Hydropower Gantry Crane

Hydropower Gantry Crane

Each industry has a different requirement, which is why the cranes used for each industry is also normally different. As the name suggests, a hydropower gantry crane is normally used in the hydropower related industry, such as a hydropower station. Whether you are looking at large scale supply or drainage of water, conserving water or even hydropower engineering, this is the kind of crane that you will need. The most common use of a hydropower gantry crane is at a hydropower station, where the crane will assist with the opening and closing of the gate, clean up rivers or other similar water bodies and also to transport maintenance and repair equipment.

The lifting capacity of a hydropower gantry crane is normally between 80 to 500 tons, but because the working level is on the lower side, the span is smaller (normally between 8 to 16 metres). In addition, the travelling speed is also on the lower side as is the lifting capacity.

The hydropower gantry crane is actually a light work system, but there are versions which can work at a mid-level system too. This type of crane would be most suitable for purposes such as lifting gates, when ships have to pass through. A hydropower gantry crane consists of a gantry frame, a main trolley, the operating mechanism, slewing hoisting and many a times, a special spreader. What is interesting about this kind of crane is that there are no free hanging weights, rather the weights move or rotate around the gate pillar and often, down the side of the gate slot.

The lifting capacity of a hydropower gantry crane is normally between 80 to 500 tons, but because the working level is on the lower side, the span is smaller (normally between 8 to 16 metres). In addition, the travelling speed is also on the lower side as is the lifting capacity.

Here are some of the types of hydropower gantry crane that you can get:

  • Spillway gate gantry crane – This is an upper spillway gate crane that lifts the gates. This type of crane can clean the debris that tends to accumulate in front of the gate. This is also the type of crane that is used for maintaining the various equipment, that can be found on the dams. However, it is the lower spillway gate crane that handles the task of lifting and lowering the gates.
  • Turbine hall crane – The turbine bridge crane is the crane that is most often used to mount the turbine and other such powerhouse equipment. Because of the weight and often cumbersome nature of these equipment, a crane becomes necessary for movement. This type of crane can also find usage in general maintenance.

The hydropower gantry crane also finds use in maintenance shop hoists and jibs, the wind mill hoist, intake gate gantry and draft rube gantry cranes.
