Log crane forestry loader for tractor
Forestry drygrass crane with hydraulic gapple mounted behind tractor, H type support legs
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
4.7m log crane with 50hp tractor
八 type support legs for Grua forestal para troncos con garfio hidraulico
The hydraulic outriggers enhance the stability of the operation and prevent overturning, and the horizontal adjustment is realized by the hydraulic drive, forming a stable triangular base when supporting, and improving the anti-overturning ability.
Technical Advantages
1. High stability: By adjusting the height and span of the outriggers, it can adapt to different ground conditions to ensure the level of the equipment
2. Convenient operation: electric or remote control replaces the traditional hand crank to achieve fast lifting and precise leveling
3. Large bearing capacity: The hydraulic system can provide greater support force, which is suitable for heavy equipment, such as tractors, trucks
