HYDRAULIC SCHEMATIC

The TWG 250PR is equipped with a spring applied hydraulically released static "park brake" and an

optional integral hydraulically applied dynamic "service brake". The park brake on this unit should

full release by pressurizing the "BR" port to 300 psi. The maximum pressure allowed into the park

brake is 3,000 psi. The service brake is applied by pressurizing the "BA" port while pressurizing the

"BR" port. The maximum pressure allowed into the service brake port is 1,000 psi. The service

brake can be cooled using a flow-thru cooling method by plumbing hydraulic oil into "BC IN" port

and plumbing "BC OUT" port back to tank. The maximum pressure allowed in the brake cavity (flow

thru cooling circuit) is 25 psi. Excessive pressure in the flow thru cooling circuit could damage the

oil seal separating the brake oil from the gearbox oil.
