Vertical Forces Acting on the Lock‑Off Element of the Pallet Brake System

The paper presents an experimental device that was created in order to obtain the real values of the forces acting in the vertical direction on the lock‑off element, the so‑called brake body, the 2nd design option. The lock of this design is used in the automated parking garage, designed by KOMA – Industry, s.r.o, to lock the parked vehicles on pallets in the units of the rack parking system. The forces acting in the vertical direction on the body of the fixation lock when pushing the brake pulley into the circular recess in the brake ramp are theoretically calculated for two design variants of the brake ramp used in practice, i.e. “without” and “with” a rounded (filleted) circular recess segment in the brake ramp. The experimentally determined forces acting in the vertical direction on the brake body were determined for two types of compression coil springs with a rectangular cross section of the spring wire.
