Audited Supplier
Our subsidiary company, Bonny tracked undercarriage factory, is specialized in the research and development of rubber and steel crawler undercarriage. Since the establishment of Bonny, it keeps the whole world in view and blaze steadily new trails. By now, we have developed various tracked undercarriage systems and the load capacity is from 0.5 ton to 20 ton. It has been widely applied in drilling machines (core drill, horizontal directional drilling rig, belt engineering drill, and engineering rig), engineering machines, mining, colliery, agricultural and gardening machines. Meanwhile, we have a lot of experience engineers who can provide you technical support and technical consultancy to meet your needs.
Picture of undercarriage for reference
- Adopt steel tracks or .steel tracks and block rubber.
- The track motor can be fixed displacement or variable displacement concealed planetary gearbox and hydraulic motor, such as Nabtesco (Japen), Brevini (Italia). If you need, we can also provide track motor made by our own factory.
- The beam is made of Q345B with high loading capacity.
- It can also be designed and manufactured on customers' request.
- It is widely applied in all kinds of large drilling rig, excavator, paver, Aerial Working Platform and construction engineering machines.
