How to control the crane risk

The working speed of the crane refers to the speed at which the working mechanism of the crane operates stably under the rated load. The speed of lifting refers to the vertical displacement speed of the rated load under steady state operation of the crane, and the unit is m/min . The operating speed of the cart refers to the speed of the crane with rated load on a horizontal road or track, in m/min . The running speed of the trolley refers to the running speed of the trolley with the rated load on the horizontal track in the steady state. The unit is m/min . The speed of the amplitude is the average linear speed of the horizontal displacement from the maximum amplitude to the minimum amplitude in m/min . Travel speed refers to the smooth running speed of the mobile crane's rated load under the road driving condition, and the unit is km/h . Rotation speed refers to the speed of rotation of the crane around its center of rotation in steady state, in units of r/min .

Risk control; put an end to the absence of certificates or certificates ( driver's licenses, driving licenses, qualification certificates, driver's licenses, and special operation certificates ) to prevent unlicensed personnel from causing injuries due to private driving. The driver of the crane should wear protective clothing to prevent misuse and cause lifting accidents. It is strictly forbidden for crane drivers to take up their posts after going on duty and in poor health to prevent poor physical conditions and cause lifting injuries. When the crane driver concentrates his energy, he must not be allowed to eat snacks, take cell phones, gossip, and smoking to prevent lifting activities, so as to prevent distractions and cause injuries. Lifting crane driver sustained job can not be more than three hours, more than three hours should stop working, the rest were working 12 hours before to prevent poor health, injuries caused by lifting. The crane driver can only operate after clear command signals to prevent lifting accidents. 7) When lifting a heavy object , it is forbidden to hoist in the radius of the boom to prevent lifting accidents. 8) It is forbidden to diagonally pull or lift objects buried in the ground with unknown weight to prevent lifting accidents.

Where there are two sets of main and auxiliary lifting mechanisms, it is not allowed to use the main and auxiliary hooks at the same time to prevent improper operation and damage to the hanging or personal injuries. When lifting the job site is unclear, lifting operations are strictly prohibited to prevent lifting accidents. It is forbidden to exceed the rated load of the crane in case of overturning of the vehicle and personal injury. When lifting a heavier item, the object should be lifted 100mm from the ground. Check whether the brake and safety device of the crane are sensitive and effective. Continue to work under normal conditions. When lifting work, the outriggers should be fully extended, and the vertical cylinders can be fully grounded. If the work site is inclined or soft, use a plate to strengthen the support and improve stability; to prevent the vehicle from overturning after lifting. Truck cranes must receive good legs when moving and parking. When the weight is dropped, the reel rope should retain 3 turns of the safety rope to prevent roll rewinding and lifting accidents. The crane should be stable with the load to prevent the tilting of the cargo caused by the slew of the sling. When rotating, whistle warnings must be given regardless of whether there are people in the surroundings. When lifting or falling heavy objects, crane drivers should implement stable, accurate, safe and reasonable operation equipment. They should prevent pendulum swinging and cause objects to fall and cause lifting accidents. y:Calibri; mso-hansi-font-family:Calibri'>Therefore, the winding of the wire rope must be performed by professional staff to ensure that the entanglement is accurate and the service life of the wire rope is guaranteed.
