Cantilever crane design instructions

Cantilever cranes are boom cranes where the retrieval device is suspended at the end of an arm or hung on a lifting trolley that can run along a cantilever, where the rotation arm can rotate but cannot be pitched. Cantilever crane is a small and medium-sized lifting equipment developed for adapting to modern production in recent years. It has a unique structure, is safe and reliable, and has the characteristics of high efficiency, energy saving, time, labor and flexibility. In the short-distance, dense transport occasions, more superior than other conventional lifting equipment. The cantilever crane is light-duty, and the crane consists of an upright column, a swivel arm rotary drive and an electric hoist. The lower end of the column is fixed on the concrete foundation by the anchor bolts, and the cycloid pin wheel device drives the cantilever to rotate by deceleration. The electric hoist moves right and left on the cantilever beam, and lifts the heavy object. The cantilever crane has the advantages of light weight, large span, large lifting capacity, high efficiency and energy saving, easy operation, small footprint, easy operation and maintenance, etc.

The chassis of the crane is made of Q235B material, the column is made of seamless steel pipe, and the bearing is made of famous manufacturers of Ha, Wa and Luo. In order to ensure that the cantilever 360 degrees does not affect the winding of the cable, our company has designed a carbon brush conductive rotating device. When the crane is working, it can rotate any angle, without going to cause the winding and twisting of the conductive cable and avoid unnecessary. Accidents and work breakdowns.

Crane operation is wired handle operation and wireless remote control operation, the crane power supply is 380V 50Hz, the control power is 36V, and the crane is installed with upper and lower limits to ensure that the hanging will not be caused by sudden problems during work. .

When the crane is installed, a process board is reserved when drilling the chassis plate of the crane. When using the infrastructure, the bolts are embedded according to the process board. After the cement is dried, the crane is directly installed on the dry cement foundation. However, the site is beautiful, but it can also speed up the work schedule.
