Many needs in the construction industry such as lifting need different solutions. Such works are very dangerous and they need care and precision in their lifting. The machines used must have the height factor and strong too at the same time. Cranes consist of a hoist, ropes or wires and a winding drums if not hydraulics are put into use. Below are some of types of crane rentals Vancouver Island and their uses.

An overhead crane is a machine that moves along a horizontal raised rail thus the name overhead. It has mobility along the railings overhead however; it is limited to the length of the rails. It usually is mostly used in industries where small loads that could be heavy for human lifting or touching. It ranges from small capacity to maximum loading needed and what the rails can hold.

A truck mounted machine is a hoist mounted on a moving truck. This truck is able to provide mobility to the lifting machine. The hoist is referred to as the boom and the truck is known as the carrier. They are joined together at a place called a turntable which adds the swivel movements to boom. This offers more mobility and they can be used in almost any position and place since they can be driven to the location.

The crawler crane is a machine mounted on a carrier that has conveyor or crawlers. The crawlers are used to provide the short need movements during the lifting exercised thus increases the precision. The crawlers can be used on soft ground where the other cranes would sink and loose stability that is the main cause of toppling over. It also does not sink because it has a broad surface area thanks to the broad and long conveyors.

A floating machine is a machine that is mounted on a pontoons or barges that can float on water. They are used on ship construction and bridges. They might be used in under water construction like oil rigs. They can also be used to salvage sunken from the ocean floors since they can float.

There are cranes fitted in helicopters. They almost work as overhead cranes but they have more degree of movement thus can do a wide variety of lifting. It can be used to access remote and inaccessible areas where other cranes cannot access. It normally is used mostly for rescue purposes and in the army.

A tower cranes is lifting equipment used in the construction of tall buildings and skyscrapers. It works on balancing mechanisms where it is fixed on the ground on a concrete slab. Then a horizontal arm is attached with a driving mechanism geared to control the movement. It provides both the lifting load capacity and height.

A telescopic crane is the lifting machine that has a boom which retracts. It normally is controlled and powered by hydraulics. They can adjust its length by elongating or retracting the boom. It is used in short term constructions or rescue mission that need the long arm length.
