THUNDERBOLT 1500 Special Performance Recoilless Hammer

RME’s Liner Bolt Removal Tool (LRT), the THUNDERBOLT 1500 Special Performance Recoilless Hammer, replaces heavy manual sledge hammers, hydraulic rock breakers, jack hammers and heavy battering rams by delivering a high momentum 1500 joule blow once every second.

This liner bolt removal hammer is suitable for larger mills and with heavier liners and larger liner bolts, where sledge hammers are of no use and battering rams a very unsafe alternative.

THUNDERBOLT 1500s are hydraulic, deliver ten (10) times the hitting power of a typical man and strike sixty (60) times per minute, continuously. The THUNDERBOLT 1500 will remove bolts and liners that are impossible to move by sledge hammering or pneumatic breakers and which otherwise require the use of unsafe battering ram techniques.

THUNDERBOLT 1500s each require a THUNDERBOLT Power Pack to supply the hammer’s electrical requirements and hydraulic requirements for hammer and powered suspension options. THUNDERBOLTs can be specified to accept any standard 3 phase supply (380, 415, 480, 525, 575, 600 Volts at 50 or 60 Hz).

Each THUNDERBOLT 1500 weighs 449kg (988lbs). Requisites for operating the THUNDERBOLT 1500 include:

  • Power Pack
  • Connecting hose and cable set
  • Standard Moil
  • Manuals
  • Nitrogen gas accumulator charging kit
  • Service kits


THUNDERBOLT 1500s can be supported by overhead crane (only recommended for initial trial, since the crane is a scarce resource in a shut down situation), THUNDERBOLT Twin Tube Monorail or Telescoping Jib. For information regarding Hammer suspension options, please refer to Hammer Suspension.
