CM358A Energy Saving Crawler Mounted Hydraulic DTH Drilling Rig 90-165mm Blast Hole Electric Motor Option

This CM358A crawler mounted hydraulic DTH drilling rig is designed with operating cost as a priority, offering an optional 45 kW electric motor drive that lets operators run the rig on grid power instead of diesel. For quarries and mines with on-site electricity, the electric option cuts fuel bills dramatically and reduces exhaust emissions inside pits and confined working areas, while the diesel engine remains available for remote sites and tramming. The rig drills 90-165 mm holes to 50 meters using a Yuchai 70 kW or Cummins 74 kW diesel engine, delivering 3000 Nm of rotation torque at speeds up to 80 rpm. At just 6100 kg with a 6900 x 2200 x 2200 mm footprint, the CM358A is one of the most transportable rigs in its class.

• Energy Saving Design: optional 45kW electric motor drive cuts fuel consumption and emissions significantly.
• 90-165mm Blast Hole Range: full production hole coverage for quarry and mining blasting.
• 50m Drilling Depth: multi-pass capability in a compact, lightweight package.
• Dual Power Choice: Yuchai 70kW or Cummins 74kW diesel, plus electric motor option.
• 6100kg Light Weight: low transport cost and easy movement between sites.
• Compact 2200mm Width: works in narrow benches and confined quarry areas.

The CM358A appeals to quarry operators who drill in the same location for years and can take advantage of grid power, as well as to contractors who move frequently and value the rig's light weight and low transport cost. The electric drive option makes the machine particularly attractive for operations with strict environmental regulations or for indoor and semi-enclosed excavation work where diesel fumes are a concern. Typical applications include limestone and sandstone quarry blastholes, aggregate production, building foundation excavation, and small mining operations. The dual-power flexibility also provides a useful backup: if the grid supply fails, the diesel engine keeps production moving.

Every CM358A is factory tested with both power configurations verified before shipment, and the electric motor option is installed and run-tested when specified. The rig ships in a 40ft open top container or flat rack with full protection of the mast and hydraulic components. The documentation package includes CE certification, engine and electric motor compliance papers, operation manuals, and wiring diagrams. Our support team assists with on-site commissioning and can advise on the correct electric supply configuration for your location.
