Positive hydraulic seating of wedges
Strands are individually guided through jack
Anti-corrosive coating for operation in all environments
Equipped with pilot operated check valves to ensurepositive load holding
Loads can be locked or secured at any stage
TT-Series Strand Jacking System
Pre-stress Cap
Included with all strand
jacks. Used for tensioning
strand prior to operation.
From the Leaderin Heavy Lifting
Technology
Strand Wedges
Specially designed wedges foruse with Enerpac strand jacks
are included and available to
purchase separately.
Lifting bridge deck sections 100 feet was problematic and time
consuming using traditional lifting methods. Eighty-five ton
strand jacks were used to lift efficiently and safely.
LIfting in Unusual Situations
When loads need to be lifted
or lowered in tight areas or in
situations where overhead clearance is
limited, Enerpac offers this economical
alternative to traditional rigging equipment.
Lifting Attachments
A variety of lifting attachments
are available for connecting
strand to the load.
