4.2m log trailer crane
4.2m log trailer crane is more popular for home use. Through hydraulic or mechanical drive, the gripper closure is used to achieve fast grasping and stable clamping of wood, which is suitable for different forms such as logs, branches, and wood.
Equipped with 360° rotation function, the gripping direction can be flexibly adjusted to adapt to the complex working environment.
Cooperate with tractors, excavators or loaders to efficiently transfer timber over short distances, load and unload vehicles and organize yards
Accurately control the opening and closing degree of the gripper, classify or arrange the wood according to size, realize the automatic stacking or dismantling of wood, and optimize the utilization rate of storage space. tractor trailer with crane
log trailer and crane uses tractor hydraulic pump
log trailer and crane with Pump station driving. As a key component of the hydraulic system, the pumping station controls the direction, pressure and flow of hydraulic oil through the hydraulic valve, so as to provide the hydraulic power and control functions required for the mechanical hydraulic execution of the wood grabber and log trailer crane, and ensure the normal operation and performance of its hydraulic system
Windlass for log trailer crane: It lifts or pulls heavy objects, it usually consists of a horizontal cylinder, which is rotated by a motor to make the rope connected to the heavy object wound on the cylinder, so as to achieve the function of lifting or pulling the heavy object.
The core structure includes the winch drum, the power system (e.g. motor or hydraulics), the drum and the control system.
Purpose: Equipped with a movable pulley block to multiply the traction force and realize a single winch to drag heavy loads
Through power drive and mechanical structure innovation, the winch has become an indispensable tool for off-road and harsh environment operations. In addition, details such as LED remote control lighting at night enhance the suitability of harsh environments

Red log trailer crane is update model which have 8 the blocking tubes to protect the log or wood safe and ensure the trailer balance when works
4WD System It can improve the traction and passability of the vehicle and is suitable for various road conditions.
The four-wheel drive performs better on snow slopes, and the power covers all four wheels to avoid power interruption caused by the slippage of a single drive wheel;
It can also maintain continuous power output on rough and muddy roads, avoid power loss caused by single-wheel skidding, and have strong adaptability to complex road conditions
