Square Spiral Machines

The Square Spiral Forming Machine forms 6″ to 30″ continuous square spirals from wire up to 3/8″ diameter. The machine is powered by a 10 hp electric motor coupled to a variable displacement hydraulic pump. The pump displacement is variable for precise speed control without buildup of heat. The forming head jog and reverse functions are incorporated into push button controls. The forming head speed is continuously variable from 10 to 45 rpm. The predetermining electronic counter can be preset for a given number of turns per coil. The forming machine stops automatically after the preset number of turns is formed to eliminate manually counting back each time a coil is cut off. The counter keeps track of the batch count as well. The forming head stops automatically when the guard is raised. The different sized heads can be accommodated by moving the follower head carriage assembly toward or away from the forming head. The forming heads are mounted with split taper bushings for easy changeout.

Setup time is minimal due to quick release cam levers incorporated into the adjustments throughout the machine. An external air supply capable of 120 psi at very low volume is required to charge the air cylinder which acts as a spring on the follower head carriage.

Architectural Casting Table

Hamilton Form’s Architectural Casting Table is designed to produce prestressed panels with an architectural finish. The understructure is made up of paired channels with stressing bars running through the channels. Load is transferred through the bars to the jacking abutments. The table is topped with a wood deck finished by the precaster to create the desired architectural finish. This design leaves the casting surface totally unaffected by stress loads.

Optional Features Include:

  • Fixed steel side rails
  • Hydraulically operated side rails
  • Adjustable jacking plates and hanging weldments
  • Spandrel loading capacity on one or both sides of the table
  • Vibrotrack™ vibration system attached to the underside of the table
  • Capstan winch system for Vibrotrack™

Supporting Equipment Available:

  • Flat Deck Cleaner
  • Stressing Jacks
  • Power Units and Carts
  • Strand Needles
