SINOVO
1 / 1
Compact size and light weight of mechanical transmission, major diameter of vertical shaft, long distance of support span and good rigidity, hexagonal Kelly ensure the torque transfer.
High speed and suitable range of speed to meet varies need of small diameter diamond bit drilling, big carbide bit drilling and all kinds of the engineering holes.
Hydraulic systems can adjust the feeding pressure and the speed, so it can satisfy the drilling in various stratums.
Pressure gauging can make you get the information about the feeding pressure at the end of the hole.
Transmission and clutch of automobile are choice in order to achieve the good generalization, easy repairing and maintenance.
Close levers, convenient operation.
Motor start by electricity, reduce labor force.
Six speeds gearbox, wide speeds range.
The spindle has the octagon section so give more torque.

The maximum drilling depth depends on the rod diameter. It can reach up to 280 meters with Ф59mm rods, 200 meters with Ф75mm rods, and down to 30 meters with larger Ф350mm configurations.
The advanced hydraulic system allows operators to adjust both the feeding pressure and speed seamlessly. This flexibility ensures stable and efficient drilling performance across various geological stratums.
The octagon spindle design provides a larger contact surface and superior structural strength compared to standard round shafts, ensuring higher torque transmission efficiency during demanding drilling operations.
Yes, this rig is designed using standard automobile transmission and clutch assemblies. This ensures high generalization, making replacement parts easy to source and maintenance operations quick and convenient.
The rig features an electric start motor system. This greatly reduces manual labor and provides quick, reliable start-ups even in harsh working environments.
The overall dimensions are 2000 * 980 * 1500mm, presenting a compact footprint for easy transportation. The total weight without the motor is approximately 1000kg.
