PRODUCT DESCRIPTION
>> Characteristics
JMZ1045 Disassemble multi-function drilling rig for limited access place is elaborately designed for grouting. anchor, micro-pile as well as core drilling at lowhead room working sites such as basements, garages, bomb shelters, culverts, small tunnels, etc. With its high rotating speed rotary head (top hammer optional) and separated drill rig and power pack, lt is flexible and more convenient in usage.
Ultra-low height: The minimum working height is only 2.5 meters, suitable for narrow Spaces such as underground garages and pipe galleries
Dual-speed power head: Freely switch between 0-44rpm (high torque) and 0-410rpm (high rotational speed)
Modular design: The main unit and the pumping station are separated, flexibly adapting to various restricted sites
Multi-functional expansion: An optional impact hammer can be installed to achieve various processes such as grouting, anchor bolt, and core sampling
