A comprehensive inspection before starting the equipment is the basis for ensuring safe operation. The operator needs to confirm the status of each component of the equipment through visual and manual inspection. First, check whether the tire pressure meets the specified standards (usually 0.6-0.8MPa), ensure that the support legs are not deformed and the hydraulic system is not leaking. Verify whether the battery power is sufficient through the control panel. It is recommended that the remaining power is not less than 30%. At the same time, test the response speed of the emergency brake device to ensure that it is effectively started within 0.5 seconds. Pay special attention to the locking mechanism of the platform guardrail to confirm that it can still maintain a rigid connection when carrying a rated load of 300kg to prevent accidents.
The planning of the operation area should follow the principle of three-dimensional space management. Taking a large storage center as an example, before operation, it is necessary to obtain the shelf layout data through the warehouse management system (WMS) to calculate the minimum safe distance between the equipment movement path and obstacles. It is recommended that the horizontal spacing is ≥1.2m and the vertical spacing is ≥2.5m. When setting reflective warning tape on the ground, the maximum extension radius of the equipment (such as the 2.7m working radius of the JLG 38AM model) must be considered to ensure that personnel passage and equipment operation do not interfere with each other and reduce safety hazards.
All parameters need to be precisely controlled during the equipment installation phase. When adjusting the support legs, a torque wrench should be used to ensure that the preload force of each leg reaches 200N·m. The platform angle should be adjusted in conjunction with a digital level to ensure that the inclination of the working surface is controlled within the range of ±0.5°. When passing through a standard door opening (0.9m×2.1m), the equipment needs to be folded to the minimum size (such as the 0.74m width of Genie AWP-20S) and the minimum passing height of 1.98m should be maintained to ensure the safe passage of the equipment.
When performing rising operations, the principle of graded loading must be followed. When starting for the first time, an empty load test should be performed first to observe whether the platform rising speed is stable at 0.1m/s. When loading cargo, the "three-time loading method" is used for gradual loading: the first load is to 30% of the total weight to check the deformation of each connector; the second load is to 60% to verify the pressure stability of the hydraulic system; when finally loaded to full load, continuous observation for 10 minutes is required to ensure that there is no abnormal vibration. In the actual application of a cold chain warehouse, the operator successfully avoided the equipment tilting accident caused by cargo overloading through this method, ensuring the safety and stability of the operation.
A multi-dimensional monitoring system needs to be established for dynamic monitoring during the operation. Operators need to wear smart safety helmets to monitor key parameters such as heart rate (≤120 times/minute) and ambient temperature (-20℃~50℃) in real time. The platform control system should integrate vibration sensors, and automatically trigger alarms when the vibration acceleration exceeds 0.5g. During the maintenance operation of a certain automobile manufacturer, the operator discovered the cracks in the base of the equipment in advance through the system, took timely measures, and avoided potential major safety accidents.
In the descending operation, the "three-stage deceleration" principle should be followed. When the push around vertical lifts is 0.5m away from the ground, the buffer mode is started and the speed is reduced to 0.05m/s; after contacting the ground, it is immediately switched to the support mode to release the hydraulic pressure; finally, the platform position is fixed by a mechanical locking device. This operation process has been effectively applied in a hospital operating room renovation project, ensuring the non-destructive handling of precision medical equipment and greatly improving the safety and efficiency of the operation.
