Benefits & Features
The basic differences between the two models are their undercarriages and pattern coverage capabilities. The MD5050 has a standard undercarriage and a 0.61 m (2 ft) boom extension for a large pattern coverage. Whereas the MD5050 T undercarriage has a unique 360° turntable and a 1.2 m (4 ft) boom extension for the largest pattern coverage possible. This is achieved with its ability to turn 360° for positioning the drill in tight spaces.
You can expect a long life due to the structural integrity of our robust undercarriage designs. Despite the unyielding demands of drilling and tramming rough terrain, our structures are continually proven reliable. Extreme maneuverability is yours thanks to the low center of gravity high ground clearance on MD5050.

Hydraulic motor-driven track assemblies
Dual tram maximum speed 4.0 km/h (2.5 mph)
Gradeability 35°

MD5050
B-3 excavator
Ground clearance 380 mm (15 in)
Ground pressure 0.82 bar (12 psi)
Track gauge 198 cm (78 in)
Wide triple grousers 300 mm (11.8 in)

Cat Grease Lubricated Track (GLT)
Each track joint is sealed to retain the grease between the pin and bushing
Track noise is reduced because there is no metal to metal contact between the pin and bushing
The grease lubricant prevents frozen or seized track joints
To improve your overall productivity, our new carousel rod changer significantly reduces rod change time. Additionally the carousel is supported by a sturdy feed and the extension boom allowing for large pattern coverage so fewer set ups are required.
Our carousel rod changer is light weight and holds more rods, allowing the boom extension to reach further and drill deeper while maintaining stability. The feed and carousel rod changer can accommodate multiple lengths and diameters of drill steel.

Low cost of ownership and reliability are yours with renowned Cat Rock Drills. Building on a legacy of simplistic power, these drills have long life expectancy and are field serviceable.
This combination of robust design and easy maintenance means more hours of reliable, low-cost operation. For added efficiency, the pistons are matched to the cross section of the rod so the wave form is properly matched for maximum energy transfer.
Durable Design
A simple design coupled with high strength materials yields exceptional durability.
Having only half of the components of competitive models, there are fewer internal parts to wear
There are four major housings bolted together with high strength flanges eliminating troublesome long tie rods
Long life alloy bushings
Fast response accumulators provide a smooth and efficient hydraulic oscillation
Long leakage paths of the oscillator bearings yield high volumetric efficiency
Owner Serviceable
Cat Rock Drills are so simple that owner serviceability is a viable alternative and cost savings.
Other models require downtime for round trip transportation to a clean room environment
Only their OEM service technicians can perform the maintenance and repairs
All maintenance and rebuilds can be done in your shop and some maintenance can even be done with the rock drill still mounted to the feed
Accumulator assemblies may be replaced in the field
Troubleshooting is easy since there are half the components of other drills
Automated Rock Drill Lube System – Optional
Peak performance is sustained when your rock drill is kept lubricated, cool, and automatically maintained with our new Auto Rock Drill Lube System. Operators no longer have to stop drilling to manually grease the rock drill every two hours.
Saves more than forty hours a year over manual greasing
Components reach full life expectancy at proper lube intervals
Grease reservoir stores supply for up to five 8-10 hour shifts
A timer board cycles the grease pump throughout the day eliminating maintenance time
High and low pressure conditions are continually monitored
MD5050 is equipped with the HPR4519 hydraulic powered percussion rock drill rated at 19 kW (25 hp) output energy with dual hydraulic variable rotation motors producing 908 N∙m (670 lbf-ft) torque.
