Hydrajack Jacking Systems
Features and Benefits

Less Overall Rig Construction Cost & Considerable Less Cost vs. Rack & Pinion

60 ksi rack material used, Less Initial Construction & Replacement Cost Later

Wear on Rack is virtual non-existent, No rolling friction as with Rack & Pinion

Lock-off System is Integral part of the System, No Added Cost

Continuous Jacking Operation with Variable Speed Capabilities

Scaleable Up & Down, 100 kip – 2000 kip and Higher, Larger the Load less Cost

Less overall Wt. vs. Lift Capability & Less Overall Area in Deck Space Required

Lower Center of Gravity

Highly Reliable & Dynamic PLC Control Capability

Continuous Load Monitoring, at Lift, Parked & During Storm Conditions

Remote Diagnostics & Remote Monitoring, Easily Serviced

Retro-fit-able to preexisting Rigs of All Designs

Comparison of features of the proposed design and a conventional
Rig Jacking system

Design series - 36 pinions @ 1000 Kips per pinion 350-400 ft water depth
