Stressing Equipment

Center-Hole Tensioning Jacks are designed to be used on shorter forms where space may be limited. These simple, durable, easy-to-use jacks have been used extensively throughout the precast prestressed industry for over 50 years.

The Positioning Frame with a chain hoist and trolley makes it simple to position the jack for stressing at the end of the bed.

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

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.
