Structural analysis of Jib crane and its main purpose
The working strength of the cantilever of the electric single-beam crane is light. The crane is composed of a column, a slewing arm slewing drive device and an electric hoist. The lower end of the column is fixed on the concrete foundation by anchor bolts. The hoist runs in a straight line on the cantilever I-beam and lifts heavy objects.
The cantilever of the crane is a hollow steel structure, with light weight, large span, large lifting weight, economical and durable. The built-in walking mechanism adopts special engineering plastic walking wheels with rolling bearings, with low friction and brisk walking. The small structure size is especially beneficial to improve the hook stroke.
The cantilever crane is composed of a column, a swing arm, a cantilever drive device and an electric hoist.
The lower base of the column is fixed on the concrete foundation by anchor bolts, the motor drives the reducer drive device to make the cantilever rotate, and the electric hoist performs reciprocating operation on the cantilever I-beam. Cantilever cranes can help you shorten production preparation and non-productive work time, and reduce unnecessary waiting. Hyundai's cantilever crane has many specifications and varieties. No matter what your requirements for lifting weight, suspension angle, arm length and function, all specifications have a common advantage: light weight, long cantilever, and heavy lifting capacity. , Simple installation, operation and maintenance. They are completely independent and are an ideal job crane, and are suitable for outdoor cargo yards and loading and unloading platforms. The fixed column occupies a small area.
The maximum lifting height can be obtained even when the lifting headroom is very small.
The electric cantilever crane is a new generation of light lifting equipment made to adapt to modern production. It is matched with the highly reliable JPK electric chain hoist, which is especially suitable for short distances, frequent use, and intensive lifting operations. It has high efficiency, energy saving, It has the characteristics of saving trouble, small area, easy operation and maintenance. Mobile cantilever cranes are more flexible, mobile, and widely adaptable. They are necessary separate emergency hoisting equipment for high-efficiency automatic production lines. With it, the production line can be unimpeded. The crank arm series cantilever crane has the characteristics of novel structure, free extension and bending, convenient operation, high efficiency and energy saving. During operation, press the button to lift 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. Push and pull gently by hand to reach any position in the work area.
