The combination of a low friction and accurately guided roller can be very useful, especially if the distance is great and the final placement needs to be precise. Additionally, if the item being moved requires careful handling, the more accurate a move generally the better.
An Accu-Roll Guidance System is an addition to a Hilman Roller that is designed to better integrate the roller with some type of uniform track, for the purpose of maintaining positive alignment during a move. Accu-Roll Systems can be designed for virtually any roller but mostly it is the XYS, ERF, OT/NT/T and SHD Series Rollers that benefit most.
In general the OT/NT/T-Series and the SHD-Series are the most common to utilize Accu-Roll systems. As standard designs they offer the most versatile platforms to start from in terms of the range of capacities and variety of top styles.
Hilman Rollers with Accu-Roll work best on steel flat bars and structural shapes; such as inverted channels, I-beams and Wide-flanged beams. When selecting a track it is important to make certain that the width and thickness properly accommodate the width of a roller’s footprint where it is intended to be in contact on the track. It is also important to consider the sub-surface of the track to make sure it is supported properly.

Hilman Rollers can be used in corrosive environments with a high degree of confidence so long as they are manufactured with the proper materials. Stainless Steels and epoxy coatings can prolong the life of Hilman Rollers when used in offshore applications or in environments that are otherwise corrosive.
ABS, DNV and Lloyd’s certifications are just a few that Hilman has procured to be certified for offshore use.
Occasional applications may benefit from the integration of hydraulic cylinders, either as motive force or to lift a load for a specific reason; or both. Hilman has supplied several different combinations of hydraulically integrated skidding systems for use on land and at sea. Hilman can provide complete controls for a turnkey solution.
Keyway Rollers are a unique way of providing a guidance system to a Hilman Rollers. Whereas an Accu-Roll Guidance System is external of the standard size roller frame, a Keyway Roller has what we call an internal Guidance System.
Keyway Chains have a groove machined into the rolls that mates with a track that is machined into the roller frame’s load plate.
Hilman Rocker Tops are designed for integration with Hilman OT and NT Series Rollers in order to provide some degree of articulation. Rocker Tops can be made custom for a variety of other rollers as well.
Much like the swivel attachments in the ERS Series, Hilman Turntables are an accessory designed to integrate with Hilman OT and NT Series Rollers in order to allow users to accomplish turns. As well, custom Turntable assemblies can be designed and made for a variety of application for most any series of Hilman Rollers. The Hilman XYS Series roller is really two rollers, mounted top plate to top plate, with a turntable between them.
Radius Rollers are specifically designed to move on a fixed radius. The roller design utilizes a tapered keyway chain that serves as an internal alignment feature, as well as an Accu-Roll Guidance system (Type R and Type U) to minimize the effect of the external horizontal force. Minimum capacity is 37.5-ton and the minimum radius is 6 meters.
Wiper systems are optional on practically any roller. These will serve to clear the path of movement and prevent small debris from impeding the roller’s performance.
Hilman Elastomeric Preload Pads, used on top of or built into the top of individual Hilman Rollers serve to cushion the load while it is being moved. These replaceable pads are made of a high durometer neoprene that makes then strong yet resilient. The fact that the pads are pliable under heavy loads while providing a non-slip surface at the base of the load allow the roller footprint to conform with minor imperfections in the rolling surface. This pliability provides the user with the dual benefit of reducing the metal-to-metal slippage that can occur when moving a large piece of metal based equipment and allowing the movement of heavy loads over less than a perfect floor surface.
A Flex-Mount Fabric Preload Pad used with a Hilman Roller cushions the load over a long period. The replaceable pad is made with a fabric duct impregnated into and elastomer blend creating a high durometer pad which is both resilient and durable under heavy loading. In addition to providing protection at the base of the load Flex Mount Fabric Pads allow the rollers to move over a slightly out-of-level surface with comparative ease, while they remain under tension with the load. Hilman Flex Mount Fabric Pads have a low compression set with an excellent predictable spring rate.
