The technical parameters of the forklift are used to indicate the structural characteristics and working performance of the forklift. The main technical parameters are: rated lifting capacity, load center distance, maximum lifting height, gantry inclination, maximum running speed, minimum turning radius, minimum ground clearance and wheelbase, track and so on.
1、Rated lifting capacity: The rated lifting capacity of the forklift refers to the maximum weight of the cargo allowed to lift when the distance from the center of gravity of the cargo to the front wall of the fork is not greater than the center distance of the load, expressed in t (tons). When the center of gravity of the cargo on the fork exceeds the specified load center distance, the lifting weight should be reduced accordingly due to the limitation of the longitudinal stability of the forklift.
2、Load center distance: The load center distance refers to the horizontal distance T of the center of gravity to the front wall of the vertical section of the fork when the standard goods are placed on the fork, expressed in mm (mm). 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.
4、Gantry Dip: Gantry Dip is the maximum inclination of the gantry forward or backward relative to its vertical position on a flat, solid ground. The function of the anteversion angle is to facilitate the forking and unloading of the cargo; the function of the reclining angle is to prevent the cargo from slipping off the fork when the forklift is in stock. Generally, the forward tilt angle of the forklift is 3°~6°, and the backward tilt angle is 10°~12°.
5、Maximum lifting speed: The maximum lifting speed of a forklift usually refers to the maximum speed at which the cargo is lifted when the forklift is fully loaded, expressed in m/min (m/min). Increasing the maximum lifting speed can improve the working efficiency, but the lifting speed is too fast, and it is easy to cause damage and machine damage. At present, the maximum lifting speed of domestic forklift trucks has been increased to 20m/min.
6、The maximum driving speed; increasing the driving speed has a great influence on improving the working efficiency of the forklift. For internal combustion forklifts with a lifting capacity of 1t, the maximum driving speed at full load is not less than 17m/min.
7、Minimum turning radius: When the forklift is driving at no speed and running at full speed, the minimum distance between the outermost side and the innermost side of the vehicle body to the turning center is called the minimum outer turning radius Rmin and the minimum inner turning radius rmin. The smaller the minimum outside turning radius, the smaller the floor area required for the forklift to turn and the better the maneuverability.
8、Minimum ground clearance: The minimum ground clearance is the distance from the lowest point of the vehicle body fixed to the ground outside the wheel. It indicates the ability of the forklift to protrude over the ground without collision. The greater the minimum ground clearance, the higher the passability of the forklift.
9、Wheelbase and track: The wheelbase of the forklift refers to the horizontal distance between the centerline of the front and rear axles of the forklift. The track is the distance between the centers of the left and right wheels on the same axis. Increasing the wheelbase is beneficial to the longitudinal stability of the forklift, but increases the length of the body and increases the minimum turning radius. Increasing the wheelbase is beneficial to the lateral stability of the forklift, but it increases the total width of the body and the minimum turning radius.
10、The minimum width of the right angle channel: the minimum width of the right angle channel is the minimum width of the channel intersecting 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、Stacking channel minimum width: The minimum width of the stacking channel is the minimum width of the channel when the forklift is in normal operation.
