Mechanical grapple are widely used in our daily lives; grabbing wood, paper, plastic, steel, and forage all need grabbing machines, especially the front-end working device, wood grabbing device is very important. Let’s talk about grabbing machines today. Some structural features, applicable paths and selection methods of front-end wood grabber;
The composition of the grapple:
The wood grab is composed of left and right sleeves, connecting rods, left grab claw, right grab claw, left grab claw control rod, right grab claw control rod, frame, hydraulic cylinder, rotating A series of institutions such as motors.
Classification of mechanical grapple
(1) Mechanical log grabber; (2) 360° rotary hydraulic log grabber; (3) non-rotating hydraulic log grabber.
One type is the mechanical timber grab that does not need to modify the excavator pipeline and hydraulic system (low-cost type);
One type is the need to modify the wood grab line and hydraulic system of the rotary excavator to meet the needs of 360-degree rotation. (Convenient, practical, cost-based);
Configuration of the mechanical grapple
Mechanical excavator wood grabber: It is driven by the excavator bucket cylinder, without additional hydraulic blocks and pipelines;
360° rotary hydraulic excavator wood grabber: need to add two sets of hydraulic valve blocks and pipelines on the excavator to control;
Non-rotating hydraulic excavator wood grabber: need to add a set of hydraulic valve blocks and pipelines on the excavator to control.
Selection of mechanical grapple:
According to the user's actual working conditions and environment, we can be divided into: standard large and small arms with wooden grabs, and extended arms with wooden grabs (extension arms are generally not recommended to be too long). If the user does not consider the problem of loading, they can choose a mechanical log grab, which is cheap and cost-effective; if the customer needs to grab and handle, it is recommended to use a rotary log grab, which has high practicability and saves working time. Simple and convenient.
