Main Technical Data of XR25 Multi-funtional Combined Rotary Drilling Rig |
|
■ Performance Characteristics(XR25)
■ The XR25 rotary drilling rig is composed of crawler chassis and the drilling device. It's a kind of machine that can be used to drill for the concreted pile in the construction engineering. It can be widely used for the in miniature project such as: the town construction, lower building and maintain the building etc.
■ The XR25 rotary drilling rig doesn't need any other power to drive the machine.
■ The XR25 model is equipped with expert chassis which has super stability. The chassis has high strength of structure . It is convenient to transport and with super travel ability.
Crawler length 2458 mm
Track shoes width 400 mm
The quantity of Long-aged supporting weight drum 2×6.
■ The main parts
The chassis of XR25 rotary drilling rig is fixed with hydraulic circuit which is composed of engine, steel pipe and high pressure joints. Also the hydraulic valves, hydraulic tank and fuel tank, the hydraulic oil filter, the air filter and the oil pump are fixed in the machine. The unique hydraulic oil cooling system is special designed for the work of field with high temperature.
■ Built-in hydraulic winches
The XR25 rotary drilling rig fixes the main and auxiliary winches on the mast and it can be operated conveniently. The main winch has the function of controllable freefall to make sure the speed of drill and the cable is the same. During the process of drilling, the main winch also has an auto-tightening function.
Main winch
single line pull 30 kN
Rope dia. 13 mm
Auxiliary winch
single line pull 10 kN
