Off - road forklifts are engineering vehicles that can safely and efficiently carry out material loading, unloading, stacking and handling operations on slopes and uneven ground. The following is an introduction to it:
Characteristics
- Good Passability: Equipped with large - diameter wide - base off - road tires, with a minimum ground clearance of over 300mm, a departure angle of over 30°, and a four - wheel drive function combined with a differential lock, it can easily handle complex road conditions such as potholes and muddy areas.
- High Mobility: The maximum driving speed is usually 30 - 40km/h, the power factor exceeds 0.65, it has good acceleration performance, and the climbing ability can reach 25° - 30°.
- High Stability: Larger wheelbase and track width increase lateral and longitudinal stability. The frame swing angle can reach ±30° - 40°, and the front axle can swing vertically relative to the frame by ±8° - 12°.
- Reliable Braking: Except for small - tonnage forklifts that use expanding - shoe brakes, most are disc brakes. Large - tonnage forklifts also have wet brakes, and independent hand brakes are commonly used for parking brakes.
Structure
- Chassis: It adopts a hinged frame with a simple steering system, which can achieve a small turning radius. In terms of axles, the rear axle is fixed to the frame, the front axle can swing vertically relative to the frame, and a support hydraulic cylinder is set between the frame and the front axle.
- Power Transmission: There are various methods such as mechanical transmission, hydraulic shift mechanical transmission, hydraulic transmission, and hydrostatic transmission. The full - power matching method is used, and the maximum load is the full - load climbing condition.
- Working Device: The structural form is similar to that of a counterbalance forklift. It can be equipped with forks or replaced with a variety of attachments, such as clamps, to improve work efficiency.
Application Fields
- Construction Sites: It can transport building materials such as steel, wood, and bricks on the rugged construction site ground, and can also carry out high - altitude operations to lift materials to the designated location.
- Mining Operations: In the mining area, it is responsible for loading, unloading, and transporting ores, waste residues and other materials, adapting to the harsh road conditions in the mining area.
- Oilfield Development: It is used for the transportation of oilfield equipment, the loading and unloading of oil pipes, and the transportation of materials, and can play a role in oilfields with different terrains such as deserts and grasslands.
- Wharf Cargo Yards: It can load, unload, and transport containers, and can work normally even in non - flat road areas of the wharf.
