Strata Safety Refuge Chamber Wheel and Hitch Package
In order to assist moving the chambers into and around the mines and in restrictive areas, Strata Safety has engineered a robust wheel and hitch package to be added during construction of the unit or retrofitted later. These additions will significantly reduce wear and tear during movement.
Coal Refuge Chamber with Wheel and Hitch Package.
Each chamber is fitted with four smooth, solid rubber wheels and six wheel mounts (three on each side). The choice of wheel mountings is relevant to the direction the chamber will be pulled. Placing the wheels next to each other on each side facilitates easier turning and placing the wheels on the end most mounts allows the Chamber to balance itself. The wheel location can be changed while underground. Standard ground clearance is 5 ½". Custom set up to increase or decrease ground clearance is available.
The chamber hitch is a removable drawbar supplied at varying lengths. The hitch can be used on either end of the chamber to facilitate pulling in either direction.
Removable draw barcan be customized to varying lengths.
