Product Overview
Model: YTR-Cat | Category: Foundation Construction Equipment
The Rotary Blasthole Drilling Rig (Cat Chassis) is purpose-built for open-pit mining and quarry blasthole drilling operations. Mounted on a heavy-duty truck chassis (Caterpillar or Doosan option), this hydraulic drilling rig delivers rapid hole penetration with precise depth control, making it ideal for large-scale mining projects requiring consistent borehole quality across granite, limestone, and overburden layers.

Mobility
1. Road-Mobile CAT Chassis
Mounted on a Caterpillar heavy-duty truck chassis, this blasthole rig trams between benches on its own wheels under road speed, so it relocates between mining faces without a low-loader. The CAT driveline is the familiar, serviceable platform found on mine sites worldwide, where parts and technicians are already on hand.
2. High-Torque Rotary Head
The variable-speed hydraulic rotary head holds steady torque through granite, limestone and overburden, adjusting RPM as formation hardness changes. Crowd feed and mast control are load-sensing, keeping bit pressure consistent for straight, quality blastholes.
3. Built for Open-Pit Production
The mast, feed and rotary group are sized for continuous blasthole production rather than occasional foundation work. Dust control, rod handling and cab ergonomics are specified for a full drilling shift on a busy bench.
4. Global Serviceability
A CAT chassis means the mine‘s existing maintenance team can support the powertrain, while Yutong supports the drilling group. Access to filters, grease points and hydraulic service points keeps planned downtime short.
Technical Parameters
About the Rotary Blasthole Drilling Rig (Cat Chassis)
This CAT-chassis blasthole drill is aimed at open-pit mines and large quarries where the rig must move quickly between working benches. Its road mobility suits operations with paved haul roads and multiple drill patterns, removing the wait for transport between holes.
Typical work includes drilling blast patterns in granite, limestone and iron-ore overburden, where consistent hole diameter and depth directly control fragmentation and downstream crusher cost. The rig handles the layered ground conditions of a mixed open-pit sequence from soil cover to weathered rock.
For mining companies across Africa, Australia and Southeast Asia, the CAT chassis choice reduces support risk: the machine runs on a platform already stocked at the mine, while Yutong engineers configure the mast and rotary group to the required hole diameter and depth. Contact the export team to size the pattern, bench height and hole depth for your project.
Yutong exports this chassis option to mines that already run CAT service teams, so the customer can staff maintenance with familiar technicians. The drilling group is supported directly from the factory, with parts dispatched from regional warehouses.

View DetailsWhy choose the CAT chassis over a crawler rig?
A wheeled CAT chassis trams between benches under its own road speed and is easier to support on mines that already run CAT service teams. For sites with multiple scattered drill patterns it removes the transport waiting a crawler rig incurs.
What rock types is this rig used on?
It is configured for blasthole drilling in granite, limestone, iron-ore overburden and weathered rock; the appropriate bit and rotary RPM are matched to the formation during configuration.
Can it drill the whole bench height?
Mast length and rod count are specified against your required hole depth and bench height; tell us the pattern and the engineering team will size the feed accordingly.
Is dust control included?
A dust collection and evacuation package is fitted as standard for bench drilling; water-assisted suppression can be added for particularly dusty formations.
Who services the chassis?
The CAT driveline is supported through the mine‘s existing CAT network; Yutong supports the mast, rotary head and hydraulics, so both sides of the machine have a clear service path.
How does it compare with the Doosan-chassis option?
The CAT chassis is the heavier, globally supported mining platform; the Doosan chassis option is a lighter, more agile alternative for smaller quarries. We will recommend the chassis to match your site size and service network.
