ENGLISH
The Class 5010 WB brake is a spring-set, electrically released, shoe-type
friction brake. It is designed to meet AISE Standard No. 11 and NEMA
Standard ICS 9 Part 1 for torque rating, wheel diameter, mounting
dimensions, and electrical operating characteristics.
Table 1 shows the maximum brake torque ratings. The torque setting for the
standard brake can be adjusted down to 50% of the maximum rating. A half-
torque spring is available which limits the maximum torque to 50% of the
ratings listed and provides adjustment down to 25% of the ratings listed.
The Class 5010 WB brake, when used with either AC or DC motors, provides
a fixed torque for holding or stopping the drive. The brake is supplied with
either a DC series-wound coil or a DC shunt-wound coil. Shunt-wound
brakes use a partial voltage coil and require connection of a shunt brake
resistor in series with the brake coil. AC applications require a rectifier control
panel (refer to bulletin 5010-16 for details).
DC series-wound coils are designed to release the brake at 40% of rated
motor current and to hold the brake released at 10% of rated motor current.
DC shunt-wound coils are designed to release the brake at 80% of rated
voltage and operate continuously at 110% of rated voltage. For application
information see Tables 2–4.

d. Loosen the manual release nut (F) and simultaneously raise the overlever
assembly (DD), gradually relieving compression in the torque spring (D).
Depress the spring-loaded latch pin (A), allowing the overlever assembly
to pass.
This section describes the adjustment of the armature gap, shoe clearance,
and brake torque. Letters in parentheses refer to Figure 1 on page 6.
The armature gap indicator (T) indicates the minimum and maximum
allowable armature gap setting. It is mounted on the frame near the bottom
of the magnet case (see Figure 3).
Figure 3: Armature Gap Indicator
On brakes not equipped with the self-adjuster, the stop nut (J) at the end of
the overlever assembly adjusts the armature gap. To adjust the armature
gap:
1. Turn the stop nut clockwise to reduce the armature gap.
2. With the brake set, adjust the stop nut so that the armature gap is at the
minimum setting. Use the jam nut (DD) to lock the stop nut (J) in place.
The self-adjusting brakes are designed to work with Square D factory brake
pads only. As the brake shoe wears, brakes equipped with a self-adjuster
automatically adjust to the correct armature gap/shoe clearance operating
gap. When initially setting up the brake, or after maintenance, manually

adjust the brake to the maximum gap indicated by the armature gap indicator
(T). This allows the brake to adjust to the correct armature gap.
Adjusting the armature gap also adjusts the shoe clearance. With the
armature gap at the minimum setting, shoe clearance between the wheel and
the brake shoe lining (L) is 1/32 in. Brake shoes automatically self-align for a
uniform gap between the shoe and the wheel. Operate the brake and check
for proper shoe clearance.
The brake torque setting is read directly from the torque calibration plate,
mounted next to the operating spring on the yoke.
Be sure that the brake is set before adjusting the brake torque. Adjust the
torque to the desired value by turning the adjusting nut (C). This varies the
length of the operating spring (D). Use the jam nut (B) to lock the adjusting
nut (C) in place.
This section describes items on the brake that may require periodic
maintenance. Inspect these items regularly. The brake is supplied with oil-
impregnated bearings that do not normally require lubrication in most
environments. Grease fittings are available as an option (standard on 19'' and
23'' brakes), and are recommended for brakes used outdoors or in high
temperature environments.
OSHA code requires the inspection of brakes at 1-month to 12-month
intervals, depending on activity, severity of service, and environment of the
brakes. The code specifically lists the following items for inspection:
deformed, cracked, or corroded members; loose bolts; worn, cracked, or
distorted parts. (OSHA code of Federal Regulations Part 1910.179 J2 and
J3.)
Depending upon the application and environment, wearing parts may require
more frequent inspection. It is your responsibility to determine appropriate
inspection intervals.
As linings wear, the armature gap increases. With the brake set, the armature
gap is correct when the inside of the armature aligns with the inside edge of
the slotted step of the armature gap indicator (T). The maximum allowable
gap is indicated by the outside edge of the slotted step of the armature gap
indicator (Figure 3). The stop nut (J) must be readjusted before the armature
gap reaches the maximum allowable limit.
A hex nut (M) on the shoe assembly acts as a gauge to indicate shoe lining
wear. Replace the lining when its wear surface is even with the top edge of
the hex nut (M). Brake shoe removal does not affect the torque setting.

brake size.
6. Readjust the armature air gap as explained in “Shoe Clearance” on
page 9.
7. Loosen the manual release nut (F) to its original position and secure with
the cotter pin (G).
The coil and coil core are encapsulated. The operating coil is removed from
the rear of the magnet case. When the coil is removed, the brake settings do
not change and the brake does not need to be released. Normally, it is not
necessary to remove the brake to change the coil.
To remove the coil from the magnet case, perform the following steps in the
order listed:
1. Disconnect power to the brake.
2. Disconnect the coil leads.
3. Remove the six hex-head cap screws (V) from the outer edge of the
magnet case cover.
4. Screw two hex-head cap screws (V) into the threaded blind holes in the
magnet case cover. This will break loose the magnet case cover and coil
core assembly from the magnet case. See Figure 4.
5. A lifting hole (X), located on the magnet case cover, aids in removing the
coil assembly. Slide the coil and core assembly out of the magnet case.

shaft:
1. Disconnect power to the brake.
2. Manually release the brake by removing the cotter pin (G) from the
manual release nut (F) and tightening the manual release nut until the
armature completely closes.
If replacing the brake wheel and motor armature as a unit, disassemble the
brake according to Method 2 of “Relieving Torque Spring Compression” on
page 7.
Replacement of the frame bushings is recommended during a complete
brake overhaul. Remove power to the brake and secure the load before
removing the brake from the crane.
Perform the following steps to replace the frame bushings:
1. Press out the four stainless steel frame bushings.
2. Press in new bushings (use of the pilot device is recommended).
3. Ensure the lever pin rotates freely.

ENGLISH
This section contains instructions for disassembling the self-adjusting shoe
mechanism, overlever assembly, armature, and connecting rod lever.
Remove power to the brake before performing these operations.
If the brake is equipped with the self-adjusting shoe mechanism, it can be
removed by following step 7a on page 6.
Before removing the overlever assembly, relieve the compression of the
torque spring (D) using either method in “Relieving Torque Spring
Compression” on page 7.
To reassemble the overlever assembly:
1. Simultaneously tighten the manual release nut (F) against the yoke (E)
and lower the overlever assembly.
2. Ensure that the flange on the manual release nut passes through the hole
in the yoke and the torque spring (D) is seated on the yoke, to allow the
overlever assembly to pass.
3. Loosen the manual release nut (F) to its original position and secure with
the cotter pin (G).
To remove the armature and connecting rod lever, or to gain access to the
lower pins and bearings, perform the following steps in the order listed:
1. If the brake is equipped with the self-adjusting mechanism, remove the
self-adjusting connecting rod by removing the hex-head cap screws,
washers, lock washers, and nuts.
2. Relieve the compression in the torque spring (D) using either method in
“Relieving Torque Spring Compression” on page 7.
3. Disconnect the centering bracket (BB) by removing the cotter pins, nuts,
and springs (Z).
4. Remove the locking pin and the armature pin (AA).
5. Remove the locking pin and the inboard shoe pin (CC).
6. Remove the stop nut (J) from the end of the overlever assembly.
7. Lift the armature, inboard shoe assembly, connecting rod lever, and
overlever assembly from the brake.
When supplied, the self-adjusting shoe mechanism automatically
compensates for shoe lining wear. During normal operation, a ratchet type
assembly, coupled to the armature, automatically adjusts the armature gap
as the shoe linings wear. The standard brake is machined so that the self-
adjusting mechanism can be added as a field modification. Refer to the
bulletin furnished with the self-adjusting mechanism kit for detailed
installation instructions. The self-adjusting shoe mechanism does not require
lubrication.
After the initial brake installation or when replacing the brake shoes, adjust
the shoe clearance and the armature gap:
DISASSEMBLY
STORED ENERGY HAZARD
The torque spring is under compression.

ENGLISH
Back off the starwheel stop nut located at the end of the overlever assembly,
until the armature gap is at the maximum allowable setting, as indicated by
the armature gap indicator (T). Manually hold the ratchet rod away from the
starwheel nut while making this adjustment. The self-adjuster will
automatically readjust the armature gap/shoe clearance gap to the correct
setting.
To check for proper assembly of the connecting rod and ratchet rod:
1. For proper operation, the length of the connecting rod, as measured
between the centers of the pivot points at the ends of the rod, should
match the length listed in Table 6.
2. Tighten the connecting rod screws to the torque value listed in Table 6.
There must not be any play between the screw head and bearings.
3. With the brake manually released (armature closed), verify that the
location of the top of the ratchet rod relative to the brake connecting rod
is as listed in Table 6. Ensure the spring holds the ratchet rod firmly
against the starwheel stop nut.
4. The ratchet rod must not be tightened snug to the crank assembly.
Tighten the ratchet rod screw completely, then loosen by one-third turn
(0.025'' clearance). Tighten the jam nut.
Set up the brake using one of two armature gaps, normal or wide. The
orientation of the connecting rod positioner in the crank assembly determines
the armature gap setting. When the brake wheel is subject to wide
temperature variations during operating and cool-off periods, the wider
armature gap may be required to maintain a 1/32 in. minimum shoe
clearance.
To adjust a normal armature gap:
1. Disconnect all power.
2. Install the conecting rod positioner with the larger (1/2 in.-13) tapped hole
positioned closest to the crank assembly pivot pin, refer to Figure 10 on
page 23 and Figure 11 on page 25. This sets the lever arm ration to the
minimum position.
When the self-adjuster overtightens (due to low ambient temperature) and
results in an armature gap less than 1/32 in. adjust a wide armature gap.
To adjust a wide armature gap:
1. Disconnect all power.
2. Rotate the connecting rod positioner 180°. This creates a larger lever arm
ratio, resulting in a larger armature operating gap.
Troubleshooting information can be found on page 26.
