Dynaswitches &

Reeving Setups

Below are some examples of hoist and reeving setups which use the

Dynaswitch for control and/or safety purposes.

Figure 2-A

2 ropes, 2 part single

reeving

With two parts of line to the hook,

the Dynaswitch should be installed

in series between wire rope and its

dead end point. Microswitch is set

for ½ maximum capacity of the

hoist.

Figure 2-D

The Dynaswitch may also be placed

between hoist and trolley with

microswitch set for maximum

capacity of the hoist and trolley.

Figure 2-B

Figure 2-C

4 ropes, 4 part single

reeving

As shown at right, Dynaswitch is

installed in series with rope to the

dead end. The microswitch is set

for ¼ capacity of the crane because

there are four parts of line to the

hook.

Frictional reactions within the

sheaves may prevent all parts

of the lines from having identi-

cal tension. While generally

suitable for overload protection,

it may give unsatisfactory

results for weighing or batch

control.
