Yuchai Powered Telescoping Mast Well Drilling Rig 500m 26T Pullback Capacity JKS500S

The JKS500S Yuchai powered telescoping mast well drilling rig pairs a dependable 132kW Yuchai engine with a 500m drilling envelope and 26T pullback capacity. The telescoping mast and 6700mm feed stroke make this one of the fastest-cycling rigs in its class, while the 12.5T machine weight keeps ground pressure low enough for soft quarry floors and mine benches. Operators appreciate the dual rotation range of 0-35/70rpm, which provides fine speed control for reaming and casing work. Hydraulic supporting legs with 1650mm stroke level the machine quickly, and an optional 1500L/min centrifugal mud pump or 500L/min plunger pump expands the rig into mud rotary and dual-mode drilling.

• Yuchai 132kW engine: proven, fuel-efficient power plant with strong service networks across Africa, Asia and Latin America.
• 26T pullback capacity: extra pulling power for deep strings, casing extraction and stuck tool recovery.
• Long 6700mm feed stroke: fewer rod connections, faster drilling cycles and reduced thread wear.
• Telescoping mast: retracts for transport and extends on site; 1650mm hydraulic leg stroke levels steep terrain.
• Dual rotation range: 0-35/70rpm gives the operator precise speed control for different bit types and formations.
• Mud pump options: centrifugal 1500L/min or plunger 500L/min pumps enable mud rotary and combination drilling.

The JKS500S is a versatile performer for quarry water supply, mine camp boreholes, rural water projects and geothermal loops. The long feed stroke and strong pullback make it particularly effective in deep unconsolidated formations where casing must be driven and extracted frequently, and the optional mud pumps extend its reach into clay, sand and gravel sequences.

Every JKS500S is packed in export seaworthy style with steel frame support and protective wrapping, after passing full load tests on the feed system, winches and hydraulic legs. Delivery includes a one-year warranty, operator and maintenance manuals, a starter spare parts kit and online remote support for commissioning and operator training.
