Tractor cranes loader
Forest crane Machine Wood Trailer Loader Tractor usually consists of a rotating arm and a clamp. This structure allows the wood grabber to flexibly grab and carry various strip materials. In addition, the wood 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 grab machine is to load, unload and carry the wood, wood, reeds, straw and various strip materials: the front end of the wood grab machine is a wood grab machine, which is mainly used for the loading, unloading and handling of strip materials such as wood and wood.

PTO system for tractor mounted log cranes with hydraulic grapple
The role of PTO system (power take-off) in trailers is to extract power from the tractor engine, provide it with additional driving capacity, drive hydraulic pumps, compressors and other equipment, so as to improve the versatility and operational efficiency of the trailer, PTO system is widely used in a variety of commercial vehicles, such as trucks, trailers and agricultural machinery, etc., especially suitable for scenarios that require additional power
Features of the PTO system:
1. Versatility: The PTO system can extract power from the vehicle’s main engine to drive hydraulic pumps, compressors, and other equipment to enhance the vehicle’s versatility
2. Installation position: PTO axle can be installed in the rear (rear-mounted), front (front-mounted) or side (side-mounted) of the tractor, and the appropriate installation position can be selected according to different needs
