Jib Crane In Wall Type

Wall type jib crane only need to install on the wall or column, and without any ground area. Column jib crane has the advantages of small occupation area. It can fix with method of embedded anchor bolts or heavy anka bolt. This jib crane could shorten handling time and improve the working efficiency. Workers can lift and handle all kinds of equipment at any time. That could reduce non productive work time and labor intensity of workers greatly.

If you only want to convey equipment or workpiece at small range, you may consider to use jib crane. In some workshops, every worker has a jib crane. So there is no need for large investment vehicle. While the working efficiency also has been improved.

Converter used in the system of this jib crane has automatic operation mode with energy-saving. It could improve power factor and operating efficiency of the whole machine greatly. Wall type jib crane has monitoring system with a panel which is all in Chinese. So it is very convenient to technical personnel. System in wall type jib crane has hook safety monitoring. You can ensure product safety in the decentralization process. And you can easy do goods para.

Fault In Overhead Crane System

Phase failure in overhead crane system is caused by main control circuit of electric appliance damaged. In order to solve this problem, we will protect the equipment with maintenance mainly to prevent burning motor. So the equipment motor must be disconnected effective from power line. Only you ought to offer is sending electricity to main control circuit. Then you can start or stop. If you have been checked and analysis controlled electric appliance, it will not cause the problem of phase failure.

Sometimes the overhead crane race to the top, we should take proper measures to solve this problem. At first, it may be caused by limiter of the system. The limiter has been controlled the hook up and down. Besides the operator who negligence make the problem. When people installing the overhead crane system, they forget to do corresponding modulation to controller order. That will lead to hidden danger for limiter contacts and even occur the phenomenon of top punching.

Certainly the overhead crane system could not be checked and repaired for long term. Without these maintenance, the limiter also exist many hidden danger, even the parts on the system will be loosen.

Lifting And Operation Mechanism Of Electric Hoist

Electric hoist is composed by three parts. They are lifting mechanism, running mechanism and electrical device. Lifting mechanism makes the wire rope drives the hook device rising or falling. That rotate with hollow axle driving drum through speed reducer.

Speed reducer are all adopt helical gear with three stage reducer. Gear and shaft are processing of alloy structural steel or oil steel. Then the speed reducer processed by hot treatment to ensure it could be reliable and service life. The box body and cover are made of cast iron. It usually has good shock absorption performance and reliable sealing.

Drum using seamless steel manufacturing. It uses spline transmission power. Drum shell is welded by steel plate. The The reel device is the core part of gourd. The plates is connect with operation mechanism. Both sides are connected with the lifting gear motor respectively. The wire rope and hook device is in combining working. Installing a limited guide rod device above the front shell. The hook is forging by steel which is in high quality. The running mechanism consists of electric car,running  motor, reducer, driven car and other components. Running mechanism make the motor do reciprocating movement through the side plate and the reel device.
