The operation of the lifting platform is designed as a fully automatic operation mode. Press the corresponding button on the control box to realize the corresponding action, and stop automatically after reaching the working height. These functions are realized by AC contactor, travel switch and other electrical appliances.
Precautions for operation and use of lifting platform
If conditions permit, special platform operators shall be provided. Precautions for rail elevator operator when pressing the button:
A. whether the goods are placed in the center of the workbench or not, relevant personnel shall be urged to adjust
B. press the button, the workbench has corresponding action, or immediately press the "stop" button, check whether the power line is lack of phase, so as to avoid burning the motor
Precautions for the operator of guide rail elevator during platform lifting:
A. observe the hydraulic oil circuit for oil leakage
B. is there any abnormal noise in the rotating parts? Do the corresponding treatment. Replace the worn parts in time
C. check whether the hydraulic pump has abnormal noise. If so, it should be dealt with in a timely manner
In case of failure or abnormal condition of lifting platform, it shall be stopped immediately. It can be put into use again after eliminating faults and accident hidden dangers. The equipment maintenance technicians shall earnestly perform the safety responsibilities. For the lifting platform equipment with potential safety hazards, the lift shall require the installation unit and the user to work together, and remove them specially
The hidden danger investigation shall be carried out in an all-round way: the construction unit shall be responsible for finding out the detection subject of hidden danger investigation of the lifting platform, continuously strengthening the daily inspection and regular inspection, and must carefully check the steel structure, safety protection device, device and transmission device of the electrical lifting platform; the user shall arrange special personnel to operate the lifting platform, and formulate the lifting platform for the unit. Details and safety precautions and hang in a prominent position. Operators shall be trained and assessed by the legal management department, and can only be engaged in platform operation after obtaining certificates
Before working every day, the driver shall carefully check whether the electrical system, hydraulic elevator system and mechanical system of the platform are normal, and carry out multiple tests on the platform without loading, check whether there are faults and abnormal phenomena, and pay attention to whether the air conditioner has obvious abnormal clearance. Platform platform parking station accuracy
Before work, the driver locks the movable doors at both ends of the fence, and then rings the doorbell to start work. It is forbidden to work when the movable gate of the fence is opened. The emergency stop switch can be used to stop the platform under special circumstances, but it is prohibited to use the emergency stop switch to stop the platform during normal operation.
The driver shall be responsible for supervising the uniform distribution of the goods transported on the platform, preventing the unbalanced goods as far as possible, and forbidding overload operation. The platform lifting platform shall not carry inflammable and explosive dangerous goods, and climbing and artificial shaking are strictly prohibited.
Maintenance of hydraulic elevator:
1. Check the brake of each mechanism, regularly check and adjust the clearance, ensure the action is flexible and reliable, and there should be no dirt on the friction surface. If there is any dirt, first wash it with gasoline or thinner;
2. Lubrication and hydraulic oil of gearbox, gearbox, external meshing gear and other parts shall be carried out according to the requirements of lubrication table
3. Pay attention to check whether there are broken wires and loose strands in each part of the wire rope. If it exceeds the requirements, it must be replaced immediately
4. Be sure to check the connection of each part. If loose, tighten
5. Check whether the operation of each mechanism is normal and whether there is noise. If any fault is found, it must be eliminated in time
6. Check all wires and cables for damage and replace damaged parts in time
7. When the motor overheats, it shall be shut down in time and continue to operate after troubleshooting. Motor bearings shall be well lubricated
8. The contact surface of each part of the brush shall be kept clean, and the brush pressure shall be adjusted so that the contact area is not less than 50%
9. The control box and configuration box shall be kept clean, and the dust on the electrical equipment shall be cleaned in time
10. The contact point of the travel switch of the lifting platform safety device must be firm, and the arc pit shall be polished in time.
