic principle is to stack the timber so that plenty of air can circulate around each piece. The timber is stacked with wide spaces between each piece horizontally, and with strips of wood between each layer ensuring that there is a vertical separation too.

Air can then circulate around and through the stack, to slowly remove moisture. In some cases, weights can be placed. Wood , Wood Seasoning , Materials Engineering. In addition, fire annually causes widespread destruction of wood structures. Decay will not occur if wood is kept well ventilated and air-dry or. Chemical Seasoning and Preservatives of Wood There are 3 main classes of preservatives Oily substances insoluble in water Water-soluble salts Salts carried in volatile solvent other than water.

Artificial Methods of Wood and Timber Seasoning Kiln drying of lumber is perhaps the most effective and economical method available. Where staining is a problem, kiln drying is often the only reasonable. Search AboutCivil. Training Course.
