Lifting the Assembly
❐ 1 Remove the enclosure (heat shield) from the DB resistor. Set
the enclosure aside.
❐ 2 Prepare the mounting location as described in the Dynamic
Braking Kit instruction manual (1397-5.15) which ships with
the Dynamic Braking Kit.
Preparations For Lifting
❐ 2 Insert properly sized and rated lifting hooks (or lifting bolts
with washers) into the end plate holes on the DB resistor
assembly (refer to Figure 1). To limit pull in forces on the
Dynamic Braking Assembly, the lifting devices connected
to the hooks must be long enough to make the angle between
the chain and a vertical line extending up from the assembly
edge less than 45 degrees, as illustrated in Figure 2.
Use the following procedure to lift the DB resistor assembly.
Figure 1 illustrates the main structural features of the DB resistor
assembly. Not shown, but supplied with this assembly, is an
enclosure which serves as a heat shield. It should be installed after
the DB resistor assembly is mounted and secured.
❐ 1 Check the hole pattern on the location where you will be
mounting the dynamic braking assembly.
