General - Purpose Stand for Car's Brake Test Type USBHW

USBHW-5 - automated pneumatic, inspection-measurement device is applied for acceptance tests of braking systems of freight and passenger cars and other rail vehicles with distributor valves of the following systems:

USBHW-5 - inspection-measurement device, which:
  • simplifies test process of car's braking system
  • enables to carry out test series of car's braking system and other car's pneumatic systems in automatic cycle according to the obligatory rules of UIC 540, UIC 541-04, UIC 547 and UIC 543.1
  • reduces test time to necessary minimum owing to automation and optimalization of measurement process
  • increases reliability of pneumatic braking systems of traction vehicles owing to the accurate and repeatable measurements of the inspected parameters
  • eliminates so-called human factor and enables the objective estimation of the state of car's braking system and distributor valve on the car
  • reduced number of railway stock units out of operation in consequence of the defects in pneumatic systems and electric and mechanical systems directly connected with these pneumatic systems: e.g. bogie
  • reduces employment to 1 operator, who executes all activities.
