General Description
Wheel Bucket Dredger with full hydraulic control, dismantled and re-assemble easily, suitable for inland waterway dredging, ditches, and reservoir dredging operations.
The whole ship adopts a hydraulic and centralized control system, consists of three pontoons. dismantled type cabin. equipped with anchor boom,trolley and other devices. Auto lubrication device for cutter ensures long life, independent positioning metal floating ring Seal.
Equipment Advantages
Powerful cutting performance
Our Bucket Wheel Dredger have excellent cutting properties, a constant dredging output in both directions of swing, and the almost complete absence of blockage ensure high production.
More production & more safty
larger debris cannot enter the wheel, reduced risk of large clay ball formation. This Wheel Bucket Dredger can keep high mixture density , high production and low spillage.
Various application scenarios
Bucket-wheel dredgers of various inches can be used for different soil types, from peat and clay to sand and soft rock. The buckets can be fitted with either smooth cutting edges or replaceable teeth of the pick point, chisel point or flared point variety. These replaceable teeth are the same as those used on cutter heads. Standard dredging wheels are available in a power range from 20 to 1,000kW and outputs of up to 10,000 tonnes/h.
Designed for purpose
Depending on the power required, the drive mechanism can consist of one single hydraulic motor mounted in a steel housing or can be a gearbox with several hydraulic drives. For special purposes electric drives may also be used. The gearbox and the bearings are designed for an optimal lifetime. The special sealing arrangement protects the power train from wear and damage caused by the ingress of soil. Dredging wheels are supplied as complete units, including drive and ladder adapter. They can be used on standard and customized wheel dredgers, or as replacements for cutter or wheel installations on existing dredgers.
High-quality services
We provide professional after-sales service, including video technical support, free spare parts, online support, on-site installation, commissioning and training, on-site maintenance and repair services. We guarantee that the assembly is completed and fully tested on water before delivery. Our boats can be dismantled and transported by road, rail or sea and are ready for operation upon arrival on site!
