Forklift basic technical parameters and how to prevent oil leakage
Posted: Nov 26th, '24, 03:11
The technical parameters of forkliftare used to indicate the layout characteristics and operation functions of forklift. The primary technical parameters are: additional lifting weight, load spacing, lifting height, gantry Angle, travel speed, turning radius, ground clearance and wheelbase, wheel base, etc. (Most of the parameters here are the parameters of the mounted forklift truck, some parameters of the electric stroller, electric truck do not).
1, additional lifting weight: the extra lifting weight of the forkliftrefers to the space between the center of gravity of the goods and the front wall of the fork is not greater than the spacing in the load, which is indicated by t (ton). When the center of gravity of the goods on the fork exceeds the regular load spacing, the lifting weight should be reduced accordingly because of the constraints of the longitudinal stability of the forklift.
2, the load distance: the load distance refers to the horizontal interval of the front wall of the center of gravity to the straight section of the fork when the standardized goods are placed on the fork, which is indicated by mm(mm). About 1t forklifttruck the regular load spacing is 500mm.
3. Lifting height: Lifting height refers to the straight interval between the upper surface of the horizontal section of the fork and the ground when the forkliftis fully loaded and the goods rise to the highest position on a flat and solid ground.
4, gantry Angle: gantry Angle refers to the unloaded forklift on the flat and solid ground, gantry relative to its straight direction forward or backward maximum inclination Angle. The effect of the front Angle is to facilitate the forkliftand unloading of goods; The effect of the rear Angle is to prevent the goods from slipping off the fork when the forklift is carrying freight. Usually, the front inclination Angle of the forkliftis 3°~6°, and the rear inclination Angle is 10° ~ 12°.
5, lifting speed: forkliftlifting speed usually refers to the speed of lifting goods when the forkliftis fully loaded, which is indicated in m/min (m/min). It can improve the working power, but the lifting speed is too fast, and it is easy to cause cargo damage and machine damage.
6, travel speed; The progressive speed has a great influence on the working power of the progressive forklift. When paired with an internal combustion forkliftwith a starting weight of 1t, the traveling speed is not less than 17m/min when fully loaded.
7. Turning radius: When the forkliftis traveling at a low speed without load and turning with the steering wheel full, the minimum interval between the outermost and innermost parts of the vehicle body and the middle of the turn is called the minimum outer turning radius outside Rmin and the minimum inner turning radius inside rmin. The smaller the minimum outside turning radius, the smaller the ground area required for forklift turning, and the better the maneuverability.
8, the ground gap: the ground gap refers to the distance from the lowest point fixed on the body to the ground outside the wheel, which indicates the ability of the forklift to skip the raised obstacles on the ground without bumping. The larger the clearance from the ground, the higher the passability of the forklift.
9, wheelbase and wheel base: forklift wheelbase refers to the horizontal interval of the middle line of the front and rear axle of the forklift. Wheelbase is the interval between the left and right wheels on the same axis. The increase of wheelbase is beneficial to the longitudinal stability of forklift, but the length of the body is increased, and the minimum turning radius is increased. Increasing the wheel base is beneficial to the lateral stability of the forklifttruck, but it will increase the total body width and minimum turning radius.
How does a forklift prevent oil leakage?
(1) Careful disposal of various liners. Such as oil pan or valve cover, because the touch area is large, it is not easy to compact, and it simply forms oil leakage. Oil leakage in the crankshaft rear oil seal will enter the clutch, which will not only cost oil but also make the clutch plate stain and slip and burn out.
(2) Tighten the nuts according to the repair standard. Too loose pressure will not tighten the liner will leak oil; Too tight will cause the metal around the screw hole to protrude or the thread to slip, resulting in oil leakage. If the oil drain plug of the oil pan (shell) is not tightened or loosened, a lot of oil is simply lost, and then the incident of "burning tile holding shaft" occurs.
(3) Replace the failed oil seal in time. Improper oil seal device, shaft journal and oil seal cutting edge is not the same heart, it is simple because of the swing and throw oil; After long-term use, some will lose elasticity due to rubber aging, seal lip damage and cracking or self-tightening spring failure, will lose the sealing oil effect, should be modified or replaced according to the standard qualified parts.
(4) Timely replacement of severely worn parts. For example, the cylinder liner, piston, and piston ring wear to a certain extent, which will cause the high-pressure gas in the incineration chamber to escape into the crankcase.
(5) Timely repair of the main bearing. When the cooperation gap between the main bearing and the journal is too large, the front and rear oil seals will lose their sealing due to the impact effect of the crankshaft, resulting in oil leakage from the crankshaft head, or oil seepage into the clutch, and then contaminating the friction plate resulting in skidding and operation failure.
(6) Prevent blocking of check valve and air vent valve. This kind of valve hole is easy to cause the temperature and pressure in the case to increase, the piston movement resistance, the fuel consumption to increase, oil and gas to fill the entire space, and the smooth oil cost addition and replacement cycle to shorten. Because of the effect of the pressure difference in the case, the oil leakage is often caused by the thin seal. Should regularly check, dredge, clean, to adhere to the check valve, air valve dredge.
(7) Properly solve the sealing of all kinds of tubing joints. The pipe connecting nut is often disassembled, simply because the slip wire is broken and loose, so that the accuracy of the two joints is poor, because the center line of the cone is not coincident and the touch is bad, because the taper is not the same and does not match, etc., resulting in oil leakage. Tighten and compact the nut to ensure the seal after the grinding pipe joint is sealed with the flare or after the thin copper leather is clamped to the two cones.
(8) Prevent the wheel from swinging oil. When there is too much smooth grease in the hub bearing and cavity, or improper hub oil seal device, poor quality, aging failure and frequent braking cause the hub temperature to be too high and the half shaft nut to loose, it will cause the hub to throw oil. The cavity smooth method should be selected (that is, properly smooth), the vent hole should be dredge, the brake should be used reasonably, the high-quality accessories should be strictly selected, and the devices and adjustments should be made according to technical standards.
