Hydraulic Jacks

Mekaster range of high performance maintenance tools includes hydraulic jacks to complement the existing range of heavy-duty sockets/wrenches, torquing tools (manual/hydraulic/electric and pneumatic), etc. More than 50 standard single acting models of hydraulic jacks are available from 5 to 200 tonnes capacity in types such as plain, screwed, hollow, short height and flat. Jacks up to 1500 T capacity can also be supplied in single/double acting models for various applications such as pile testing, post tensioning, bridge lifting and/or shifting, etc. These jacks conform to ASME B30.1 standards and are designed with a safety factor of 2:1 with components manufactured from graded alloy steel, hardened, tempered for toughness. Cylinder bores/piston rams are hard chrome plated and then honed/ground to enhance wear resistance. Pressure activated, anti-extrusion polyurethane seals of imported makes provide high reliability. Bronze guide rings provided to reduce scoring caused by off-centre loads. Replaceable hardened grooved saddles provided on ram to prevent its mushrooming. Matching hydraulic hand pumps with coupler and hoses of European origin are also available for single and multi-jack applications. These heavy-duty pumps (single/double speed) are with hardened and ground piston, integral reservoir with telescopic handle, automatic safety relief valve, modular valves for ease in maintenance etc. Electric/diesel or petrol driven pumps can also be supplied against orders.
