“Rollerbed Systems’ capabilities will meet or exceed your requirements.”

Air Systems

The Pneumatic Roller track, Powered Cargo Roller and the Slipchain loading system draw air from the vehicle's air operated wheel brake system to function . Air in excess of 80 PSI is tapped off from the main vehicle brake system and fed to an auxiliary tank(s) via a Pressure Protection Value, this valve maintains the integrity of the vehicle brakes and must always be fitted as part of a Rollerbed system.

System air is fed via plastic air tubes and push-in connectors from the auxiliary air tank(s) to a control box containing a pressure regulating valve and control valve. The incoming air is regulated to 28~32 PSI and controlled by a push-pull operated control valve. The number of regulator valves and control valves within the control box depends on the complexity of the system to be controlled and will be determined by the manner in which the customer wishes to use the system.

Slipchain system air control boxes generally contain at least two operating valves and two regulators to cope with the different pneumatic pressures involved. The operating valves can be push-pull or solenoid operated depending on the use of the trailer. In the case of Slipchain trailers the air control boxes are often externally electrically controlled and /or integrated into a factory or distribution center main logistics control program.

Every system is equipped with at least one air tank to store pressurized air for use by any ancillary system. Depending on the size of the system and the frequency of operation, additional air tanks may be required. In this situation two tanks can be utilized. There are occasions when  an emergency reserve is specified, then two tanks and a change over valve would be installed. In this case one full air tank can be segregated from the main system to ensure an air supply available when needed.

A Track Isolation Valve (TIV) assembly is included to provide an in-service benefit in the unlikely event of an airbag failure. Should an airbag develop a leak a specific valve on TIV can be selected to isolate the damaged airbag and permit the remaining air bags to be inflated normally.
