Forest Timber Crane Log Trailer
The main function of wood grabber forest timber crane log trailer/Timber Trailer Crane Dump Trailer with Log Grapple ATV Hydraulic 7.8m Forestry Crane with Hydraulic Loader
1. Multi-material grasping and handling
The core function is to grab wood (logs, timber, straw, etc.), and can also process cotton, sugarcane, straw bales, scrap metal, pipes and other materials to meet the needs of diversified operations
2. The gripper design is flexible, which can accurately control the clamping force, reduce the damage to the surface of the material, and is suitable for the loading and unloading of high-value wood1
Efficient loading and unloading and stacking
Cooperate with tractors and other main engines to quickly complete material loading and unloading, stacking and destacking, and can process hundreds of kilograms to several tons of materials in a single operation, significantly improving efficiency
3. Rotation and high-precision operation
Some models are equipped with a 380° rotation function, which supports flexible adjustment of the gripping direction in narrow spaces; The high unloading height (e.g. 6.5 m) can be adapted to the loading and unloading of high-hurdle trucks

1. Hydraulic pump (from tractor or the individual diesel/electric pump station)
Provides high-pressure hydraulic oil. The flow rate determines the speed of the action, and the pressure determines the size of the output force.
2. Control valve group
The multi-way valve controls the flow direction of the hydraulic oil, enabling independent or combined operations such as opening and closing the gripper, rotation, and lifting.
3. Hydraulic cylinder/motor
The cylinder is responsible for linear motion (such as opening and closing the gripper), and the motor is responsible for rotational motion.
4. Relief valve and safety valve
Limit the system pressure to prevent overload and damage to the equipment; cut off the oil circuit in emergency situations to ensure safety.
Advantages of thickening and heavy base and vertical column
1. Enhance structural strength
Bending and torsional resistance: The thickened and thickened column can withstand greater bending moment and torque by increasing the moment of inertia of the section (such as the section of the box structure) to avoid plastic deformation or fracture during high-load operations (such as grabbing heavy logs).
Stress dispersion: The thick-walled design evenly distributes concentrated stresses to the overall structure, reducing the risk of fatigue cracks caused by excessive local stress.
2. Improve stability and accuracy
Vibration suppression: The stout column can effectively absorb the vibration generated by the movement of the robotic arm (especially the impact force at the moment of grabbing), reduce the shaking of the operation, and ensure the accuracy of grasping positioning (error ≤5mm).
Anti-lateral deflection: When working in complex terrain (such as slopes and muddy ground), the thickened column can resist the fuselage deflection caused by lateral force and reduce the risk of overturning.
3. Extend the service life
Abrasion and corrosion resistance: By increasing the wall thickness (usually from 10mm to 15-20mm), the anti-wear and anti-rust period of the column under harsh environments (e.g., high humidity in the rainforest, lumber dust) can be extended.
Fatigue Life Improvement: The bold design increases the fatigue strength of critical welded joints, such as the column and chassis joints, by more than 30%, extending the equipment overhaul interval to more than 10,000 hours
Additional option
The winch lifts or pulls the logs, which is usually composed of a horizontal cylinder, which is rotated by a motor to make the rope connected to the Timber wound on the cylinder, so as to achieve the function of lifting or pulling the wood.
The core structure includes the winch drum, the power system (e.g. motor or hydraulics), the drum and the control system.
Purpose: Equipped with movable pulley block can double the traction force of the wood grabber, realize a single winch to drag the wood, saving time and effort
Technical parameters of trailer/tow-behind
Transportation function: In rural or mountainous areas with poor road conditions, it can replace trucks to complete short-distance and efficient transportation, and adapt to complex terrain such as mud and ramps. Open design with a load capacity of 10 tons.
Towing function: The trailer is attached by a towing hook

PTO system (power take-off)
Its role in the trailer 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, especially suitable for scenarios that require additional power
Installation position: PTO axle can be installed at the rear (rear), front (front) or side (side) of the tractor, and the appropriate installation position can be selected according to different needs
Air Brake System:
The inclusion of an air brake system enhances safety during operation and transport. Sistema de frenos de aire: La inclusión de un sistema de frenos de aire mejora la seguridad durante el funcionamiento y el transporte. Esta característica garantiza una potencia de frenado efectiva, lo que brinda tranquilidad a los operadores al maniobrar en pendientes o durante el viaje en carreteras públicas
