550T HDD machine KDP-550
It is mainly used for the civic engineering (pipe laying), with 5500KN pull capacity.
Features and Benefits
KDP-550 rig is split in structure, with the main power station, the mainframe and the control cabin being all independent, offering flexibility and ease of mobility on site. The rig's main power station can be installed with crawler track in accordance with the customer's requirement. The mainframe is installed with diesel engine (145kw) to make it move. Power and hydraulic system are featured by:
(1) The main hydraulic components are all well-known products at home and abroad. Equipped with two engines, which can work independently or jointly, the rig is strong in power. In case that one of the engines fails to work, another one can still work, greatly improving the safety of operation.
(2) The hydraulic valve group of the rig can be controlled electrically and manually. In case there is failure occurring in the electrical circuit, the operation can be controlled manually.
The clamp shackle device is featured by:
(1) The reliability of drill rod's shackle is greatly improved by using the three-jaw closing structure
(2) With clamping force being adjustable, the operator can adjust the clamping force in accordance with size of rods and the project's requirements so as to lengthen the lifespan of rods and clamp teeth.
(3) The clamp shackle is compact in structure. It can work properly even when the connector of rods is very short in length.
(4) The clamp shackle can move within the range of full stroke so as to guarantee the break-out of rod connector at any position.
Power head is featured by:
(1) Instead of slide friction, the move of the rid is made by roller rack friction so as to reduce the power loss.
(2) The floating structure is used for the main shaft so as to avoid the wearing in the process of demounting the shackle of the rod.
