Overview
Hydraulic breakers (hydraulic hammers) are heavy-duty attachments used for demolition, trenching, and rock breaking. Mounted on excavators, backhoes, or crawler loaders, they convert hydraulic pressure into powerful, repeated blows to fracture concrete, rock, asphalt, and frozen ground. Breakers differ by impact energy, blow frequency, and tool size. Match the breaker’s flow and pressure specs, carrier weight class, and mounting bracket to your machine for safe, efficient operation.
FAQ
How do I choose the right breaker for my crawler loader?
Match the breaker to your carrier’s weight class, hydraulic flow (l/min) and pressure (bar/psi), and required impact energy and tool size. Check the manufacturer’s recommended carrier range and mounting bracket type.
What should I inspect when buying a used breaker?
Check for oil leaks, cracked housing, worn bushings and tool, loose or missing bolts, condition of hoses and coupler, and test operation if possible to verify blow frequency and power.
What mounting and coupling issues should I consider?
Confirm pin diameter, pin spacing, and whether you need a custom bracket or quick coupler adapter. Ensure the carrier’s boom geometry and hydraulic lines fit the breaker.
How should a breaker be prepared for shipping?
Secure the tool in a crate or on a skid, cap or remove hydraulic lines and fluid as required by carrier, secure the chisel, and protect the housing and hoses to prevent damage in transit.
Do hydraulic breakers require special handling for export or heavy transport?
Yes. Note weight and dimensions for permits, follow hazardous materials rules for hydraulic fluids if applicable, and prepare documentation for customs and insurance.
What routine maintenance keeps a breaker reliable?
Daily greasing, checking and replacing tool bushings and seals as needed, monitoring hydraulic oil cleanliness, inspecting hoses and connections, and following manufacturer intervals for seal kits and nitrogen/gas checks.
