What types of cranes use a lattice boom?

Lattice boom crawler cranes, also known as crawler cranes, are the largest type of mobile cranes available in the construction industry. They’re so large that they often need to be disassembled, transported in pieces, and then reassembled on site.

What is a lattice crane?

Crawler cranes, also known as lattice cranes, boom lattice cranes, lattice crawlers, telescopic crawlers, etc. – are the largest of the mobile cranes. These are heavy-duty cranes that utilize “tank-like” treads to move throughout a construction site and can lift in excess of 2,500 tons.

What are lattice boom crawler cranes?

Lattice boom crawler cranes are capable of lifting great weights. The lattice structure of the boom provides strength for construction lifting yet is light enough for transport. Booms are also modular for ease of transport. Inserts can be used to extend the length of the boom.

How many types of crane boom are there?

There are two different types of crane booms: lattice booms and hydraulic booms.

What is the difference between lattice boom and telescopic boom?

In contrast to lattice booms, telescopic booms are typically hydraulic. They are hinged at the bottom where the arm meets with the body of the crane. The boom is then lifted when the crane operator pulls a switch telling the arm to raise or lower. The hydraulic system, or cables, does all the work.

Are lattice booms used on rough terrain?

Yet these are famously stable machines. Their full mass is balanced over a tracked platform, which allows them to handle jobs on a great variety of ground surfaces — even on soft terrain. They’re also adaptable.

What is a jib boom on a crane?

Booms or Jibs, This is the horizontal part of the crane, This part supports the movable electric chain hoist, and can be fixed to either a wall or the floor. Trolleys, this part slides up and down the boom and holds the electric hoist, wire rope, and lifting hook in place.

What is a luffing boom?

The Luffing Boom Crane was designed to meet the requirements of the restricted job site. With a short tail-swing and the ability to raise and lower its boom, it easily adapts to construction site demands providing complete coverage while avoiding obstructions.

What are the four types of crane?

There are four principal types of mobile cranes: truck mounted, rough-terrain, crawler, and floating.

What is Reeving on a crane?

Reeving (rope): The reeving of the hoist is the path of the rope between the hoist and the load block. Double reeving is two parts of wire rope leading off of the drum, one from each end of the drum, creating a hook movement referred to as True Vertical Lift.

What is anti two block in a crane?

Anti two-block or ATB systems help prevent the ball block from contacting the boom tip. This is called two-blocking and can cause injury or death as well as damage to the crane, load line and ball or block. The Altec ATB system consists of a load line weight suspended from a chain, connected to a boom tip ATB switch.

What is the difference between jib and crane?

The answer is not really — the terms can be used interchangeably. A crane is an arm that lifts something, and a jib is the name for a crane used in the film industry. However, we should note that large pieces of lifting equipment are often called cranes, and smaller ones are sometimes called jibs.
