The LU-TS33-B switch and crossing grinder has been designed to carry out a number of different grinding operations on track. The grinding machine can be used in a two configurations to remove rail defects such as field and gauge side lipping, corrugation removal, rail head profiling and head defects. The P&C grinder is powered by batteries (48v DC) and is modular in its design. The two grinding heads are detachable as is the battery pack thus reducing overall weight for the benefit of manual handling.
The lipping head has a vertical grinding wheel used to remove lipping (field and gauge) and profile the face of a switchblade with a range of movement. The profiling head is a single cup stone rail head profile machine that grinds the rail from the gauge face across the head to the field side. Both heads are powered by a BCU that contains within its PELI protective casing 4 no. 12v batteries, motor controller and relays. External to the case is an E Stop, battery condition monitor and 110v socket for recharging. The batteries are arranged to supply 48 volts DC, with a maximum discharge current of 100A (providing a maximum power of 5kW).
