Most common system for guidance on OUTSIDE of track. It can consist of one to four Accu-Rolls, mounted to the roller. Ideal for any system, permanent or temporary. Flat bar mounted to factory floor provides low height, accessible rolling system with minimal floor surface obstacles.
Accu-Roll Guidance
Type R - Type U
Type C
Common system for guidance INSIDE a track or a track embedded in concrete floor. It can consist of one to four Accu-Rolls; two can be installed on one end or on one side, or in center of Roller frame side. Track can be standard channel, inside flanges of H-Beam, fabricated track from back-to-back angles, etc.
Type U
Most often added to Type R system. It can consist of one or more Accu-Rolls per side. It prevents UPLIFT in dynamic conditions; resistance against wind and buoyancy; protection against overturning moment and aids in moving top-heavy or eccentrically loaded equipment.
Type TR
The Accu-Roll System is designed for applications involving turntables, revolving machinery, or equipment that moves along a fixed radius, typically consisting of three Accu-Rolls and modified roller chains to fit the required radius. Rollers of the 37.5 OT (Oversized Top) size and larger can operate on diameters as tight as 8 feet (2.5 meters)
Top Modifications
Modifications to the top plates of Hilman Rollers can range greatly. Some relatively simple top modifications might be special drilled and tapped hole patterns, connecting studs or tops machined to close tolerances. Top clamps, hinged adaptations or container fittings can be added to the rollers, as well as other types of attachments, for the purpose of mounting to a specific type of footing or pad. Rocker Tops are also available.
Chain & Frame Modifications
There are several different modifications that Hilman can do to the chains. Tapered roller chains allow Hilman Rollers to follow a fixed radius. Keyway chains are an internal guidance feature to maximize chain life. In highly repetitive applications or where rollers encounter bursts of speed; the Keyway feature keeps the chain centered in the roller frame. Concave and Convex chain and frame solutions are also possible. Hilman can even design specially contoured chain where the rolls are machined to match the contour of crowned rails, ensuring sufficient contact area.
Track Wipers or Dirt Shields
Many wiper and shield styles can be added to Rollers for use in extremely dirty or abusive conditions to minimize the exposure of dirt and dust to the roller chain.
