LDZ Technical Information
Grab crane is mainly consisted of bridge frame, crane traveling mechanism, lifting trolley, electric equipment, grab bucket, etc. This single girder overhead crane with grab is usually used to grab and lift common materials with work duty not more than A4.
Lifting capacity: 10t;
Span: 7.5m ~ 22.5m;
Working temperature: -20℃ ~ 40℃;
Relative humidity ≦ 85%.
Working materiel density: 0.6 ~ 2.9 t/m³
Volume of grabs: 0.75m³, 1m³, 1.5m³and 2.5m³.
Two electric hoists are equipped on this crane, one works as lifting mechanism, another one works as open-and-close mechanism. This single girder overhead crane with grab has advantages of compact structure, beautiful exterior, convenient for operating, economical and practical. And it's a perfect small equipment to grab materials.

Application of grab crane
Grab crane is widely used in power station, storage, smelting workshop of steel mill, port, cement plant, and waste recycling station, etc. to load and unload scattered objects. The grab crane has a high requirements on heat, dust, and aggressive environment.
Grab bucket
Grab bucket is a tool for efficiently loading and unloading materials such as, sands, coal, mineral powder and bulk chemical fertilizer, etc. The grab bucket is equipped for the crane to grab bulk materials.
There are two types of grab buckets, the orange grab and clamshell grab. The orang grab is suitable for handling materials, such as, steel scrap, big iron stock, garbage, and steel mills whereas the clamshell grab is used to lift small bulk materials, such as, grain, bulk fertilizer, etc.
