Prior to lifting operations, the site must be cleared to avoid any factors that could affect safety. It is essential to check whether the CNC hydraulic plate rolling and bending machine and its surrounding environment meet safety requirements. This includes ensuring the integrity of electrical equipment, the hydraulic system, and the lubrication system, and confirming that fastening screws (caps) are not loose. Verify that the upper and lower molds are in the specified positions, check if the oil pump motor is operating normally, and lubricate according to the lubrication chart. Inspect the oil circuit, oil cups, oil level, and oil quality to ensure they are in good condition.
During Lifting Operations, focus on monitoring the changes in the guy ropes, ground anchors, and lifting points, and fix them promptly to ensure the stability and safety of the equipment. Keep components vertical to avoid overloading and wire rope slippage. This can reduce vibrations and impacts caused by imbalance. When changing the opening of the variable lower mold, ensure no material contacts the lower mold to prevent accidents.
In case of an emergency, such as equipment failure or an accident, quickly initiate the emergency response procedure. This includes stopping operations immediately, shutting down to inspect the cause, and reporting to superiors and relevant departments based on the severity of the emergency.
Ensure the lifting operation road is level and solid, and the slope of the crane parking location does not exceed 2/1000 to prevent equipment from sliding or toppling.
During operation, keep the boom stable, avoid emergency braking or impact vibrations, and avoid driving at full load to reduce vibrations caused by sudden acceleration or deceleration.
Install a vertical light curtain in front of the equipment operation position to prevent personnel from directly touching dangerous parts such as the slider. Additionally, configure fixed protective devices as needed, such as hydraulic locking devices and hydraulic support safety circuits, to enhance safety.
According to safety lifting regulations, the maximum angle of the steel wire rope during lifting should not exceed 120 °, otherwise it is easy to cause the steel wire rope to break; When the angle exceeds 60 °, anti unhooking measures should be taken, and steel wire ropes with lifting rings should be used as much as possible; When flipping the workpiece, use size hooks according to the situation, lift and place gently to avoid direct impact caused by flipping, which may cause damage to the rope or crane, and cause safety issues.
The upper and lower rollers should be lifted using corresponding load-bearing lifting belts. When lifting the lower rollers, they must be tied and lifted to prevent slipping; When lifting the upper roller, in order to ensure the direction of the bearing seat, it is necessary to lift it in front of the bearing seat. Special attention should be paid to cutting the lifting straps at the right angle, and rubber pads should be used at the right angle.
When conducting multiple hoisting operations, a safe distance should be maintained, and operations should be directed by a unified command to prevent mutual interference and collisions.
