How does a telescopic boom work?
When a load is placed on a telescopic boom, the load weight on the boom causes the hydraulic rams within the boom to stiffen up and slightly curve. As the load is removed from the boom, the rams return straight. Because of this, do not extend the boom while it is under load.
What is a telescopic boom crane?
Telescopic truck-mounted cranes, also known as boom trucks, are used to lift materials by use of a hydraulic winch and by raising and lowering the boom. Operation is simple enough: rotate, extend, and raise and lower as necessary.
How do extendable cranes work?
Crane booms work on forces of leverage. The further the boom extends, the less weight the boom can lift as the truck can easily tip, so a lot of engineering goes into each lift. Attached to the end of the boom is a hook, or hoist, that also extends down and attaches to the load or materials that will be lifted.
How does a telehandler boom extend?
Boom extend – This is done with a long double-acting cylinder with counterbalance valves built in. The extension is typically multiplied by a chain mechanism. Hoist and forks – This is almost always done with proportionally controlled, double-acting cylinders, with counterbalance valves built into the hoist cylinders.
How wide is a boom lift?

Which two cranes typically use a lattice boom?
There are three types of lattice boom cranes.
- The crawler crane has the advantage of moving with loads for a short distance. Its maximum capacity is 1.600T.
- The outrigger crane consists of the pedestal crane and the truck crane.
- The third type is the ring crane.
What is a telescopic crane used for?
Telescopic cranes are a form of heavy cranes employed to transport objects. Cranes like the telescopic cranes are often used in day-to-day hauling operations but it has also to be noted that these heavy cranes are very important when it comes to carrying out manoeuvring operations in shipping ports.
How long does a telehandler last?
In more normal applications it could be 7,000 to 10,000 hours. It really depends on a number of things.” An industrial application where the machine is being used 24/7 can be quite hard on telehandler, Boeckman says.
What weight can a telehandler lift?
Complete with hydraulic safety stabilisers and a lift capacity up to 3500 kgs, the 12 metre range is compact in construction and offers outstanding manoeuvrability complete with hydraulic self levelling stabilisers as standard, making them ideal for today’s congested sites.
