According to statistics, 1 November 2017 construction crane accumulative total sales of 30018 units, compared with 2016 in November 1 - an increase of 13363 units, up 80.2% from a year earlier.With the increasing number of cranes, need drivers also grow, here small make up just to tell everyone about it Small crane When hoisting need to pay attention to those aspects:
-
Small crane driver training must be specially trained and study the relevant operation knowledge, and after examination and appraisal by the relevant departments, hold the rear can mount guard operation, the operating permit in unlicensed driving skills of workers operating small crane.
-
Before hoisting operations, crane driver of inspection is needed, such as: devices are normal condition the main parts, the rope is in line with the safety rules and reliable safety alarm device, hydraulic equipment available is sensitive to normal.Remember to carefully screening potential safety hazard, maximum limit to reduce the possibility of accident.
-
The driver in the operating process must be in close coordination with the commander, to follow instructions operation, according to the provisions of the relevant operation.Do not make operation, in the model is not clear or knowing mistake but refused to carry out instructions.During the hoisting operations, in any case, such as, after receipt of the emergency stop signal must be executed immediately unconditionally, parked informed, after exclusion of factors influencing the safety of may continue to operate the crane for homework.
-
To vertical lifting, in accordance with the relevant provisions in the process of operation in drag has yet to lift an object, so as not to test load cause safety accidents.
-
In the process of lifting operations, in a hurry and at the same time for more than two and operation action, to step by step operation, to avoid safety accident.Boom around the rotation speed is too fast, slow and steady.Remember that an inclined condole, quick lifting, hoisting buried under ground objects and forcibly pull lifting adsorption of the larger area of the ground object.
-
Near the live line work, should pay attention to and keep a safe distance, to increase safety distance when fog had to 1.5 2 times more than normal weather.Through live line below should be ahead of schedule when will boom down, side to hang wires, cause safety accidents.
-
Remember that the table hoisting operation, do not overload operation.As a special case need two crane or lifting the same object at the same time, to obey the instructions of the commander, two small crane lifting speed to maintain consistent, and also have invited to the weight of the lifting heavy objects, no more than 75% of the sum of the two largest crane crane weight.When bound to hoisting rope also want to pay attention to the share the load, make sure to share the load is not more than 80% of the single biggest drop weight of the crane
-
In the process of operation, to keep a certain distance between hook with a pulley, limit time avoid winding wire rope tensile or rear suspension arm.Know the length of the wire rope, ensure the crane arm fully extended to maximum elevation and hook, when reduced to the lowest position of wire rope winding the roller also keep at least more than three circles.
-
Small crane boom elevation to the big fish 30% during operation, to avoid during hoisting load changing the Angle of the boom, and before the lifting load stopped completely forbidden to other actions.
-
During operation, it is strictly prohibited to operation and maintenance, all the maintenance work must be finished before the operation.
-
After forbidden objects will be suspended in the air, rest or shutdown by accident, crane to stop homework must be safe lifting objects placed on the ground.
-
After completion of assignments, hook hanging arm must be placed in accordance with the relevant provisions in the set position, and all the handles are the central place.Appeared in operation after the completion of the boom is still in the extended state, hook is not fixed.
