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 shank so the wave form is properly matched for maximum energy transfer to the bit.
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 large accumulators provide a smooth and efficient hydraulic oscillation
Owner Serviceable
Cat Rock Drills are so simple that owner serviceability is a viable alternative and cost savings.
Other models require servicing in a clean room environment
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
New Automated Rock Drill Lube System
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.
Components reach full life expectancy at proper lube intervals
Grease reservoir capacity can hold enough for up to five 10 hour shifts
A timer board cycles the grease pump throughout the day eliminating maintenance time
High and low pressure conditions are continually monitored through the display screen
Providing you with proven versatility, the MD5125 is equipped with a sturdy rod changer that holds multiple rods allowing the boom extension to reach far and drill deep while maintaining stability. Each feed and rod changer can accommodate various lengths and diameters of drill steel. The selection and use of drill steel varies based on the desired hole depth and diameter per the blasting plan.
A sturdy boom and feed support the carousel rod changer providing excellent pattern coverage and fewer required setups. The heavy-duty boom is constructed of thick square tubing with steel plate reinforcements in key areas to add strength. Built with high strength steel channels with diagonal internal bracing, the feed system resists torsion and thrust loads.
