windlass for forestry crane with hydraulic grapple: It improves the vehicle’s traction, handling stability and ability to pass through difficult road conditions. Its core advantage is to reduce the risk of wheel slippage and enhance driving safety in rough terrain such as ice, snow, mud and sand
Raw material of hydraulic cylinder: the cylinder material is 16Mn steel, and the piston rod is electroplated. The material of oil pipe is aslo electroplated, which has good performance for acide and alkali resistance and anti-corrosion. Suitable for working at sea side
The type of bolts and screw are more strong and high wear-resistance with long lifetime to
make sure the working time is high-efficiency. They are HEAVYY TRUCK STANDARD
Technolog of painting: powder coating for surface dealing(big and small arms, column base, gripper teeth are red/orange, the rest are black or according to your request), has excelletn of anti-rust characteristics. It better for seaside foresty working site.
The thickness of the sprayed coating is generally 0.1-0.2 mm, which has better wear resistance, corrosion resistance, impact resistance and insulation, second, the coating of spraying has strong adhesion and is not easy to fall off, third, the coating of spraying is bright in color and long-lasting, and fourth, the coating of spraying is environmentally friendly and pollution-free
Heavy-Duty structure: designed to withstand the harsh conditions of logging environments, the crane is constructed from durable materials manganese steel plate that ensure its longevity and reliability. It’s heavy-duty design can handle substantial weights, making it available for lifting large weight timber wood logs easily
Hydraulic gabble log crane has large lifting capacity due to its high stengthen plated with bending and welding technology with excellent quality, same as construction cranes quality. Check the brief drawing please. and it can load 1900kgs at 3m, 860kgs at full length
