MR30Y 3ton 4WD Rough Terrain Forklift with Bucket
The four-wheel drive off-road forklift is a kind of engineering vehicle that can safely carry out loading, unloading, stacking and transfer operations on slopes and uneven ground, the same as the balance forklift. It can be equipped with forks or replace various attachments to improve work efficiency. Cross-country forklifts have a variety of structural types, which have been developed rapidly abroad.
Four-wheel drive cross-country forklift
Structural characteristics of four-wheel drive off-road forklift
1. It has outstanding passability and off-road all-wheel drive. There is no differential between the axles, and large-diameter wide-base off-road tires are used. The minimum ground clearance of the vehicle is more than 300mm and the departure angle is more than 30°.
2. Use articulated frame. The swing angle of the frame is generally ±30°~40°. The steering system is simple and does not require expensive steering drive axles. It can complete a smaller turning radius. Operate the steering wheel to make the frame swing horizontally and make the fork easy to align. For materials, for small-tonnage cross-country forklifts, an integral frame can be selected, single-axle drive and drive axle with differential lock.
3. All-wheel braking. Except for small-tonnage forklifts that use expanding shoe brakes, most of them are caliper disc brakes, and large-tonnage forklifts also use wet brakes. The parking brake is the most widespread independent hand brake.
4. For 2t~3t articulated cross-country forklifts, the front and rear axles are common.
5. The rear axle of the four-wheel drive cross-country forklift is fixed to the frame, and the front axle can swing straight with respect to the frame by ±8°~12°. There is a supporting hydraulic cylinder between the frame and the front axle. When the forklift is lifting, the hydraulic cylinder is operated to make the lifting mast maintain a lateral plumb condition; when the forklift is moving, the upper and lower chambers of the hydraulic cylinder are allowed to pass through Collusion of damping holes helps to improve the ride comfort of the vehicle.

6. There is a larger wheelbase and wheelbase. Add the lateral and longitudinal stability of the forklift.
7. Outstanding mobility. The maximum vehicle speed is generally (30-40) km/h. The power factor is above 0.65, the travel speed is good, and it has a climbing ability of 25°~30°.
8. Larger mast angle. This is all necessary for safe operation and traveling on uneven ground, generally 10°~15° front and 15° backward.
9. The setting of the driver's seat. To ensure that the operator has a better view during loading operations, the driver's seat is generally placed forward. For articulated forklifts, place them on the front frame as much as possible, and install a roof-guard cab with FOPS/ROPS according to different operating requirements.
10. Walking system. Similar to loaders, there are mechanical transmission (Me), hydraulic shift mechanical transmission (HyC), hydraulic transmission (T/C) and hydrostatic transmission (HYD). The difference is that the full power matching method is selected, and the maximum load is the full-load climbing condition.

Features of four-wheel drive off-road forklift
1. The hydrostatic transmission power is high, and the working condition area is wide, which can save resources and simplify the structure of auxiliary equipment such as heat dissipation and cooling.
2. The closed loop using the combination of variable pump and variable motor realizes automatic stepless regulation, and the diesel engine power is relatively stable, the power utilization rate is the highest, and the whole machine is economical.
3. Using the dual DA control variable system, under compound operating conditions, the speed of the diesel engine decreases, but the pressure of the hydraulic system remains unchanged, so that the traction does not decrease.
4. The overall parameter optimization of the whole machine is completed to the greatest extent, so that it can provide the maximum productivity and the highest economic benefits.
The scale of use of four-wheel drive off-road forklifts
Four-wheel drive cross-country forklifts are mainly used in township construction sites, pipeline laying, oilfield development, mountain forest areas and other outdoor projects, as well as container loading and unloading operations in docks and cargo yards. They are also used for troops to load and unload military materials with the army during wartime.
