Large Pattern Coverage
Fewer Set-ups

Large Pattern Coverage

Drill more holes with fewer set-ups thanks to a sturdy boom system that is telescopic, has a 1.52 m (5 ft) extension, and swings 40 degrees to the left and right. For even greater flexibility in drill patterns, the MD5090 feed swings 36° L to 37° R and it also extends 0.9 m (3 ft).

Cabless Design
No Cab. No Limits.

Cabless Design

  • Cost effective alternative to drills with cabs
  • Highly maneuverable
  • Lighter in weight
  • Wide boom swing
  • Large pattern coverage
  • Easy to transport

Boom and Feed
Extends Your Reach

Boom and Feed

A sturdy extendible boom and feed provides excellent pattern coverage and requires fewer setups. The heavy-duty boom is constructed of thick square tubing with steel plate reinforcements in key areas to add strength. The feed system resists torsion and thrust loads because it is built with diagonally braced high strength steel channels.

  • Boom length 3.81 m (12.5 ft)
  • Boom extension 1.5 m (5 ft)
  • Boom swing 40° L to 40° R
  • Feed swing 36° L to 37° R
  • Feed extension length 0.9 m (3 ft)
  • Feed wear pads are replaceable
  • Planetary gearbox feed drive speed 27.7 m/min (91 ft/min)
  • Feed mounted control panel

Rock Drill
Reliable. Durable. Low Operating Cost.

Rock Drill

The MD5090 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.

Reliable Performer
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
