Atlas Copco’s RTEX pneumatic breaker requires just 37 cfm to operate. It features the breaking capacity of a 66-pound breaker despite weighing only 55 pounds. A Sofstart two-step trigger lets the operator start the breaker slowly for full control over the chisel’s starting position and placement. A constant pressure control delivers improved energy transfer from the breaker to the RHEX power chisel, which features a concave tip profile designed to significantly reduce jamming. The RTEX features a long piston design that delivers double the surface interaction time — 100 milliseconds — of a tool with conventional pistons.
Chicago Pneumatic Construction Equipment’s RX4 breaker is designed for light demolition, landscaping, building renovation and road construction. All Chicago Pneumatic breakers feature a two-in-one design, as the cylinder and tool holder are one piece, eliminating strain and risk of seizures. A one-piece floating wear bush is designed for maximum uptime and fast, easy field replacement, while a central lubrication point is designed for quick and easy lubrication. Featuring a service weight of 470 pounds and an impact rate of up to 1,300 blows per minute, the RX4 is specified for carriers with a capacity of 6,400 pounds to 13,200 pounds.
Doosan hydraulic breakers are available in impact energy classes — from 2,000 to 8,000 foot-pounds — and are designed for use with seven Doosan crawler excavators (DX140LC-5 through the DX350LC-5) and the DX140W-5 wheel excavator. The DX140W-5 wheel excavator is designed for quick and easy transport. All Doosan hydraulic breakers feature an energy recovery system designed to increase strike power. The nitrogen-powered Doosan hydraulic breakers are equipped with an upper/lower suspension system that isolates the power unit from the housing, making them a fit for a variety of demanding applications.
The Hilti TE 800-AVR breaker features Hi Drive technology designed to help deliver 15 foot-pounds of impact energy. The breaker’s D-handle design offers versatility for optimal horizontal and vertical breaking. Used in concert with Hilti’s TE-SW wall chisel, the unit delivers optimal impact energy and control for wall demolition. The TE 800-AVR’s triple chamber sealing design isolates the hammering mechanism, the piston area and chuck helping prevent dust and other harmful external elements from entering the gearing. Meanwhile, the breaker’s active cooling system provides active airflow over electronics, motor, gear and hammering mechanism towards the tool chuck to keep operating temperatures low.
John Deere’s Hydraulic Hammer attachments (HH20C, HH40C, HH60C and HH80C) for skid steer loaders, compact track loaders and compact excavators are optimized to work with select John Deere G- and E-Series skid steers and compact track loaders, G-Series compact excavators and most competitive models. The Hydraulic Hammers are designed to provide two to three times more blows per minute than previous models. With 30 percent fewer parts, rebuild times are reduced to one hour versus eight hours, and an exclusive tool retention system enables quick installation and removal using only one small screwdriver. The units only require grease after every two hours of operation and have a 1,000-hour service interval.
