introduction: How to brake electric forklift truck 1、For internal combustion forklifts,Apply slow down parking brake when operating。That is, in the process of picking up or unloading goods,The lower the speed of the forklift, the safer。Because of the short distance,And keep the engine running,Drivers tend to slow down with the clutch pedal,When the fork is in place,Press the brake pedal to stop the car。It can be seen that predictive braking is often used in forklift operation,It is to improve operational efficiency,The key to safety。 2、Predictive braking。Predictive braking is

introduction: A few concepts about planetary reducer: series:Number of sets of planetary gears.Because a set of star gears can not meet the larger transmission ratio,Sometimes need2Nested or3Set to meet the requirements of championing a larger gear ratio.Because the number of star gears increased,therefore2Lv OR3The length of the stage reducer will be increased,There will be a decrease in efficiency. Return clearance:Fix the output,The input is rotated clockwise and counterclockwise,Make the input end produce rated torque+-2%Torque hour,Theres a slight angular displacement at the input end of the reducer,This angular displacement is the return clearance.The unit is..."points",Just one degree
