Hazard and Precautions of Remote operated Lifting Machine


Hazards of Remotely operated Lifting Machine

  1. As direction (EWNS) are mentioned on the remote operator is likely to be confused.
  2. Chances of accidents in case wrong movement of direction are possible.
  3. As the operator is operating from the ground, his attention is deviated by the co-worker resulting in the accident.
  4. The person not trained in crane operation also tends to operate the crane, as remote (pendant) is easily accessible.
  5. In case the “push button” or lever gear is pressed by mistake, crane motion may start automatically.
  6. The operator may lock the motion by mechanical means in order to avoid holding by operating the push button/lever.
  7. The motion of the crane is activated by radiofrequency. Interference by other radio frequency may move the crane automatically and cause a dangerous situation.
  8. In case of the emergency main switch is not easily accessible. The main switch of DSL may be far away.

Advantages of Remote operated Lifting Machines

  1. The operator is not required to climb on the lifting machine.
  2. The operator can operate the crane close to the load, this gives more accuracy and precision in handling.
  3. Communication between the operator and attendant (slinger) is better. Hand signaling may not be required, verbal communication is possible.
  4. Operation of the crane is easier.
  5. For smaller lifting, the work of slinger (attendant) may be carried out by the operator himself.
  6. Attendant (slinger) or any other person can easily be trained for crane operation.
  7. No chance of electrical shock as it is completely isolated from high voltage.

The disadvantage of Remote operated Lifting Machines

  1. As the remote works on radio frequency operator may operate the crane from any place. He may not be moving close with the load.
  2. Crane remains unattended, as the operator is not close to the crane. Any abnormality like noise, vibration, loose part, lubrication, is not noticed regularly.
  3. Maintenance person operator is required to check the crane separately, regular (daily) inspection by the operator may not be possible.
  4. In case of operating from the ground, the operator doesn’t get the overall view of complete scene, e.g. obstruction in the part of a moving crane.
  5. The main switch in the control cabin is not accessible.
  6. License is required for radio frequency used for remote control.
