The belt conveyor of a tunnel boring machine has to transport the excavation material.
To secure the necessary belt tension, two drives are working with different speed against each other. That causes braking energy in one of the two drives.
The brake energy has to be managed safely and quickly with an external brake resistor.
Our resistor combination BAS4.8010D-1000H (4,8 kW / 15 Ohm / IP20).
The brake energy is managed safely and quickly.
