<p>SAFETY BRACE Provided is a brace for preventing a truck body from falling when raised above its chassis for maintenance, inspection or servicing. The brace includes a support column, one end of which is pivotally connected to a body longsill and the other end is retained by a release mechanism located on the body for holding the column in riding position. Provided on the chassis is a retaining means for securely retaining the column when it extends between the body (when raised) and chassis as a brace to prevent the body from falling. A stop means is provided for limiting the pivot angle of the column. The brace is installed in supporting position without an operator having to locate any portion of his body under the truck body while raised. This is accomplished by actuating the release mechanism to release the column. The body is then raised from remote control location and the column pivots until it abuts its stop mechanism which locates the lower end of the column above the retaining means on the chassis. Lowering of the body then joins the column and retaining means to form a brace structure which prevents the body from being further lowered.</p> |
