Grab crane classification

Grab bucket by about two or more combinations of jaw opening and closing crawl and unloading bulk material spreader, composed of a plurality of jaw gripper grab is also called.

Classified by shape
Can be divided according to the shape and orange petal shell-shaped grab grab, the former consists of two full buckets, the latter having three or more of the jaw plates.
Classification by drive
Press the drive can be divided into mechanical and hydraulic grab grab two categories.
A hydraulic grab
Hand pallet jacks grab itself with the opening and closing structure, generally with hydraulic cylinders driven by a plurality of hydraulic jaw plates, also called hydraulic claw grab. Hydraulic grab the hydraulic class-specific equipment used widely, such as hydraulic excavators, hydraulic lifting tower.
Hydraulic grab products are hydraulic structures, by a hydraulic cylinder, bucket (jaw), connecting column, bucket ear plate, earmuffs bucket, bucket teeth, adapters and other parts composition, so welding is the most critical hydraulic grab production process, welding quality directly affects the structural strength and hydraulic grab life. Another hydraulic cylinder is the most critical drive components.
Hydraulic grab is a special industry equipment, accessories, need special equipment to high-efficiency, high-quality work performed, such as: CNC plasma cutting machine, beveling edge milling machine, bending machine, welding positioner machine, boring machine, hydraulic test stand, etc. .
Special hydraulic excavator grab divided into two kinds of rotating and non-rotating, do not turn back to grab excavator bucket cylinder oil used without addition of hydraulic valve block and piping; grab to be added back to the turn of the a hydraulic valve block and piping to control.
Special hydraulic excavator grab applicable occasions:
1, building foundation pit excavation pit excavation and mud, sand, coal, gravel loading.
2, is particularly suitable for trench or the side of the restricted space excavation and loading.
