Stressing

Automatic Single Wire Stressing Jack:
The automatic universal- single-wire-stressing jack is designed for the pre stressing and post-tensioning of solid steel and strand-wire. It consists of a motor unit and a stressing jack. Different types of stressing jacks for the corresponding wire diameters can be connected to the motor unit. With a Special adapter, two stressing jacks can be connected at the same time.

We offer reliable quality and modern technology :

• Safe and easy operation due to automatic working sequence.
• Reliable due to maintenance free hydraulic in modern block construction in accordance with the CETOP-Norm.
• High working safety due to automatic depressing of the anchor grips.
• Easy handling for flexible use at construction or at the plant.
• High precision due to low friction of the sealing elements.
• The high pump and motor performance guarantee rational and fast work.

Detensioning Equipment:

After the concrete has achieved 80% of it’s specified final strength, then the stretching force can be transferred onto the elements. For this, the lifting jack and the motor driven pump unit is used to lift the stress bend, the support shells are removed, and thereafter strain is taken off the lifting jacks until the stretching force is totally transferred onto the concrete elements.
