Abstract: The present invention provides an improved electric drum brake (10). The electric drum brake (10) utilizes vibration absorbing mount (27) for positioning an electro-magnet (24) on the tang (22) of an actuating lever (21). The vibration absorbing mount (27) prevents metal-to-metal contact between the tang (22) and the electromagnet (24) and eliminates or greatly reduces road vibrations.

Abstract: A ramp/dock/loader apparatus comprising a ramp section pivotally secured in the proximity of a materials storage area and movable between a lowermost substantially horizontally disposed position to an uppermost substantially vertical position, a dock or platform section pivotally secured to the outer edge of the ramp section and pivotal simultaneously therewith but in an opposite direction whereby the platform section remains in a substantially horizontal orientation during angular movement of the ramp section, and fluid cylinder apparatus operably connected with the ramp section for effecting the pivotal movement thereof.

Abstract: An air over oil high pressure modulating valve comprising dual acting valve members wherein one of said valves is responsive to air pressure acting thereon for opening the other of said valves for directing controlled hydraulic fluid pressure to a brake apparatus, or the like. Upon the application of pneumatic pressure against the first valve member, the second valve member is opened for releasing hydraulic fluid pressure to the brake apparatus for actuation thereof. Upon the release of pneumatic pressure from the first valve member, the second valve member is maintained in a closed position for retaining the hydraulic fluid in a fluid chamber which is in communication with a fluid accumulator. When the pneumatic pressure acting on the first valve is only partially released, the first valve opens communication between the open second valve and the fluid accumulator for reducing the fluid pressure at the brake apparatus.
