Issued last month, Sandvik lays out in the bulletin details of a park/emergency brake retrofit kit and test procedure for battery powered machines.
The safety bulletin was prompted following a MICO park/emergency brake found in a dry condition in an Eimco Coal Hauler, despite being designed to be used wet with hydraulic oil as the coolant.
The bulletin affects all 508CS, 518CS, and 580CS battery powered machines and all MICO park brakes supplied under part number 3210166 by Eimco, EJC or Sandvik (MICO model number 13-547-420).
Sandvik said to prevent a failure, a park/emergency brake test valve must be installed on the machines; an approved mineral oil must be added to the brake sump; and the brake must be tested.
