Enjue OEM and ODM Customized 20t/30t/40t/60t/100ton Heavy Duty Single/Double Electric Swivel/Slewing Lifting Pulley Hook Block Used for Port Gantry Crane CCS CE

Product Description

Product Description
Description:
Hook block is a crane and other lifting equipment in the extremely critical combination of components, hooks often with the help of pulley groups and other components suspended in the hoisting mechanism of the wire rope. It is mainly composed of hook, dynamic pulley, hook beam, pulley shaft and related bearings, nuts, anti-dehooking devices.
Hook in the process of operation is often subject to impact, must use good toughness of high-quality carbon steel manufacturing.

Classification of hook blocks:
1. Hooks are divided into single and double hooks according to the shape; according to the manufacturing method is divided into forged hooks and laminated hooks.
2. Single hook is simple to manufacture, easy to use, but the force is not good, mostly used in lifting capacity of 80 tons of the following work occasions; double hook is mostly used in lifting a larger amount of hook.
3. Stacked hook by several pieces of cut and shaped steel plate riveted together, individual plate cracks will not destroy the entire hook, security is better, but the self-weight is larger, mostly used in large lifting capacity of the crane.

Electric rotary hook block:
Description:
Electric swivel electric hook block is a kind of advanced lifting parts which integrates electric drive, swivel function and hook bearing.
The external hook block is made of high strength metal material as the core of the hook, and then equipped with a specially designed anti-dislodgement device to effectively prevent the heavy load from falling off during lifting.
The hook bolck is equipped with an electric rotating device inside, which consists of motor, reducer and rotating shaft, etc. It can precisely drive the hook to rotate flexibly to adjust the direction of the heavy load, which greatly improves the efficiency and accuracy of lifting operation.

Electric rotary hook block:
Features:
1. Motorized rotation function:
a. Precise control of the direction and angle of rotation: the angle can even be accurate to a few degrees or even smaller, which is very critical for the lifting of objects placed in demanding work scenarios. For example, in the installation of precision equipment or the stacking of goods in a small space.
b. Stable and continuous rotation: compared with the traditional way, there will not be uneven strength or interference caused by the rotation of the stagnation or sudden stop, etc., can be continuously rotated or in accordance with the set angle range of reciprocating rotation.
2. Compact and reasonable structural design, using high strength, wear-resistant and corrosion-resistant materials to extend the service life.
3. Anti-decoupling design
4. overload protection
5. Leakage protection
6. Limit switch
Advantages:
1. Improved operational efficiency:
a.Quick positioning
No need to adjust the direction of the hook by moving the crane or with the help of other auxiliary equipment.
b. Applicable to a variety of operational needs
whether it is horizontal direction and angle change, or vertical direction and angle change.
2. Improve operational safety:
a. Reduce the risk of manual intervention
b. Reliable safety protection function
3. Enhancement of operation convenience
a.Remote control
It can be integrated with the overall control system of the crane, which facilitates better coordination of the operation between various equipment.
b.Simple operation
The hook rotation can be controlled by operating buttons or operating levers, which reduces the cost of manual training and the difficulty of operation, and improves the versatility and ease of use of the device.

Routine maintenance and upkeep:
1. Hook section: visual inspection, lubrication maintenance
2. Motor section: motor inspection, gearbox maintenance, rotating shaft and bearing inspection
3. Pulley Block: Pulley inspection, lubrication and cleaning
4. Electrical control system: wiring inspection, function test
Detailed drawing of 20 tons crane hook
Applicable:
1. Industrial manufacturing field: machinery manufacturing workshop, automobile manufacturing factory, etc.
2. Logistics and warehousing industry: large warehouses, port terminals, etc.
3. Construction engineering field: high-rise building construction, bridge construction, etc.
4. Energy industry: construction and maintenance of power facilities, petrochemical enterprises, etc.
Some customized models are available.
