When the crane uses a suspended cable trolley (or cable guide), the cable should be prevented from being worn and excessively bent during movement. For cables with an outer diameter not greater than 8mm, the curvature diameter of the cable suspension bending plate should be at least the outer diameter of the cable. 6.3 times; for cables with an outer diameter greater than 8mm, at least 8 times the outer diameter; for cables with an outer diameter greater than 12.5mm, at least

The reason for the falling of the lifting hook? 1. The unsafe state of the crane is firstly the risk brought by the non-standard design, such as overload protection failure, insufficient strength of the balance wheel and axle, no decoupling prevention device, unreasonable selection of slings, etc.; followed by manufacturing defects and installation defects, such as material selection Improper processing and poor processing quality make equipment with hidden dangers put into use.

Analysis of the reasons why the crane electric hoist cannot run? 1. You can first check whether the power fuse of the equipment is blown. If one phase is broken, it is impossible for the electric hoist to rotate. The starting torque of the electric hoist of the crane is zero, so that the motor of the equipment does not work. It will work, it is necessary to replace enough fuses. 2, there is the voltage of the grid is too low,

Maintenance requirements for hoisting machinery: 1. Construction hoisting machinery maintenance contracts, systems and plans. If the construction hoisting machinery user unit does not have the corresponding qualification certificate for professional contractors of hoisting equipment installation engineering, it should be notified in the construction hoisting machinery installation Before signing a construction crane maintenance contract and an accident emergency rescue contract with the equipment installation and maintenance unit,

What is a special hoist crane? Some hoist cranes suitable for use in special fields, special occasions and special environments are called special hulu cranes. For example, it is suitable for explosion-proof hoist cranes that can operate safely and reliably in flammable and explosive environments, and anti-corrosion hoist cranes suitable for operating in highly corrosive occasions. to be able to reliably

As the demand for lifting machinery continues to increase, the crane market is also constantly developing, and the market competition is very serious for crane manufacturers. How can we develop our own brand? Then the development of crane manufacturers is required to keep pace with the times. In today's rapid development of technological upgrading, some new things are updated very quickly. Today's mainstream products,
