Abstract

The present invention is applied to a technique to provide a prompt rescue to a victim in case of an accident on a wind turbine tower. A remote controlled crane is used to carry rescue equipments which automatically follow a climber. Automatic follow up of the rescue equipments to the climber makes rescue gear available to the climber more promptly when required. Thus, the technique significantly increases the survival chances of the victim by limiting the time the victim hangs in harness.

TECHNIQUES FOR INCREASING SAFETY WHILE CLIMBING WIND TURBINES

BACKGROUND

The present invention generally relates to a remote controlled crane and more particularly to a remote controlled crane which automatically follows a climber to provide rescue to a victim in case of an accident on a wind turbine tower.

Normally, safety harnesses are used to climb wind turbines. During climbing the wind turbine there are chances of accidents whereby the victim remains hanging on the safety harness. In such a case, the safety harness constricts the blood flow to the legs of the victim which causes severe problems and even death of the victim. Therefore, a prompt rescue is required to the victim to avoid any such problem.

In the existing practice of rescue in case of an accident in the wind turbine tower, it is difficult to get rescue equipment to the victim quickly. Typically, the rescue equipment is placed in a crane which is operated only from bottom or top of the turbine tower. Therefore, a rescuer needs to climb all the way up or down to operate the crane and bring the equipment to the nearest platform to the victim. Thus, rescue becomes a difficult task. The rescue becomes more difficult if the accident happens near the bottom of the tower and the rescuer is above the victim. In such a situation, the rescuer either needs to climb past the victim to get to the bottom, or climb the entire tower to the top. Climbing past the victim to reach to the bottom is potentially dangerous for the rescuer, while climbing the entire tower to the top takes long time. Further, if the crane with rescue equipment stays close to the climbers, the rescue work is provided much more quickly and with a higher chance of success.

It would be desirable to have a technique to provide a prompt rescue to the victim in case of an accident on a wind turbine tower.

DETAILED DESCRIPTION

 

The present invention proposes a technique which involves a remote controlled crane with follow up logic to provide rescue equipment to a victim in case of an accident on a wind turbine tower. Both the climbers i.e. a victim and a rescuer carry a remote control to...
