Logging crane with diesel pump station
7.8m Wood Log Timber Crane with Remote Windlass Hydraulic Rotating Grapple Grab Diesel Pump Station with Heavy Duty Structure,We offer forwarders in many size classes, from 4.2m to 7.8m arm according to your request
- A more comfortable and safe workplace in the forest: The quiet and spacious cab has good visibility in all directions and the cleverly 2. designed gate allows you to see well. 3. The ergonomic driver’s seat offers excellent back support and can be adjusted for optimal comfort.
The thickened base column is used to support the cab and ensure personal safety during work
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.
Extended service life
3. Wear 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 (such as high humidity in the rainforest, dust in the logging yard) can be extended.
4. Fatigue life improvement: The bold design increases the fatigue strength of key welded joints (such as the connection between the column and the chassis) by more than 30%, and extends the equipment overhaul interval to more than 10,000 hours
Remote control windlass/winch： length is 30m or 50m according to your request(50m is more popular), the loading capacity is 1000kgs(dragging object weight)
The winch is mainly used to lift or pull heavy objects, it is usually composed 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 heavy objects.
The core structure consists of the winch drum, power system (e.g. motor or hydraulics), drum and 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 improve suitability for harsh environments (optional)
electrohydraulic valve: Its working principle is to receive an electrical signal through an electromagnet and generate a magnetic field to control the movement of the valve core, thereby changing the on-off state of the hydraulic system, therefore it can work when there’s out of power.
Electrohydraulic valve is Suitable for applications that require high-precision control and fine adjustment, electro-hydraulic valves can solve the problem of overshoot, eliminate water hammer, and have a constant flow function.
Its advantages are high-precision control, wide adaptation range, excellent linear control, small pressure loss and long life
Individual diesel pump station
Core Components: Diesel engine and pump body
Diesel engine: provides stable power output, high torque and high reliability, suitable for environments without power grid or unstable power.
Pump body: Conveys liquid or hydraulic oil to the target location by means of mechanical energy.
The hydraulic system drives the hydraulic pump through diesel power, which provides independent power support for the wood grabber
