Production Description

The HydraPRESS is a state of the art truss assembly machine that combines the rapid pressing cycle of multi head presses, with the speed and ease of computer driven setup.

The HydraPRESS has been developed for short or long production runs and is capable of efficiently manufacturing many of the more complex truss shapes for which conventional multi-head presses have not been considered suitable. As the press head positioning, timber stop, camber adjustment and plate location are all automatically positioned, the

HydraPRESS can be efficient with production runs of little as 1 or 2 trusses.

The production cycle time is also improved compared with other multi heads, as the HydraPRESS incorporates nail plate placement. Typically, assembly cycle time for an A Type truss, including placing of timber and unloading finished truss, is 50 seconds and set up time 15 to 30 seconds. The flow of material to the press and the removal of finished trusses will determine the overall productivity of the machine.
