Description
JK820 — The Rig That Earned Its Reputation in the Field

Spec sheets are easy to write. Real-world performance is what separates a reliable drill from a headache. The JK820 has accumulated over 200 units in active field operation across quarries and construction sites in Yunnan, Guizhou, Sichuan, and Guangxi. Every improvement in the current version comes directly from operator and site manager feedback — not from a marketing department.

What We Fixed Based on Real Feedback
Dust ControlUpgraded from single to dual-layer sealed dust hood — airborne dust reduced by over 40%, keeping the worksite compliant with environmental regulations
ControlsSwitched from mechanical linkage to pilot hydraulic joysticks — smoother response, less operator strain over an 8-hour shift
UndercarriageTrack rollers increased from 5 to 7 support rollers — better load distribution on soft ground and rocky slopes
Hydraulic LinesRouting optimized during revision — hoses no longer rub against frame members, hose life extended significantly
Parts and Service — No Long Waits
📦 Wear Parts Included

Every JK820 ships with a consumables kit — seals, filters, grease fittings — enough for the first 6 months of routine operation.

🚚 48-Hour Parts Dispatch

Common spares stocked in provincial warehouses. Specialty parts shipped within 48 hours to any domestic address — export shipments via DHL/FedEx.

🔧 Mature Component Supply

Engine, hydraulic pumps, and motors are all domestic mainstream models — parts available at equipment dealers in every province, not locked into a single supplier.
