Crane is a special hoisting equipment, the operator must have safety awareness, in strict accordance with the operating procedures, to avoid improper operation and cause of the accident, so the usual work, must pay special attention to.Here families step science technology to you about the small crane safety operating guidelines:
-
Must be inspected before use crane crane boom, each pin, bolt, cable connectors have become loose, fall off phenomenon.If defects are found, should be repaired before work.The crane should be set aside for fire extinguisher.In case of leakage, fire should be immediately cut off power supply, and immediately stop processing.
-
Crane to the no-load test run after launch, when hoisting, listen to the command signal, the driver in close coordination with the command to the operating command signal, when the signal is unknown or unclear, or may cause accident, should suspend operation, you may not drive/mesh or lifting.
-
Job it is forbidden to throw leg operated valve, if need to adjust the leg, must be conducted in the absence of load, and the arm is transferred to ahead or behind, found in homework leg sinking, the abnormal phenomenon such as crane tilt, should immediately put down the heavy weights, adjust the rear can work.
-
Crane for lifting the workpiece, when walking load shall not exceed the allowed the weight of the crane, artifacts should be in front of the crane, shall not exceed 500 mm from the ground, for long objects to prevent swinging, driving slowly.
-
Crane lifting the rated load or close to the rated load, the weight from the ground up to 200 ~ 200 mm should be stop, after checking the stability of the crane, the reliability of the brake, the weight of colligation of balance, soundness is confirmed after, can continue to ascend.
-
Crane hoisting groove and foundation pit should be standing on a flat solid and maintain proper distance on the ground.If ground soft or not normally, leveling should be strengthened, and padded with a tie, should be in the lower leg floor to the fuselage top up stow-wood, and maintain a level.
-
Crane driver drunk not operation, during operation and others to talk, laugh, must concentrate, so as to avoid the accident.
-
Crane operator to pay attention and check whether lifting objects binding rope buckle is rigid, all rigging and fixture must have sufficient strength, found to have damage, cannot be used reluctantly.
-
Drivers must clearly be lifting the weight of things, no suspension inclined condole, do not allow the hoisting crane crane, lifting heavy objects are not allowed to move the car position.
-
When at capacity or close to full load hoisting, forbidden land arm or two lifting movement at the same time.Generally when hoisting, and may not be on boom and arm, if needed, should comply with the safety requirements of the lifting chart before operation.
-
Lifting objects should be set to slip rope, lifting speed wants even, smooth operation, fast and slow and sudden braking.For the operation, must be crane stopped after reversing operation, sudden changes of direction is prohibited.
-
When lifting, forbid to horizontal dragging objects or inclined hoisting, it is forbidden to lifting the pull of the buried condition of unknown objects or condensation on the ground, frozen in the ice.
-
Rotary crane on things, should be slow, the speed should not exceed the specified value.Banned in slope lifting heavy rotation.
-
Ban on lifting objects, people, not the crane used as transport personnel.Are not allowed to be in when lifting boom or lift weights under standing, lifting vehicle driving indoor is not allowed to someone, it is forbidden to weight lifting the car cabin.
-
Empty load running, hook with ground spacing shall not be less than 2 meters, loading operation, the weight must be higher than 0.5 meters running route as the highest obstacles.
-
Lifting heavy weights are strictly forbidden to free fall, hand or foot brake control slow decline, wire rope on the drum to order, when the hook in the lowest position, should keep at least four laps wire rope drum.Lifting of the ban by hand touch the wire rope and pulley.
-
Crane when walking on the ramp, humping glide is prohibited.Walk to the reversing, should be carried out after the crane to stop.
-
When two or more machine lifting crane, there must be a unified command, the movement coordinated, hoisting should be reasonable allocation, shall not exceed 80% of the single machine allows the hoisting.
-
If a fault occurs in the process of hoisting crane, should immediately stop the hoisting, and take measures to hang down, stop after the mechanic for repair, please it is strictly prohibited in the operation of maintenance and repair work.
-
Stop work, must stop brake.After work, hook and boom should be prescribed in the appropriate position.All control handle should be in zero, cut off power and close the door locked.
-
Lifting lever don't pull too tight, in order to avoid emergencies, lever pull don't come back, from crane against accidents.
-
When lifting, push the crane hook up after first from the pedals, when hook commutator first handle on the hook position, can automatically under the pedal.
-
When crane hoisting heavy rotation, the movement wants slow to prevent lifting swing, make crane askew, and shall not stand under the crane arm when lifting.
-
When lifting heavy objects, not climb the pole operation, if have to climb the pole when lifting objects should be put down to climb the pole, and then lifting, hoisting accident so as not to.
-
Strictly abide by the "ten don't hanging" namely: command signal is unknown or illegal orders not mourn;Overload lifting;The work-piece not firm not hanging;"Is someone or put things not hung;Safety device is ineffective not mourn;
-
Artifacts buried not mourn;Light the dark can't see don't mourn;Suspension artifacts not hanging;Edges and objects without measures don't mourn;Oxygen cylinder, acetylene generator with inflammable and explosive dangerous goods not hanging, etc.
-
The heavy rain, snow, heavy fog weather or the temperature below 20 ℃ (including - 20 ℃) and instantaneous maximum wind speed of more than 10 m/s, should stop lifting operations.Strong winds, mobile crane should be parked in the hiding place;Crawler crane should be put on in the longitudinal direction and crawler, machine back to the wind, and the lift arm fell to the ground or the hook fell to the ground to the object, locking slewing brake.
-
Mobile crane after the completion of the work, the balance of leg and slewing derrick shall not simultaneously.Should first slewing derrick legs to walk again payments.
-
In case of traffic accident, the parties concerned shall protect the scene of the accident, immediately report to the police department, and report to rent unit and corporate security department accident after the basic situation and the casualties and property losses.Actively cooperate with public security traffic police department for accident treatment.
-
Hoisting accident, the parties should protect the scene of the accident and take swift measures to rescue the wounded and equipment, and immediately to rent unit and engineering department of the company and their department report accidents through the basic situation and the casualties and property losses.Actively cooperate with the security department for the investigation of the accidents.
