Cembre HT51 Hydraulic Crimping Tools - User Instructions

Cembre HT51 tool is suitable for crimping electrical cable connectors, lugs and splices for conductors up to 240sqmm (500 MCM).

  • Select the appropriate die set for the connectors (crimp lugs or splices)
  • Open the latch and release the upper die holder of the crimping tool
  • Insert one die into the upper die holder and one die into the lower die holder
  • Close the latch
  • Remove the handle holder to release the moveable handle
  • Insert the conductor into the connector (crimp lug or splice)
  • Locate the connector between the crimping dies at the desired crimp position
  • Operate the crimp tool handle for die set advancement
  • Ensure crimp dies are positioned exactly on the desired crimp point
  • Continue crimping using the moveable handle
  • Crimp tool will change to high pressure stage, ram will advance until dies meet
  • Continue pumping the crimp tool until maximum pressure valve is activated
  • Listen for "click"
  • Press pressure release lever for retraction of ram and die re-opening
  • The crimped connector will be released
  • Press the pressure release lever to release the oil pressure in the crimp tool

Crimping Tool Tips & Notes : Ensure that the latch and upper die holder of the Cembre HT51 are fully secured to avoid damage during crimping. The automatic opening of the moveable handle allows the operation of the hydraulic crimping tool using one hand, while locating the connector (cable lug or cable splice) into the required crimp position with the other hand. Cembre HT51 crimping tool has a twin speed operation and automatically switches from a rapid advancing speed of the ram to a slower more powerful crimping speed as the die sets close and compress onto the connector.

Crimping Tool Maintenance : Dust, sand and dirt threaten the safe and reliable operation of all hydraulic crimping tools - after use the Cembre HT51 should be cleaned with a clean cloth taking care to remove any residual especially close to pivots and movable parts.
