Electric Motor Grab Grab Bucket:
1.Electric Motor Grab Grab Bucket Working Principle
Electric motor grab are often used to utility of all kinds of crane with their own open and close institutions, can be load and unload material in any height. Productivity is higher than the single grab, easy to operate, loading and unloading power high. Apply to grab all kinds of loose materials. Using this grab, according to hoist height add the cable reel machine conveying energy.
Note: this grab cannot operate underwater.
Electric Motor grab with closed organization itself, the type is various, our company is equipped the standard motor hoist or winding engine on the grab bucket as open and close institutions. The motor grab can be regarded as a closed drum moved to grab itself. Since the motor grab is no longer like the four rope grab bucket which need, the up pull of the closing rope. The self-weight of the grab bucket as mining effect, so the capture force is bigger. It is suitable for capture the materials like ore etc.
