1. Rated lifting capacity: The rated lifting capacity of a forklift refers to the maximum weight of the cargo that is allowed to be lifted when the distance between the center of gravity of the cargo and the front wall of the fork is not greater than the distance between the center of the load, expressed in T (tons). When the center of gravity of the cargo on the fork exceeds the specified load center distance, due to the limitation of the longitudinal stability of the forklift, the lifting weight should be reduced accordingly.

2. Load center distance: Load center distance refers to the horizontal distance T from the center of gravity to the front wall of the vertical section of the fork when standard cargo is placed on the fork, expressed in mm (millimeters). For 1T to 4T forklifts, the specified load center distance is 500mm.

3. Maximum lifting height: The maximum lifting height refers to the vertical distance between the upper surface of the horizontal section of the fork and the horizontal ground where the forklift is located when the forklift is fully loaded on a flat and solid ground and the goods are raised to the highest position.

4. Mast inclination angle: The mast inclination angle refers to the maximum inclination angle of the mast forward or backward relative to the vertical position of an unloaded forklift on a flat and solid ground. The forward inclination angle is to facilitate fork picking and unloading of the goods; the backward inclination angle is to prevent the goods from slipping off the forks when the forklift is running. Generally, the forward inclination angle of the forklift is 3°~6°, and the backward inclination angle is 10°~12°.

5. Maximum lifting speed: The maximum lifting speed of a forklift usually refers to the maximum lifting speed of the goods when the forklift is fully loaded, expressed in m/min (meters per minute). Increasing the maximum lifting speed can improve operation efficiency, but if the lifting speed is too fast, cargo damage and machine damage are prone to accidents. The maximum lifting speed of domestic forklifts has been increased to 20m/min.

6. Maximum travel speed: Increasing the travel speed has a great impact on improving the operating efficiency of the forklift. For an internal combustion forklift with a lifting capacity of 1T, its minimum travel speed when fully loaded is not less than 17m/min.

7. Minimum turning radius: When the forklift is driving at a low speed without load and turning with a full steering wheel, the minimum distance from the outermost and innermost sides of the vehicle body to the turning center is called the minimum outside turning radius Rmin and the minimum inside turning radius rmin. . The smaller the minimum outside turning radius, the smaller the ground area required for the forklift to turn and the better the maneuverability.

8. Minimum ground clearance: The minimum ground clearance refers to the distance from the lowest point fixed on the vehicle body to the ground outside the wheels. It indicates the ability of the forklift to cross the ground raised obstacles without collision. The greater the minimum ground clearance, the higher the passability of the forklift.

9. Wheelbase and wheelbase: Forklift wheelbase refers to the horizontal distance between the centerline of the front and rear axles of the forklift. Wheelbase refers to the distance between the center of the left and right wheels on the same axis. Increasing the wheelbase is conducive to the longitudinal stability of the forklift, but it increases the length of the body and the minimum turning radius. Increasing the wheelbase is beneficial to the lateral stability of the forklift, but it will increase the overall width of the vehicle body and the minimum turning radius.

10. The minimum width of the right-angle channel: The minimum width of the right-angle channel refers to the minimum width of the channel that intersects at right angles for the forklift to travel back and forth. Expressed in mm. Generally, the smaller the minimum width of the right-angle channel, the better the performance.

11. The minimum width of the stacking channel: the minimum width of the stacking channel is the minimum width of the channel when the forklift is in normal operation.
