Power Wedge™ Mechanical Pre-Stressing Device for Roof Support
The Power Wedge Mechanical Pre-Stressing Device applies active roof loads
from prop-type supports. Power Wedge converts torque into upward roof force
generating pre-stressing loads up to 10 tons. Torque is applied with a
1 1/8" (29 mm) socket via hand wrench, air or hydraulic tool. The
unit enables pre-stressing without the need for water, grout or pumps.
Creates Yieldability for Prop Supports
Operation of Power Wedge creates yieldability within the unit, making it useable with yielding or non-yielding props. The unit is designed for use with 8 1/2" (215 mm) and 10" (250 mm) diameter props. Power Wedge can also be used in place of temporary steel supports in headgates, beltways, tailgates and intersections.
