Operation
Rotating upper carriage
Upper carriage hydraulic brake:
The upper carriage's rotation is sufficiently braked by moving control lever
back to initial
position. Moving the control lever in the opposite direction (counteraction) brakes the
upper carriage with maximum hydraulic output.
Upper carriage mechanical brake:
This is a multi-disk mechanical brake that provides a secondary service brake and a pri-
mary parking brake function for the upper carriage. It is operated independently from the
hydraulic brake of the upper carriage.
Important!
The mechanical brake functions only to prevent upper carriage rotation. It does not
function as a machine propulsion brake.
