The structure and use of the cantilever crane

The working strength of the cantilever crane is light. The crane is composed of a column, a rotary arm rotary drive device and an electric hoist. The lower end of the column is fixed on the concrete foundation by anchor bolts, and the cantilever rotation is driven by a cycloidal pinwheel reduction device. The beam runs in a straight line from left to right and lifts heavy objects.

 

The cantilever of the crane is a hollow steel structure, which is light in weight, large in span, large in lifting capacity, economical and durable. The built-in running mechanism adopts special engineering plastic running wheels with rolling bearings, which has low friction and light travel; small structure size is especially beneficial to improve the hook stroke.

 

The cantilever crane consists of a column, a slewing arm, a cantilever drive device and an electric hoist. The base of the lower end of the column is fixed on the concrete foundation by the anchor bolts, the motor drives the reducer drive device to make the cantilever rotate, and the electric hoist runs back and forth on the cantilever I-beam.

 

Jib cranes can help you shorten production preparation and non-productive work time, and reduce unnecessary waiting. There are many specifications and varieties of cantilever cranes. No matter what requirements you have on lifting weight, cantilever angle, boom length and function, all specifications have a common advantage: light weight, long cantilever, large lifting capacity, installation , Operation and maintenance are simple. They are completely self-contained, making them an ideal work station crane and suitable for use in outdoor yards and loading docks. The fixed column occupies a small area.

The maximum lifting height can be obtained even with very small lifting clearance. The electric cantilever crane is a new generation of light lifting equipment made to adapt to modern production. With the high reliability of JPK type electric chain hoist, it is especially suitable for short distance, frequent use and intensive lifting operations. It has high efficiency, energy saving, It has the characteristics of saving trouble, small footprint, easy operation and maintenance.

 

The mobile cantilever crane is more flexible and adaptable, and it is a separate emergency hoisting equipment necessary for efficient automatic production lines. With it, it can ensure that the production line is unobstructed. The jib series cantilever cranes have the characteristics of novel structure, flexible extension, flexible operation, high efficiency and energy saving. During operation, press the button to hoist the load, and use the bending and suspension movement of the beam to avoid objects in the control work area to maximize the work area. Gently push and pull by hand to reach any position in the work area.

 

The working strength of the cantilever crane is a light crane, and the cantilever of the crane is a hollow steel structure, which is light in weight, large in span, large in lifting weight, economical and durable. Safe and accurate positioning. The built-in running mechanism adopts the guide rail pulley device with low friction, and the walking is brisk.

 

Suspension control 270-degree angle, can be matched with chain hoist, linear balancer, VPL spreader, optional galvanized or painted surface. According to the difference of the running track, the column-type cantilever crane can be divided into two types: the inner-mounted orbital cantilever crane and the external-mounted orbital cantilever crane. When used together with the PK-type electric chain hoist, it can be quickly and agilely hoisted on the job. materials. The column-type cantilever crane can be installed in any position and is suitable for use in various occasions. It is the ideal choice for workshops where other conveying tools cannot be fixed structurally.
