摘要：The paper contains the designs of modifcations of testing devices, which were constructed for the purpose ofchecking the functional properties of the mechanical pallet fxing lock built by the KOMA – Industry s.r.o. company, which is used for securing pallets with cars in parking houses. The individual testing devices consist of oneor two positioning devices, the moveable parts of which are placed perpendicular to each other in the frame ofthe testing device. A mechanical pallet fxing lock is attached to the moving part of the perpendicular positioning device, and it consists of the following three parts: the body, the pulley holder and a compression coil spring.A plate is attached to the moveable part of the horizontal positioning device and is adapted to receive a pressureforce sensor or to engage a mechanical fxation lock or the break of an electromagnetic locking device. The papercontains the description and method of experimentally determined resistance, which is created by the shear frictionon contact surface, when inserting or withdrawing the pulley holder tube from the plain bushing of the fxationlock body. Additionally, the paper provides the values of the measured vertical forces, which are generated bythe deformed compression spring with a wire of circular cross-section during inserting/withdrawing of the pulleyholder tube into/from the fxation lock body. The values obtained from the performed experimental measuring ofvertical forces and frictional resistance during the inserting of the pulley holder tube into the plain bushing of thefxation lock body will be used for subsequent checking of the functional properties of pallet fxation locks andwill allow determining the optimal position for attaching the pallet fxation locks to stack cell steel beams in theparking house, on which chain conveyers push pallets with cars are parked.
