Power Units and Carts

PU35/PU46 Power Units are designed for high volume, high speed, pre-stressing operations. The unit can be setup for 1⁄2-inch (35 kips) or .6-inch (46 kips) stressing capability. A 10 HP – 3 PH electric motor powers an energy saving variable displacement, pressure compensated, pump that reduces heat build-up. The fully programable digital monitor allows easy tracking of initial and final pressures. Units have standard safety devices as well as fork tubes and integral lifting lugs for transport. The pull rate up to 7 seconds per foot, makes it one of the fastest machines on the market.

Availalble Options Include:

  • System transport cart with foam filled tires
  • Multiple voltage inputs 3 PH – 60 Hertz
  • 380 VAC- 50 Hertz input
  • Extended length hoses

Positioning Frames

The Positioning Frame with a chain hoist and trolley makes it simple to position the jack for stressing at the end of the bed. Twelve inch dual wheels with pneumatic casters and front swivel wheels for easy maneuverability. Standard frame is nominal 9-foot wide by 8-foot high.

Availalble Options Include:

  • Extended beam length
  • Electric or pneumatic hoist

Pull-Type Jacks

Hamilton Form’s Pull-type Tensioning Jacks are commonly used for single stroke tensioning on long-line forms where handling equipment is available and there is ample room at the end of the bed.

Tensioning jacks are available in 36″, 48″ and 60″ strokes for 1/2″ or .6 strand. A “Y”-chain sling is included for easy manipulation into strand, a magnetic torpedo level is included to make sure the unit is level and an anti-twist bar on the pulling yoke can be used to measure elongation.
