Abstract: A system for monitoring and/or controlling equipment in a hazardous area can include at least one sensor disposed within the hazardous area. Each sensor can be non-electrical and can be adapted to interact with the equipment and generate at least a first sensor output and second sensor output. The first sensor output can be indicative of a first equipment state and a second sensor output can be indicative of a second equipment state. The system can also include at least one converter disposed outside the hazardous area. Each converter can be in communication with at least one of the sensors. Each converter can be configured to receive the first and second sensor output and generate a converter output signal based on at least one of the first and second sensor outputs.

Abstract: A vehicle lift system includes a support structure having a top surface for supporting a vehicle supported by the vehicle lift system, and at least one lighting module. The lighting module is mounted to the top surface of the support structure. The lighting module is configured to illuminate a region of the vehicle, for example, but not limited to, the underside of the vehicle. The lighting module can be mounted generally flush relative to the top surface of the support structure. In a vehicle wheel alignment lift system, the lighting module can be disposed adjacent a movable support surface of the wheel runway apparatus to provide illumination during wheel alignment procedures.

Abstract: A first apparatus for supporting a wheel of a vehicle includes a support structure and a support movably mounted on the support structure. At least one locating member and clamping mechanism are mounted to the support structure and the support. The clamping mechanism engages the locating member so that the support is held in a predetermined position relative to the support structure. A second apparatus for supporting a wheel of a vehicle includes a bearing surface and a support movably mounted on the bearing surface. A first locating member is positioned underneath the bearing surface, and a shaft is mounted to the underside of the support and extends through the bearing surface and the locating member. When an actuator is retracted, the first locating member bears against the bearing surface so that the support is held in a predetermined position relative to the bearing surface.
