What are the main components of a crane?
Cranes consist of four key components:
- Hook. The hook element of a crane is the part that holds or carries the load and connects it to the hoisting element.
- Hoist. The hoist element of a crane provides the vertical lifting and lowering power.
- Trolley.
- Bridge.
What are the arms on a crane called?
A jib or jib arm is the horizontal or near-horizontal beam used in many types of crane to support the load clear of the main support. An archaic spelling is gib. Usually jib arms are attached to a vertical mast or tower or sometimes to an inclined boom.
What are the components of a crane runway system?
The runway system of an overhead crane can include the beams, columns, and rails that the crane runs along. The bridge or girder end trucks run along a rail which is secured to the top of the runway beams.
What are the different parts of a deck crane?
Three separate drives provide the principal movements: a hoisting motor for lifting the load, a luffing motor for raising or lowering the jib, and a slewing motor for rotating the crane.
What kind of structure is a crane?
Tower cranes and communication towers are examples of frame structures. Frames are made from bars joined together to form a ‘framework’. This is one of the most economical ways of building structures. Some modern buildings have a frame structure which can only be seen during construction.
What part is the jib on a crane?
Jibs are secondary arms that extend off of the end of a boom. They allow the crane to have extra reach, but they often reduce the amount of weight that a crane can hoist. Jibs often use a lattice design in order to reduce the amount of weight that they add to a load.
What is boom on crane?
A crane boom is a long fixed or hydraulic arm that is used to move large objects in construction. It bears most of the weight when positioning a load, and its length determines a crane’s maximum reach. Crane booms take on a variety of roles and appearances depending on the type of crane.
What is mast in tower crane?
Tower crane mast It is a metal lattice structure with a normally square section, whose main mission is to provide the tower crane with sufficient height. Normally it is formed by lattice modules that facilitate the transport of the crane.
What are the names of the parts of a crane?
The Parts of a Crane – all you need to know Hook. The load is supported using a hook which connects to the hoist and to the end effector. Hoist. The hoist is what creates the lift in lifting systems by holding, raising, or lowering, the load using wire rope or chains. Trolley. Bridge. Columns. Runway. End Trucks. Electrification. Controls. Bumpers.
What are the important parts of a crane truck?
Boom. The crane boom is the easiest feature to recognize and the most essential part of a crane truck.
What are components of overhead crane?
The overhead crane includes four major parts: the body structure, the trolley (lifting and traveling mechanism), the crane traveling mechanism and the electrical equipment. The lifting mechanism, trolley traveling and crane traveling mechanisms are the three working mechanisms of the crane.
What is parts build a crane?
Larger, heavier duty, purpose-built “truck-mounted” cranes are constructed in two parts: the carrier , often called the lower, and the lifting component , which includes the boom, called the upper. These are mated together through a turntable, allowing the upper to swing from side to side.
