How does boom truck crane work?

A boom truck crane is a mobile crane with a telescoping boom with the ability to lift tons of weight. Unlike many of the small static cranes, which rely on diesel-powered or electric motors, the hydraulic cranes make use of pressurized oil to operate. Most of the large cranes have a lift capacity in the region of 50 to 300 tons.

The use of hydraulic crane trucks is essential for large-scale construction projects, including those related to roadworks, airports, large buildings, and bridges.

How it Works

This type of crane truck is significantly different to most other types of heavy lifting devices. Rather than using the old-fashioned winch and cable to give the desired lift force, the modern hydraulic cranes make use of pressurized oil. This type of fluid has the ability to retain its original volume. Oil is an incompressible fluid and a highly reliable option to push the cranes pistons in the right direction to create enough force and power to make it possible to lift heavy loads.

The actual part of the crane involved in lifting is the large arm-like structure known as the boom. The boom can extend to various lengths depending on the size of the truck. Many of the main booms have the potential to extend to a length of 115 to 225 feet. Plus, when the boom isn’t in use it fully retracts to make it easier to relocate from job to job. To make the hydraulic crane truck easy to relocate it is built to be fully mobile with minimal dismantling required at each job site. Also, the vehicle is built to operate on a single engine to control both the crane and truck.

To avoid tipping the crane vehicle when the boom is at full reach, it is designed with a counterweight system to take into account the extra weight of lifting heavy loads. A reliable counterweight system has the ability to provide about 1,400-pounds per square inch. For greater versatility in operation the boom is designed to operate freely with the ability to move left and right as well as up and down.

Other parts

The hydraulic crane truck comes with a variety of safety and practical components to make sure it is easy to use. Outriggers are an essential part of the crane to give a stable platform when the truck is working the hydraulics. Its boom elevation is achieved using twin hydraulic cylinders that are easily lowered and raised. Plus, the rotex gear is there to help the boom swivel in the right direction and usually located beneath the cab.

There are also concrete boom trucks. The booms on these types of vehicles contain a pipe with a nozzle at the far end, and are used to pump concrete and other materials into specified areas. These areas are, in most cases, inaccessible to the vehicle, or are at a considerable height. The boom on a larger concrete boom truck may be extended some 230 feet (71 m). Material is then pumped from the vehicle through the extended boom and directly into the space where it is needed.

Many fire departments are equipped with a fairly lengthy bucket boom to raise firefighters to the upper levels of a building. From there, they may direct water onto the flames, or they may be used to rescue trapped victims. Boom trucks are often a replacement for, or an adjunct to, many of the older hook-and-ladder trucks.
