introduction： Some people only pay attention to the installation and use of the reducer，And the lubrication of the reducer is left behind，In fact, lubrication is also very important and can not be ignored。The following describes how to lubricate the reducer。 1、Under normal conditions the reducer can be lubricated using an oil pool，Keep the oil level in the middle of the oil window，If it is in the case of poor working conditions，Cyclic lubrication can be used if the ambient temperature is high。 2、When refueling, you can unscrew the ventilation cap on the upper part of the frame to directly refueling。It is also necessary to put the frame when the oil is discharged

introduction：Summary of electric forklift classification The electric stacker is a kind of light lifting and stacking equipment for indoor use，Relatively light body，The lever arm of the counterweight is lengthened by the support arm at the front of the body，To balance the load。Because the fulcrum is outside the center of gravity of the load，The counterweight lever is much larger than the load lever，So a smaller counterweight can lift a larger load。Electric stacker with timeless forceEJC 14Take... for example，Rated load1.4Tons of，And self-weight only955kilogram，Vehicle length、Vehicle width、The turning radius is correspondingly smaller，Jungheinrich also has its patented slow button device，Allows slow operation in the upright braking position
