JAH Range

The JAH range of lightweight aluminium jacks offers a wide variety of capacities and lift height options. Available as either plain ram lifting jacks, with or without “failsafe” mechanical lock ring, or optional low height claw lifting design, all models are constructed predominantly of lightweight aluminium alloy with all critical functioning parts manufactured from high quality steel. Used extensively in maintenance, construction, heavy plant and machinery applications, these high quality jacks are the proven industry standard.

  • Internal safety overload device
  • Lightweight construction
  • Available with plain piston, lifting claw or failsafe mechanical lock ring
  • Claw lift capacities from 8 to 24 tonnes
