CASE STUDY BoomerHD XHD Series HEAVY DUTY ROCKBREAKER FOR UNDERGROUND MINING

Scope of Project Designed, engineered and fabricated within 30 weeks,Transmin delivered Due to ongoing maintenance ahead of time and on budget - easily problems with their existing meeting the Clients expectations and Rockbreaker, Transmin was INDONESIA requirements. approached to design, engineer and fabricate a heavy duty Rockbreaker To date Transmin has supplied that could handle very competent, the client with over 13 BoomerHD abrasive rock underground at a mine Rockbreakers which all utilise the based in Indonesia. Location: same or similar cylinders, hammers Papua, Indonesia and power packs which make for Working in a high vibration, high good commonality for spares on site. Operation Type: humidity and dust laden environment, Gold Ore & Copper the Rockbreaker’s job is to break The XHD series supplied is oversize and bridging rock in, around Equipment Solution: considered to be the heaviest and over the gyratory crusher. It duty Rockbreaker presently being BoomerHD XHD Series must be able to reach, manipulate manufactured. and break rocks, with the hammer operating in a vertical position. Project Outcome Key Features: Transmin’s standard design of cylinder rod-ends with full penetration butt  Heavy Duty Design  Radio Remote Control welding and 100% ultrasonic testing Decades of testing and analysis Allows precise movements were supplied.

The arduous conditions. system was designed to enable the tapered caps at each end of the pin to provide rigid support, even though the pins may become worn. The taper lock system also allows easier maintenance and access to the pins.

To date the boom system is working better than expected - aiding plant productivity and reducing downtime.
