Large Pattern Coverage

Fewer Set-ups

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.

Features

• 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

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.

Features

• 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

• Planetary gearbox feed drive speed 27.7 m/min (91 ft/min)
• Feed mounted control panel

Rock Drill

Reliable. Durable. Low Operating Cost.

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
