Popular Crane Renting Terms
Heavy duty construction equipment is used in all sorts of different settings, including construction sites, factories and oil rigs. While some companies own a fleet of machines and vehicles, others will need to rent specific pieces for a particular project. Renting equipment may offer certain advantages, including saving on repairs and maintenance fees. The material handling machines that may be rented for a construction project or on an oil rig include cranes, dumpers and loaders. These machines are responsible for hoisting heavy objects, demolishing structures, moving earth and transporting materials. These vehicles often feature hydraulic parts that provide them with additional power.
Gantry - Gantry cranes are used to move heavy objects and lift loads on a construction site.
Forklift - A forklift is an industrial vehicle that moves and hauls materials on pallets. These are used on both construction locations and factories.
Overhead - An overhead crane is used to move and hoist beams to assemble structures.
Mobile - Mobile cranes are easily transported to a construction site and can be used to demolish a building or excavate earth.
Excavators - Excavators have a variety of uses on a site. These vehicles can perform excavating and hauling duties.
Telescopic - A telescopic crane features a hydraulic system that extends and retracts a boom that is used to demolish buildings.
Tower - Tower cranes have a high lifting capacity and are commonly used in the construction of skyscrapers and other tall buildings.
Scissor Lift - A scissor lift is used to reach a specific height when working on a project.
Most cranes that are used on construction sites come from rental companies. Very few companies are large enough to purchase their own hoisting equipment. Renting cranes reduces overhead and also the risk of a company being left to maintain unneeded equipment during a slow time.
The majority of cranes are mobile. Cranes are mounted to truck chassis or to large all terrain vehicles. They are driven much like big rigs, by commercial drivers. Giant port cranes, however, may remain in the same position on the docks for years. Their relocation requires special equipment and knowledge. Large tower cranes are towed to construction and work sites by special vehicles. There are also small rigging cranes and camera cranes, which are commonly battery operated. Forklift trucks are generally small, but also fall into the category of hoists and lifts.
The truck crane is the most common crane, being attached to a modified truck. Crawler cranes, on the other hand, have a chassis with tracks, similar to a tank. Cranes are generally hired with their operators and driven to the site or plant. Most cranes work on a hydraulic principle, with what is called a telescopic boom. This means that the boom's length can be adjusted. There are also scissor lifts, which have supports that concertina. Overhead cranes, which are fixed in warehouses, can carry heavy weights on tracks that are supported below the ceiling. Cargo ships commonly have small deck cranes which are also stationary and fixed. These cranes tend to be bought more often than rented and are seldom moved.
Crane rental companies are often also involved in heavy hauling. They may also rent other equipment, such as backhoes and large trucks.
