Unlike other types of cranes on construction sites, hydraulic truck cranes are heavy equipment that relies on internal hydraulic systems to lift and lift heavy objects. They are mounted on wheels, making them more maneuverable on the job site. Hydraulic truck cranes usually have a closed operator cab, mounted on a steel base, and a long telescopic boom that can be articulated or fixed, depending on the specific construction requirements of each project.
Other important parts of hydraulic truck crane are:
Cantilever or pulley-this is a lattice structure that extends the length of the telescopic boom.
These are telescopic supports that provide crane stability and balance by increasing its overall footprint.
Counterweight-These weights keep the machine stable during the lifting process. They are placed on the back of the cab to further reduce the risk of crane overturning.
Load movement indicator-This is a safety device with sensors to prevent overload. In order to avoid crane failures and accidents, it lets the operator know when the maximum lifting capacity is reached.
Rotex gear-This element allows the operator to move accurately left and right during the lifting process. It is usually controlled by the joystick controller in the operator’s cab.
Steel cable-this piece runs across the boom and helps to hold the load with a hook. It is usually connected with lable, the cable passes through the baffle, and is fixed to the ball or clock according to the weight of the load.
The dual gear pump is connected to hydraulic pistons, pipes, and hoses. Regardless of the weight, it will apply pressure to the required hydraulic fluid to generate enough power to increase the load.
Ensure that your operators receive safety training before being allowed to handle this or other heavy equipment at the construction site. Insufficient training can lead to large-scale injuries and injuries.
How does a hydraulic truck crane work?
The hydraulic system of a crane uses pressurized fluid (usually oil) to generate all the lifting power required to obtain a large load. The hydraulic truck crane uses a fixed pipe system that allows the operator to maintain a constant pressure when lifting.
These lifting equipment are very stable. The pump usually generates pressure, moves two different pistons, and helps transfer force by moving the oil. Most hydraulic truck cranes on the market have two types of pumps:
Gear pump-this variety consists of interlocking gears. When the operator increases the engine speed, these gears will replace the hydraulic oil. It is the standard pump system for most low-cost models. The only way to get high pressure with a gear pump is to run the engine at full power.
Variable pump-this type is more complicated. It consists of multiple piston cylinders connected to a ring and a swashplate in the barrel. In order to generate enough pressure, the barrel begins to rotate, and the swash plate pushes and pulls the piston in and out of the cylinder, drawing oil into the hydraulic system.
Both types can provide enough power for the crane to increase the load. They allow these hydraulic truck cranes to easily lift thousands of pounds. The design of these lifting equipment may seem simple, but their performance is better than most other cranes on the construction site.
