Key Advantages
Why Choose MC2-150B Bolt Punch
Engineered for the toughest mining maintenance environments — built to outperform traditional methods and protect your critical equipment.
-
Powerful Dual Impact
- 1500J horizontal impact energy and up to 3600J vertical max impact. Supports both inching and continuous striking modes for fast seized bolt removal.
- Air Spring Recoil Buffer
Rear air spring with nitrogen charging effectively buffers and eliminates recoil force. Operators feel minimal kickback, ensuring safer and more comfortable operation.
- Imported Hydraulic Core
Korean imported cylinder valve spool and full sealing kits. Outstanding pressure resistance, wear resistance and high temperature resistance for stable hydraulic output.
- Full Electric Safety
Phase sequence protector prevents motor reverse rotation damage. Integrated high-pressure alarm, operation indicator, oil return indicator and emergency stop switch.
- Robust Manufacturing
Laser-cut structural parts, automatic welding, shot blasting derusting and assembly-line plastic spraying. Strong paint adhesion, smooth glossy surface, long-lasting without fading.
- Complete Spare Parts
Full set of spare seals, filter elements, punch tips, nitrogen charging tool and 4L nitrogen cylinder delivered together. Ready for immediate field maintenance.

Common Questions About MC2-150B
Everything you need to know about the hydraulic bolt punch for your mill maintenance operations.
1. What is the MC2-150B bolt punch used for?
The MC2-150B is a professional hydraulic impact tool specifically designed to remove rusted, corroded, and seized ball mill and SAG mill liner bolts during mill maintenance and liner replacement. It delivers 1500J horizontal impact energy to push seized bolts inward without damaging the mill shell.
2. What size bolts can the MC2-150B handle?
The MC2-150B is suitable for punch rod diameters from 30mm to 80mm, covering the vast majority of standard ball mill and SAG mill liner bolt sizes. Custom punch rod sizes and lengths (350–600mm) can be supplied based on your specific mill requirements.
3. Will this bolt punch damage the ball mill shell?
No. The MC2-150B uses controlled axial impact that directs force along the bolt axis, avoiding excessive damage to mill shell bolt holes. This is a significant improvement over gas cutting or heavy sledge hammer methods, which can crack or deform the mill shell and require costly rework.
4. Does the MC2-150B come with a hydraulic power pack?
Yes. The standard supply includes a complete 18.5kW hydraulic power unit, the bolt punch assembly, two 15-meter high-pressure hydraulic hoses, and two custom-size punch rods. The system is delivered as a turnkey package ready for immediate field operation.
5. What safety features are included?
Key safety features include: air spring with nitrogen charging to buffer and eliminate recoil force, phase sequence protector to prevent motor reverse rotation damage to the hydraulic pump, high-pressure alarm, operation indicator, oil return indicator, and an emergency stop switch. The system provides full-process multi-safety protection.
6. What is the warranty period and shipping method?
Warranty is 18 months from the shipment date OR 12 months after site acceptance, whichever comes first. The equipment is packed in a sealed plywood export wooden case, suitable for sea freight. We ship worldwide with full documentation including assembly drawings, operation manual, product certificate and packing list.
