The LD end beam (also known as a crane end beam or trolley end beam) is a key component of bridge and gantry cranes (such as LD type electric single-beam cranes), responsible for supporting and driving the crane's horizontal movement along the track. Its structural strength and smooth running directly affect the operational safety and service life of the crane.
Rubber-tired wheels in crane accessories are wheels with a layer of rubber material wrapped around a metal hub. They are mainly used in various crane equipment to support and move cranes and their suspended loads.
Metallurgical electric hoists use a motor to drive a reducer, which in turn rotates the drum. The steel wire rope on the drum winds or unwinds, thus lifting and lowering the heavy object. During the lifting and lowering process, the electrical control system precisely controls the speed and position of the heavy object by controlling the forward and reverse rotation and speed of the motor. When the electric hoist reaches its limit position, the limit protection device automatically cuts off the power to prevent the electric hoist from exceeding the safe range.
