For everyone
Safety knowledge of lifting equipment
(the first six knowledge issues were incorporated into the safe production months series)
Let's do a safe work together
Let's come and see
Truck, crane
1. Pre-use inspection of the technical condition of the departments, focusing on operational devices, hydraulic devices and wire lines
2. Be careful during operations to inspect the surrounding environment and to prohibit suspension operations near the high pressure line
3. Prohibition of over-heavy suspensions, which are first carried by super-heavy objects from the ground to about 10 cm to check stability and the safety and effectiveness of the brakes, and to confirm and then perform the suspension
4. The car is not allowed to hang the crane
Five or two cranes shall be accompanied by a unified command, the load of the crane shall be distributed equally and the load shall not exceed 80 per cent of the maximum starting weight per vehicle
6. The suspension during the construction is stopped and the suspension must be placed on the ground before the operation can be stopped。
Tower crane
1. Pre-inspection tower crane safety attachments, wire ropes, slider groups, rotation systems, after confirmation of safety before they can be used
2. Work under high-voltage transmission lines shall be avoided to the extent possible and shall be subject to exclusive supervision while operating under high-voltage lines, together with external electrical protection
3. The lifting of the lifting weight shall be preceded by a test suspension, which shall meet the requirements for the suspension before the operation is carried out
4. The free movement of lifting weights is strictly prohibited and the use of hand or foot brakes is slowly declining
5. The distance between the two towers and the suspension shall not be less than 5 m while the two towers are in operation
6. Operation of the lifting operation shall be carried out in strict compliance with the safety protocol for the lifting of towers, and no person shall remain below the lifting arm, no crane crew shall be suspended, no wind or fog above class 6 shall be encountered, and no suspension shall be prohibited in heavy rain
7. Upon completion of work, maintenance, overhaul should be performed in a timely manner。
Bridge crane
1. The mechanical equipment, electrical components and protective safety devices shall be carefully checked prior to the operation, and a test suspension shall be carried out prior to their loading and shall not become operational until all normal conditions have been confirmed
2. The operation shall be subject to signal command and no lifting material shall be suspended from the air at the time the operation is interrupted
3. The suspension is prohibited from exceeding or staying over a person's head
4. When the hook is not loaded, the height shall be increased by more than one person
5. When hung, the angle between the hanging ropes shall not be less than 120°, avoiding overstretching
Inspections and repairs are not permitted at the start-up and replacement, and maintenance should be carried out under exclusive supervision and with the cooperation of the repair
7. On completion of the operation, the lock-in should be locked, and wind and bad weather above the pre-class 6 level cannot be forced to operate。
Electric pickles
Pre-use confirmation of the reliability of brakes, limitrs, suspension of objects after the upper and lower limit block adjustment, and prohibition of lifting objects in excess of their assigned load
2. Power should be cut prior to repair and repair and must be repaired and inspected in an empty state
3. The suspension is prohibited from exceeding or staying over a person's head
4. During the suspension, it is prohibited to be hung on the sides of a hanging object or on the sides
5. An electron thallium, with no drop limit, and when the hook is in the lowest position, the steel cord on the roller must be guaranteed a two-fold radius
6. The operator must stand on the reverse side of the direction of the reverse, confirming that there are no other operators in the direction of the reversal。
