Universal overhead crane
High working performance: with high working efficiency and stable performance, it can meet the needs of various industrial production. Parameters such as lifting and running speed can be adjusted according to actual needs, and the operation is flexible and convenient.
Good safety: equipped with a variety of safety protection devices, such as lifting height limit device, travel limit device, overload protection device, etc., can effectively ensure the safety of operators and equipment.
Strong versatility: suitable for all kinds of indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway traffic, port terminals and logistics turnover departments and places, can be used to lift all kinds of ordinary heavy objects, can also be equipped with a variety of special lifting gear for special operations.
Easy maintenance: high degree of standardization, serialization and generalization of parts, easy maintenance and replacement, reducing maintenance costs and downtime

Structural features:
Bridge: The box-shaped main beam structure is adopted, which has high strength and stiffness and can withstand large loads. The main beam is usually welded from steel plates, and the welding process requires higher requirements to ensure the quality and strength of the weld. The box structure also has good torsional resistance, which can ensure the stability of the crane during operation.
Trolley: The trolley is an important part of the crane, responsible for lateral movement on the bridge, so as to achieve the horizontal handling of heavy objects. Trolley conduction generally adopts the new device of track cable conduction of I-beam, which has good conductivity and reliability.
Lifting mechanism: Lifting mechanism is a key part of the realization of heavy lifting and falling, usually according to the requirements can be set up two sets of safety devices to increase the reliability of the lifting process. The lifting mechanism is generally composed of motor, reducer, reel, wire rope, hook and other components.
Operating mechanism: including large vehicle operating mechanism and small vehicle operating mechanism. The trolley running mechanism is used to move the crane as a whole along the longitudinal track of the workshop, and the trolley running mechanism makes the trolley move horizontally on the bridge. The wheels of the operating mechanism are usually made of cast steel or alloy steel materials, which have high wear resistance and load carrying capacity.
Control room: The control room has a wide vision, comfortable work, flexible operation, and provides a good working environment for the operator. The control room is equipped with a variety of control buttons, handles and dashboards, etc., to facilitate the operator to operate and monitor the crane.
Parameter specifications:
Lifting weight: 5t to 550t/100t, common 5t, 10t, 16/3.2t, 20/5t, 32/5t, 50/10t, etc., where the numerator indicates the main lifting weight, and the denominator indicates the sub-lifting weight (if there is a sub-hook).
Span: 5 meters to60 meters, the span depends on the actual needs of users
Hoisting mechanism of the universal overhead crane adopts the classic parallel axis, the traveling mechanism of crab adopts the low-speed shaft centralized driving structure, and the traveling mechanism of trolley adopts the structure of independent driving on both sides.
The cranes can be divided into hook type (QD), grab type (QZ) and magnet type (QC) according to the method of handling materials. According to the operation mode, it is divided into ground operation, air operation and remote control operation.
