Bridge Crane and Overhead crane on a ski hill.

Bridge Crane and Overhead Crane Opportunity:

Demag Cranes & Components 10 Ton Wire Rope hoist on Bridge cranes for one of the highest crane application in the world. The bridge Crane is used for preventive maintenance on an innovative snowmaking installation. The “Snowmaker”, supplied by the company IDE Technologies Ltd., produces 3300 cubic feet of artificial snow every day, in high quality and without any chemical additives. Overhead cranes can help people to ski.

The Solution

The Bridge crane Wire Rope Hoist  is equipped with 2 speed lift, low headroom under running Bridge crane trolley with a top running single girder beam crane configuration. The Wire Rope Hoist requirement was 2 speed lift, but the other travel motions are equipped with variable speed for ease when transporting material.

• The Overhead Bridge Crane included the standard travel VFC features, allowing trolley and bridge infinitely variable speed motions, which provided the operator the precision required.
• The Bridge Crane lift requirement was close headroom as seen in the above photo.
• The trolley and bridge on the Overhead crane is able to change speed as required by the operator.  The travel on the bridge and trolley are infinitely adjustable by the operator. This allows motions to be fine-tuned to correspond with each individual requirement. The operator can adjust the speed and the acceleration of the bridge by changing the pressure exerted on the button of the control station. This allows the operator to make adjustments depending on the application requirement.
• Four-position travel limit switch is standard on the hoist, but optional crane travel limit switches were supplied to stop the trolley and the bridge precisely as required by the customer for the application.

Wrap Up

The operators have been very pleased with the ease of use of the crane and the hoist.

Safety was improvement. Continuous reliable operation.
