Crane operation commonsense

Overhead crane is an industrial lifting machinery with higher requirements on its operation safety parameters. We provide you with some operational rules well recognized by our crane engineers for your business and crane operator reference. The crane operation commonsense is as follows:

Generally, the crane operation commonsense includes three parts, which are crane pre-operation period, crane operation period, and crane operation finishing period.

Crane operation commonsense rules that the operators should follow

  • Since overhead cranes as a heavy-duty lifting equipment, often bear large duty materials, different parts of the crane, such as the electrical parts and safety systems may suffer loosen or broken, when starting operating the crane, operators shall check every part of the crane seriously, for safety operation sake.
  • Please check the joints of the crane steel wire rope, whether it is in line with the rules or not.
  • Please check whether the fuel, lubricating oil, hydraulic oil and cooling water are enough when operating the crane.
  • Please check the crane base, whether it is loose or not, if so, please use wood or soil blocks supporting the crane feet.
  • Please check the surrounding working environment, whether it is fit for the crane working or not.
  • Please check the loading materials and their weights, avoid overloading.
  • Please leave a safety room between the lifting materials and the overhead bridge crane.
  • Rules you should care when operators operating the bridge overhead crane
  • When the overhead bridge crane is working, please ring the crane alarm, and confirm the commanding signal.

  • Only operators are permitted to step into the signal area.
  • Crane operators must strictly follow the crane commanding signal rules, any kind of alarm signals heard, the operator shall stop the crane immediately.
  • Please locking the crane’s drums when the lifting materials need a long stay in the sky. When the crane working stops, the please materials shall not be suspended on the sky.
  • When there are people in the crane working area, please ring the alarm, let them off the working area. And the lifting distance shall keep in a limit.
  • When two overhead cranes hoist the same materials, there must have professional commanders to command the operation. And the weights of the lifting materials shall never overpass 75% of the entire crane weight.
  • Free landing operations can only be used when lowering the hook or when the suspended load is less than 30% of the load. It is forbidden to apply emergency braking in a free fall.
  • In strict accordance with the requirements of the load table, prohibit overload.
  • Swing operation, do not emergency stop, to prevent violent swinging objects dangerously. When not turning, the brake will be locked.
  • When the main and auxiliary arms are all extended, the arm angle shall not be less than the minimum angle specified in the instructions for use in order to avoid the accident of overturning of the vehicle.
  • When driving near the encounter, the crane speed should be slow. Replacing the scene with a brake instead of parking, stop instead of stop switch, emergency switch instead of an ordinary switch.
  • When lifting a heavy tonnage object, it should be slightly off the ground to test hanging, confirm the hanging steady, good braking, and then increased, slow operation. Do not operate three control handles at the same time.
  • When the operation due to sudden failure caused hanging slippage, you must take urgent measures to no one landed.

Commonsense rules you should follow the crane working

  • Fully retract the boom, and placed on the bracket, lifting the hook and fixed according to regulations, brake turntable.
  • Strict compliance with the regulations to recover the legs and fixed.
  • Place the control handle in the “0” position to turn off the power.

Crane inspection and management system

Crane use units should always use the lifting machinery inspection and maintenance, and to develop a regular inspection management system, including daily inspection, weekly inspection, monthly inspection, annual inspection, the crane dynamic monitoring, there are any anomalies at any time Found that timely processing, in order to protect the safe operation of lifting machinery.

Daily Overhead Crane Inspection

The driver is responsible for the routine operation of the maintenance project, the main contents of cleaning, lubrication transmission parts, adjustment and fastening work. By running test security device sensitive reliability, monitor whether there is abnormal sound during operation.

Weekly Crane Inspection

It is carried out by service technicians and drivers. Except for the items for daily inspection, the main contents are the appearance inspection, the safety status of hooks, pick-up devices, and wire ropes, the sensitivity and reliability of brakes, clutches, and emergency alarm devices. Observe the existence of abnormal transmission parts noise, and overheating.

Crane Monthly Inspection

The equipment safety management department shall organize the inspection and carry out the joint inspection with the relevant department personnel. In addition to the contents of the inspection, the inspection shall be carried out on the power system, hoisting mechanism, slewing mechanism, running mechanism and hydraulic system of the hoisting machinery, deformation, cracks, corrosion of parts, the electrical control system, check the feeder, controller, overload protection, safety protection device is reliable. Through the test run to check the crane leakage, pressure, temperature, vibration, noise and other causes of fault symptoms. After observing the structure of the crane, support, transmission sub-state subjective test to understand the status of the whole crane control technology, check to determine the anomalies of the source of the fault.

Crane Annual Inspection

The unit leaders organize equipment safety management department heads, together with the relevant departments, in addition to the monthly inspection project, the main technical parameters of lifting machinery testing, reliability testing, through the detection equipment, lifting machinery, moving parts of the work organization of the wear and tear of the metal structure of the weld, test flaw detection, safety devices and components through the test, the operation of lifting equipment to evaluate the technical conditions. Arrange overhaul, renovation, update plan. Learn more, you can also focus on stocking hanging with.

The above are some crane operation and inspection commonsense just for your business safety reference, any detailed information you need, welcome contact us.
