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.
What is a hydraulic truck crane?
Hydraulic truck cranes are used to lift heavy loads to tall heights, and it’s important that the truck be completely stable during the lifting operation. The tires don’t offer the stability needed, so the truck employs outriggers that act as balances to keep the crane from leaning too much to one side or the other.
What is boom truck crane?
A boom truck crane, or a telescoping crane, uses high-boom angles and a hoist to lift loads. These cranes are designed for strength and stability and are typically used to lift heavy loads vertically.
What’s the difference between a crane and a boom truck?
These cranes are designed for a construction project’s early stages. They travel on rough terrain with large wheels. Whereas boom trucks can move independently, you must use a heavy haul trailer to transport rough terrain cranes.
What is a hydraulic boom?
Boom – The large arm mainly responsible for lifting. Counterweights – Multi-ton weights placed on the back of the cab to prevent the crane from tipping during lifts. Two-gear pump – Hydraulic pump system that uses two rotating gears to pressurize oil. Jib – Lattice structure that extends out of the boom.
What are the advantages of hydraulic crane?
Compact, easy to use. An incredible amount of power is generated through hydraulics, allowing hydraulic truck cranes to operate more nimbly than conventional cranes. Eliminating the need for cumbersome pulleys and gears, hydraulic cranes are also easier to maintain because of fewer moving parts.
What is the principle of hydraulic crane?
The hydraulic crane project employs the principle that any force applied to an incompressible liquid will propagate through the liquid, without significant loss of strength, to effect whatever is on the other side. When pressure is applied, the oil is forced to transfer to the other part of the crane.
Is a boom truck considered a crane?
For Custom Truck One Source, a boom truck generally refers to a hydraulic crane mounted onto a commercial truck chassis. Most of these boom trucks are straight, telescopic booms, but the company also has articulated cranes that fit in the category of boom trucks.
How much can a boom truck lift?
Boom Truck Information
The Terex Stinger BT3470 Boom Truck Crane has a maximum lift capacity of 17 tons and a three section, full-power maximum boom length of 70 feet. A two stage telescoping jib extension of up to 40 feet is optional.
What do crane trucks do?
The crane truck is a portable boom crane mounted on an industrial truck; it may be used with hooks, grabs, and slings for bundled or coiled material.
Can a forklift be used as a crane?
Forklifts are not considered to be cranes and are specifically excluded from these requirements EXCEPT when configured to hoist and lower (by means of a winch or hook) and horizontally move a suspended load. … Many forklift manufacturers will not grant such approval.
Are boom lifts safe?
Boom lifts are an important component of the proper deployment and completion of many construction projects. However, given the size, scale, and structure of this type of equipment, they can also pose substantial risk and have the potential to cause serious injury if effective safety measures are not followed.
How much does a boom truck cost?
A new 23.5 ton boom truck with standard equipment, a 92′ boom, 44′ jib and a maximum tip height of 144′ sports an average price of $129,850.
How does a hydraulic boom work?
The pressurized hydraulic fluid pushes the piston in and out of the cylinder, allowing the piston to lift or move a load. … When one piston is compressed, the displaced oil forces the other piston to extend. For most cranes, the pressure needed to move the pistons is generated by a pump.
What is a hydraulic system used for?
Hydraulic systems are mainly used where a high power density is needed or load requirements chance rapidly. This is especially the case in all kinds of mobile equipment such as excavators and in industrial systems such as presses. In wind turbines, hydraulics is used for pitch and brake control.
What is hydraulic truck?
Essentially, a hydraulic boom truck is a mobile type of crane, which is moved around on roadways with a conventional diesel engine, but which has its boom and crane completely operated by hydraulic systems.
