Waste Handling Cranes

Cranes play a crucial role in modern incineration plants. It is important that the continuous material handling system, from the arrival of the waste to separation and incineration, is not threatened. If the cranes stop, the whole process is in danger. Key factors in specifying waste-to-energy cranes are the total burning capacity of the incinerators, the layout of the handling area, the type of waste, and the time it takes to receive and process the waste. To achieve high efficiency, the waste should be mixed thoroughly.
Normally, there are two waste handling cranes above the waste-pit, one of which is a backup. The primary crane undertakes the main operating functions whilst the other is being serviced
All are prime concerns for WTE operators using bucket cranes to move waste. Add minimal time available for weekly maintenance and infrequent outages for major repairs, and you have a real challenge for operators who need to keep their lifting equipment running.

Konecranes’ WTE crane technology is designed to meet this challenge head-on.

Important components like hoisting trolleys, drives and buckets are engineered to reduce maintenance requirements. More than 10 years ago, Konecranes introduced an integrated rope/cable drum. The vertical power cable for the bucket is wound onto the rope drum and is driven by the hoisting machinery. With this unique solution, savings in maintenance costs are substantial.

Our proprietary DynA Load Control Technologies manage critical crane functions to reduce structural stress, increase efficiency and prolong equipment life. DynAPilot load sway control minimizes load sway from bridge and trolley motions, reducing collisions between the bucket and the pit walls or hopper, and preventing equipment damage. Sway control increases operator
confidence, reduces training time and allows the crane to operate to its full potential.
Konecranes’ approach to minimizing downtime is to include features that reduce the need for maintenance, and to engineer cranes to be easier and faster to maintain during planned outages. Here are only a few of the many maintenance reducing features Konecranes includes in its WTE cranes:
