HYDRAULIC HAMMER HIRE

DOWIN T Series Hydraulic Hammers

Superior quality alloy steel provides excellent durability. See Table below for full specifications.

Hydraulic-gas power system

  • Pressurized N2 gas in main power cell is to operate with less demand on the base machine’s hydraulic power

Fewer components

  • Minimised inner parts help easy maintenance with low cost
  • DOWIN T series breakers are designed to harmonise the long piston stroke with the nitrogen cushion on the top of the piston, creating less shock and vibration than competing breakers.
  • Superior quality alloy steel provides excellent durability and longer life.
  • Box Type breaker was developed to minimize the noise during operation, with use of sound absorbing materials and noise reducing frame design, very useful in the job site of urban area.
