Various crane lifting attachments are used with overhead and gantry cranes to handle different loads or materials. The below the hook attachments are one of the important parts of cranes, which directly affect the lifting efficiency of cranes.
The following will introduce different types of below-the-hook lifting attachments for your reference.
1. Four-rope Mechanical Grab
The four-rope mechanical grab can be used for single girder and double girder cranes:
The four-rope mechanical grab is suitable for grabbing loose materials:
2. Electric grab
The electric grab itself has a closing mechanism. Generally, a standard electric hoist or hoisting mechanism is installed on the grab as an opening and closing mechanism.
The electric grab is very suitable for grabbing ore materials due to its large grabbing capacity.
3. Hydraulic grab
The hydraulic grab has a large grabbing capacity and is an ideal lifting device for large ore, pig iron, scrap steel, garbage, iron filings, straw, slag and other materials.
Hydraulic grabs are mainly used in industries such as steel, mines, forest farms, coal mines, seaports, scrap steel recycling, garbage disposal, and biological power generation.
1. MW5 electromagnetic chuck
MW5 series electromagnetic chuck is used to lift cast iron ingots, steel balls, pig iron blocks, as well as various miscellaneous iron and re-burning materials in foundries.
2. MW61 electromagnetic chuck
MW61 electromagnetic chuck is used to efficiently load and unload scrap steel in narrow hopper-shaped containers, such as the fast loading of scrap hoppers in steel mills.
3. MW12 electromagnetic chuck
The MW12 electromagnetic chuck can lift and transport bars, flat irons, angle steels that are not bundled or simply bundled. There are normal temperature type and high temperature type.
1. Motorized coil tongs
The motorized coil tongs are widely used in the rolling and handling of coils in steel mills, stacking in warehouses, etc.
It can be equipped with a rotating mechanism to achieve 270° rotation.
The rated lifting capacity is 10t, 20t, 30t, 40t, etc.
2. C-hook
The C-hook can be designed for various coil sizes.
The rated lifting capacity is 3.2t, 5t, 10t, 16t, 25t, 32t, etc.
3. Slab tongs – designed for moving various slabs. The slab clamp adopts lever type working principle.
4. Round ingot tongs – used to move round ingots in the horizontal position
5. J-hook ladle beam – used for lifting various ladle in metallurgical industry
1. Electric telescopic container spreader
Electric telescopic container spreader can lift ISO standard 20-foot, 40-foot, and 45-foot containers. All movements of the spreader are driven by motors.
It has the advantages of simple and reliable structure, light weight, convenient maintenance and low use cost.
2. Hydraulic telescopic container spreader
All mechanisms on the spreader are driven by hydraulic system. The spreader is equipped with a hydraulic oil pump, various control and protection hydraulic valves, a telescopic hydraulic motor and a rotary lock cylinder, etc. Through the on or off of the solenoid valve to drive the action of each mechanism.
3. Rotating container spreader
The difference between electric and hydraulic container spreaders:
