For cranes with load when walking

For cranes with load when walking , self propelled pallet jack because the body shaking, boom along the pitch , the rates are constantly changing, but also because of the inertia of the heavy lifting and swinging , hanging oblique form , therefore , from the weight of the load shall not exceed the allowable 70 % solid walking path should be smooth, heavy cranes should be positive in the forward direction , hydraulic hand truck to facilitate the operator to observe and control the weight from the ground shall not be greater than 500mm, and should be well tied rope , slowly. Non- load driving long distances .

non- neutral slide downhill .

When the crane downhill , gravity and magnitude of the crane Hand fixed lift table boom with the slope and, therefore , should be no-load crane walking down the ramp , the uphill elevation should be appropriate to put a small boom , will play when downhill boom elevation appropriate amplification . Neutral downhill slide will result in loss of control accidents, Post lift tables non- neutral slide downhill .

two crane hook pulley should remain vertical.

In order to make a reasonable allocation of loads and synchronous dual action , should lift crane unified command , ride on pallet trucks the action should be coordinated with the load should be allocated on a reasonable , single lifting loads must not exceed the permissible load of 80%. To prevent overloading the lifting process , Hand pallet jacks two crane hook pulley should remain vertical.

When the crane is stopped while still hanging heavy in the air

When the crane is stopped while still hanging heavy in the air ,Electric pallet truck even if the brake pedal is fixed , should foot on the brake pedal , while in case of danger to timely control to ensure the safety of lifting operations and reliable.
9. Hoisting the use of dual job, should be used crane electric platform stacker lifting a similar performance

to prevent cave- hook .

Lifting operations may not have the slightest error , work positioners lifting heavy objects should be hanging slightly off the ground interview , when the weight has been linked to the prison to confirm the reliability and stability of the crane brakes are good , and then continue lifting, in order to detect and eliminate insecurity. In the process of weight lifted , the operator should put his foot on the brake pedal , electric walkie pallet jack pay close attention to lifting heavy objects , to prevent cave- hook .

Implement measures to prevent falling lid

Immediately stop driving, the position of the specified test results, the drive wheel mounting bolt 6 which two books wreck. Residual ri four loose bolts also found a set of worst-case fall accidents can be avoided.Reason 1. Bolt position Quick lift Hand Pallet Truck crane inspection body a little less than the lower part.loose bolts were implemented，Measures 1 additional point inspection record sheet, hand truck dolly check the implementation of education.loose bolts to stop the implementation. Implement measures to prevent falling lid
