When it comes to demolition, quarrying, or trenching, you don’t just need raw force—you need a reliable partner that matches your machinery seamlessly.
Rockwell Enterprises (Indore) brings you the heavy-duty MJack Series Hydraulic Rock Breakers (MJ 40, MJ 43, MJ 50, and MJ 81). Built to tackle India’s most unforgiving geographic terrains, these high-impact breakers turn your existing fleet into high-yield excavation assets.
Whether operating a backhoe loader, a heavy crawler excavator, or a customized tractor attachment, the MJack series delivers industry-leading power-to-weight ratios with minimal maintenance overhead.
Why the MJack Series is the Preferred Choice Across India
1. Universal Attachment Adaptability
A true fleet multiplier, the MJack series is engineered with versatile flow-valves. It easily mounts onto:
- Backhoe Loaders: The standard for Indian infrastructure.
- Excavators: For deep cuts and massive volumes.
- Tractor Attachments: A highly economical alternative for rural development, leveling, and local contracting.
2. Advanced Vibration & Housing Technology
The MJack series utilizes high-strength urethane cushion pads inside a full-box silenced housing. This dampens shock waves, protecting your carrier vehicle's arm and pins from premature structural wear while dramatically reducing site noise levels.
3. Pan-India Supply & On-Site Support
Based out of the centrally located hub of Indore, Madhya Pradesh, Rockwell Enterprises guarantees fast transit times and continuous spare-parts availability (chisels, pistons, pipeline kits, and seal kits) to every corner of India.
Frequently Asked Questions (FAQs)
Q1: Can I run the MJack MJ 40 or MJ 43 on a standard agricultural tractor?
Answer: Yes! With a rear-mounted hydraulic attachment framework and matching PTO-driven or independent auxiliary pumps, the MJ 40 and MJ 43 models perform exceptionally well on tractors. This makes them highly popular for rural rock-breaking and farm preparation.
Q2: What is included in the installation support from Rockwell Enterprises?
Answer: We supply complete, high-grade pipeline kits tailored to your specific carrier machine (e.g., JCB 3DX, Komatsu PC210). Our network provides guidance for correct pressure adjustments (ranging between 160 to 180 bar depending on the model) to ensure peak impact rate and zero hydraulic back-pressure.
Q3: How do I choose between the MJ 50 and the MJ 81?
Answer: It boils down to your carrier size and material hardness. If you operate a standard backhoe or a 10-ton machine for urban projects, the MJ 50 is ideal. If you are doing primary breaking in heavy mining or handling a 20-ton crawler excavator, the massive 140mm tool diameter of the MJ 81 is required.
Q4: How can I order from outside Madhya Pradesh, and how are spares managed?
Answer: Rockwell Enterprises offers Pan-India supply with seamless transport logistics. We maintain an extensive ready stock of replacement Moil/Wedge chisels, premium PU pads, and nitrogen gas charging kits at our Indore warehouse to minimize your project downtime.
