Overview
MD5075 Track Drill
The Cat® MD5075 achieves large pattern coverage with a sturdy extendable boom and reduces your cycle time with an efficient carousel rod changer. Its powerful rock drill, durable Cat components, and ease of maintenance contribute to the exceptional value of this proven machine.
Specifications
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.
Boom length 3.81 m (12.5 ft)
Boom extension adds 1.5 m (5 ft)
Boom swing capability is 45° L to 24° R
Boom angle capability is 36° lift angle to 29° below horizontal angle
Optional knuckle boom 5.9 m (19.25 ft)
Feed table is 2.7 m (9 ft) with a 0.9 m (3 ft) extension
Planetary gearbox feed drive is capable of 3347 kg (7,379 lb) feed force and 27.7 m/min (91 ft/min) speed
Lighting on the feed illuminates the carousel and hole site for around the clock drilling
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 sturdy 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 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
Standard on the MD5075 is 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.
