Series: GC | Energy: 11,524 J (8,500 ft-lbf) | Carrier: 32–55 t (70,600–121,300 lb)
The CAT H160 GC is a hydraulic breaker built for contractors, rental fleets, demolition crews, quarry operators, and equipment owners who need a breaker that fits their carrier correctly and delivers reliable output in the field. This model sits in the GC range and is well suited for primary rock breaking, quarry operations, large-scale demolition, and high-output production applications. When a breaker is matched correctly to the carrier — by weight class, hydraulic flow, and operating pressure — operators get better production, less unnecessary vibration transmitted back to the machine, reduced wear on the attachment and bracket, and fewer problems with hoses, bushings, retainers, and seals.
The CAT H160 GC is designed for 32–55 t (70,600–121,300 lb), with a service weight of approximately 3,230 kg (7,106 lb). Oil flow requirements are 220–300 L/min (58–79 gpm), operating pressure is 13,000–16,000 kPa (1,885–2,320 psi), and the impact rate is 400–505 BPM. The energy class is 11,524 J (8,500 ft-lbf). These specifications define where this breaker fits in the lineup. A unit that is too small for the job will force the operator to work the tool harder than intended, causing overheating and premature wear. A unit that is too large for the carrier can create excess hydraulic heat, damage mounting hardware, and shorten the service life of both the hammer and the machine.
Maintenance discipline is as important as correct sizing. A hydraulic hammer operates in some of the most demanding conditions on a jobsite — dust, shock load, side load, heat, moisture, and thousands of impact cycles per hour. Even a well-built breaker will lose performance if the lower bushing wears undetected, the tool is run dry, the seals harden from heat cycling, nitrogen or accumulator pressure drifts out of specification, or hydraulic flow and pressure fall outside the recommended range. Owners should inspect the tool steel, retainers, bushings, tie rods, hoses, fittings, and the grease system on a regular schedule. A properly maintained hammer hits harder, runs cooler, and protects the carrier better than a neglected one. For many contractors, the real value of this model is not the purchase price alone — it is the ability to keep it running through repairable wear rather than replacing the whole breaker.
The design characteristics of the CAT H160 GC include Cat GC series construction, Cat-standard serviceability, carrier protection circuitry, and a high-flow hydraulic profile matched to large Cat excavator platforms. These attributes make it well suited for applications where Cat-compatible performance, field serviceability, and cost-efficient parts availability are priorities on production-class equipment. When comparing this model against similar breakers, pay close attention to carrier size match, hydraulic circuit setup, tool steel availability, and the parts support network available in your area. Matching the hammer correctly to the carrier improves efficiency and helps prevent common issues such as weak hitting, slow cycling, tool overheating, premature bushing wear, and cracked mounting hardware.
HBS provides complete support for the CAT H160 GC, including hydraulic hammer repairs, full rebuilds, routine maintenance, and sales. Parts stocked and available for this model include chisels, tie rods, upper and lower bushings, retainer pins, accumulator diaphragms or membranes, hydraulic seals and seal kits, front head components, and hoses and fittings. Whether this breaker is leaking oil, hitting weak, cycling slowly, overheating, wearing tools too fast, breaking retainers, or due for a full overhaul, HBS can diagnose the issue and return it to working condition. Contact HBS for service pricing, parts availability, rebuild options, and expert guidance on matching this hammer to the right carrier and application.
Key Features
- Impact energy of 11,524 J (8,500 ft-lbf) at 400–505 BPM positions the CAT H160 GC for high-output quarry, demolition, and rock-breaking applications on large excavator platforms where sustained energy delivery and Cat hydraulic compatibility determine production efficiency across full working shifts
- Cat GC series design provides Cat-spec internal components and hydraulic circuit integration, making the H160 GC a well-supported choice for fleet operators that need Cat-level parts availability and serviceability without the additional cost of the Performance or E Series feature package
- High-flow hydraulic requirement of 220–300 L/min (58–79 gpm) at 13,000–16,000 kPa (1,885–2,320 psi) aligns with Cat 349-through-352 excavator auxiliary circuit capacities, eliminating the circuit-mismatch conditions that cause premature seal failures, overheating, and reduced blow rate on improperly paired installations
- HBS stocks parts for the CAT H160 GC including chisels, tie rods, upper and lower bushings, retainer pins, accumulator components, hydraulic seal kits, front head parts, and hoses — supporting repairs, rebuilds, and preventive maintenance without extended wait times
