A seat operated parking brake assembly for lift trucks and the like normally imposes an overload force on a caliper-type brake thereof, after the brake has been engaged. The present invention provides an arrangement (34 or 34') for maintaining a brake (20) of this type in its disengaged condition when a seat (11) is maintained in a first position under the weight of an operator and for isolating continued movement of the seat (11) from the brake (20), after the brake (20) has been engaged in response to initial movement of the seat (11).

Seat-operated brake assembly with brake protection means

A vehicle frame has first and second members having adjustably telescoping channel portions securable by bolts disposed in selected combinations of holes provided in the channel portions for providing a total vehicle frame of a chosen length and wheelbase. Adjacent portions of the respective members define portions of a battery compartment which varies with the size of the vehicle frame to accommodate the power requirements thereof. Channel shaped spacers join facing portions of the members for increased strength of the resulting frame. A rear axle mounting assembly is adjustably mounted on the rear member for independent adjustment of the wheelbase. A second embodiment has front and rear members secured by a selected nestable spacer member having an adjustable axle mounting for independent adjustment of the vehicle frame and wheelbase.
