Application Showcase
1. Forestry operations: The common use of wood grabber in forestry is to move wood, which can quickly and accurately grab wood and carry it to the designated location, which greatly improves the efficiency of wood processing. In addition, the wood grabber can also be used for tree pruning and felling
2. Agricultural field: In the agricultural field, the wood grabber can be used to process crops, such as straw, pasture, etc., grabbing them from the field and stacking them for subsequent processing and utilization. In addition, the log grabber can also be used for farmland transformation work, such as digging ditches, leveling land, etc
3. Industrial & Manufacturing: In the field of industrial and manufacturing industry, wood grabber is widely used in the handling of various materials, including heavy materials such as wood, sand, coal, steel, etc. It can also be used as an auxiliary device on the production line for picking and placing products, increasing production efficiency 23.
Structural features
A log grabber usually consists of a boom with a swivel function and a clamp. This structure allows the grab machine to flexibly pick up and handle a wide range of strips. In addition, the log grabber can be installed on different chassis according to actual needs, such as tractors, forklifts, dump trucks, etc., to adapt to different working environments and needs
The main function of the wood grabber is to carry out the loading and unloading and handling of wood, timber, reeds, straw and various strip materials: the front end of the wood grabber is the wood grabber, which is mainly used for the loading, unloading and handling of timber, wood and other strip materials

Support legs/outriggerrs with hydraulic system

The hydraulic outriggers enhance the stability of the operation and prevent overturning, and the horizontal adjustment is realized by the hydraulic drive, and a stable rectangular base is formed when supported, which improves the anti-overturning ability.

The H-leg is designed with horizontal and vertical double hydraulic cylinders, with large spans and individually adjustable height, which is suitable for large and medium-sized cranes and complex terrain, it’s mainly used at truck and tractor.

The main function of the A-shaped outrigger/support legs is to increase the support base of the log grabber, reduce the burden on the tire, and improve the anti-overturning stability of the whole set of log grabber and trailer, so as to improve the lifting capacity
The A-line outriggers are provided by a support device installed at the base of the log grabber, containing a fixed part and a movable extension part, which are usually installed by the crane; The two legs, the left and right sides are separated, which can be operated at the same time and can be expanded and contracted separately
peculiarity
1. Increase the support base: The A-shaped outrigger can disperse the weight of the wood grabber, reduce the pressure on the ground, and improve the overall stability by increasing the support base of the wood grabber.
2. Reduce the burden on the tire: Through the support of the outriggers, the burden on the tire can be significantly reduced and the service life of the tire can be prolonged.
3. Improve anti-overturning stability: The design of the outriggers allows the wood grabber to remain stable even on uneven ground, reducing the risk of overturning.
4. Adapt to different terrains: The height of each leg can be adjusted individually to adapt to various uneven terrain and sloping ground.
5. Simple structure: The A-line outrigger is usually telescopic by a cylinder, with simple structure and light weight, which is suitable for small cranes.

八 type support legs/outriggers has the same funtions of A type, however The width of the support is different, 八 type is more wider
