Product Specification

>> Products Description

JC710 offers a balanced combination of compact design, efficient power transmission, and stable holeforming performance. It is particularly suited for applications such as slope anchoring, geothermal wells, and urban foundation projects where space is limited  and flexibility is essential. JC710 supports drilling depths up to 30m with a hole diameter range of φ90-152mm, ideal for shallow hardrock penetration. The system employs a φ64 mm × 3000mm drill rod and accommodates both 3" and 4" DTH hammers, enabling flexible configuration for different geological conditions.The rotation system delivers a maximum torque of 2400N·m and adjustable speeds up to 150rpm, ensuring stable rotation across various strata. The feed mechanism is powered by a robust hydraulic oil cylinder, with a 3340mm stroke and 900mm extension, producingup to 15kN of feed force and 25kN of lifting capacityallowing the rig to maintain control in fractured rock and gravel formations.
Hole range: 90-115mm
Hole depth: 30m
78kW YUCHAI engine
Equipped with a Yuchai YCD4T22T-105A diesel engine rated at 78kW, JC710 ensures reliable output while maintaining fuel efficiency with its 70L tank. The rig operates effectively with air compressors delivering 9-15m³/min at 0.8-1.6MPa, making it compatible with  common low-to-medium pressure air systems.With a total weight of only 4.6tons and a transport dimension of 5550×2050×2600mm, JC710 offers excellent transportability. Its 35° climbing capacity and 450mm ground clearance provide superior off-road performance, especially on rugged or sloped job sites. Optional winch integration and intuitive control layout enhance its operational flexibility.

>> Application

Slope Anchoring & Retaining Walls:
The crawler chassis, 35° gradeability, and 450 mm ground clearance make JC710 a strong performer on steep or uneven surfaces.

Urban Foundation & Micropile Work:
Its compact size (only 4.6 t) and 78 kW engine provide efficient hole-forming in tight construction sites, underground garages, or building retrofit projects.

Shallow Geothermal & Residential Wells:
The rig's ability to handle both 3" and 4" hammers and air compressors from 9–15 m³/min makes it suitable for low-noise, low-emission heat pump drilling in populated areas.
