HOLLISTER-WHITNEY “ROPE GRIPPER®”
*** With 620-100 Pumping Unit ***
Instructions for Model #620, 622, 624, 625, 626 & 626SPL (Patent #5,228,540)
WARNING:KEEP HANDS CLEAR OF “ROPE GRIPPER®”.
FORCES CREATED CAN CRUSH FINGERS.
FIGURE 1
“ROPE GRIPPER®”MOUNTING CHANNEL GUIDELINES
•The Mounting Channel Framework supporting the gripper must withstand upward and
downward forces according to Chart 1 below and applicable codes. Hollister-Whitney does
not recommend anchoring “Rope Gripper’s®”directly to concrete.
•The Mounting Channel Framework must be sufficiently sized to securely hold the “ROPE
GRIPPER®” and elevator while preventing any sliding. The Traction Machine must also be
prevented from sliding. See Figures 2 and 3 for suggested machine room mountings.
Additionally, see Figures 11 thru 14 for examples of Hollister-Whitney machines with built-
in factory “Rope Gripper®”mounts.
•It is always recommended that the “Rope Gripper®”be mounted in the machine room.
However, it may not be possible to mount the gripper in the machine room when adding a
“Rope Gripper®” to an existing installation. It is acceptable to mount the “Rope Gripper®” in
the hoist-way, and it can be mounted horizontally or upside down on the car or counterweight
side, so long as proper consideration for access is given for future gripper maintenance and
Pumping Unit location. The Pumping Unit must be mounted right side up. The hydraulic
hose standard length is 27 inches. Various hose lengths of up to 8 feet are available in stock,
with longer lengths up to 30 feet available by special order. The available lengths can be
utilized to mount the Pumping Unit in the machine room if the “Rope Gripper®”is mounted
remotely such as in the hoist-way.
•Note: If the “Rope Gripper®”is mounted upside down, consideration should be given to
covering the “bottom”of the mechanism to help prevent dirt and debris from falling into the
“Rope Gripper’s®” internal workings.

Note: Mounting must conform to applicable codes. CHART 1
•Position the “ROPE GRIPPER®” so that the stationary shoe lining barely touches the ropes
from top to bottom. Make sure the gripper is squarely aligned, and centered side to side as
much as possible, with the ropes. Misalignment may cause uneven and/or excessive lining
wear. Note:
oIn some cases, rope orientation may twist through the hoistway, such as when the
overhead and car sheaves are not aligned. In this case, some “misalignment”to
the stationary pad is necessary. This is acceptable so long as the ropes clear both
pads while traveling.
oRope splay near the hitch may cause additional alignment challenges. In these
cases, rope clamps such as H-W’s Rope Guide (P/N 270-109) may be utilized.
•Securely fasten the gripper mounting bolts (5 bolts per side). Torque to specifications in
Chart 1 above. * Note: The 6 5/8" bolts supplied with the 626 and 626-SPL Grippers
ONLY securing the mounting angles (3 per side) to the Gripper are Grade 8 and should be
tightened to 225 ft-lbs.
•Double check rope alignment. Notes above notwithstanding, the ropes should touch the
stationary shoe lining evenly if applicable.
•Reinstall movable shoe assembly.
•Reinstall connecting arms with chamfered edges facing inside the gripper and secure the four
snap rings.
•Mount pumping unit in the best available location. Unit must be upright but can be placed on
either side of the gripper. See hose length notes on Page 4.
•If necessary, wiring on the gripper can be rerouted to opposite side of assembly by relocating
the box connector to the opposite side and pulling wire through.
•Remove the pumping unit knock-out for the hydraulic line, install the supplied Rubber
Grommet and route male hydraulic fitting through knockout hole on the side of pumping
unit. Inside pumping unit push male Quick-Connect fitting into female fitting while lifting

BULLETIN 1144

ring on female fitting. Release ring to secure the fittings together.
•Wiring from the gripper to pump unit is color coded per Chart 2.
•Connect terminals RG1 and RG2 to controller power, RG5 and RG7 to
safety circuit; check control diagram for proper elevator control connection.
•When wiring and hydraulic connections are complete, make sure valve stem
(dump valve) in pumping unit is set to AUTOMATIC. Turn pumping unit
test switch ON (see Figure 4). The gripper latch solenoid should energize
and push the trigger onto the latch. If it fails to do so, check control wiring.
•When the solenoid is energized, loosen the two security set screws a turn or
two. If rotating shaft moves, turn valve stem to MANUAL and use hand
pump to move shaft back, or jump terminal RG3 to RG4 to temporarily
operate electric pump. Make sure the trigger has properly engaged the latch.
•Remove security set screws. Once removed, store set screws in bottom of
pump unit. NOTE: Security set screws must be completely removed
when “ROPE GRIPPER®”activates to prevent gripper failing to set or
damage to the unit.
•Unit is now ready for required lining wear-in and testing.

TESTING OF “ROPE GRIPPER®”
•Make sure controller safety circuit is active and clear for running, and the pumping unit valve
stem is in AUTOMATIC. Turn test switch ON. The “ROPE GRIPPER®” should be in the
ready (LOADED) position (NOT gripping the ropes).
•Turn test switch to OFF. This should activate the “ROPE GRIPPER®”, gripping the ropes.
Be sure that while gripping the ropes, the switch contacts on the “ROPE GRIPPER®” stop or
prevent power from being applied to the motor and machine brake.
•Turn the valve stem in the pumping unit to MANUAL. This will open the manual
microswitch contact and prevent the elevator from running.
•Use hand pump to return the gripper to the ready or loaded position.
•Turn test switch ON. Elevator should still be prevented from running.
•Turn the valve stem back to AUTOMATIC. The manual contact will close allowing the
elevator to run.
“ROPE GRIPPER®” LINING WEAR-IN
1. A line has been marked on the side wall of the gripper to aid in the Wear-In process. Note
that at this point in the procedure, this line is well above the Connecting Arm and will be met
or covered by the Connecting Arm during the Wear-In process (refer to Figures 1 & 5 for
location of Connecting Arm and Wear-In line).
FIGURE 5
2. Confirm the moveable shoe has been set up for the proper size ropes (Chart 3). Shims on
this chart are a general guideline and may vary. See Item 9 of this section.

BULLETIN 1144
Page 10 of 29
11/12/19
3. Make sure pumping unit valve stem is in AUTOMATIC and test switch is ON.
4. Run the car at the slow or inspect speed and wipe down the ropes to remove any dirt and/or
excess oil and grease from top to bottom. Return car to top floor.
5. Jump terminals RG5 to RG6 and run the empty car in slow speed in the direction that will
pull the ropes thru the “ROPE GRIPPER®”(typically DOWN). When the car is up to speed,
turn the test switch OFF. The “ROPE GRIPPER®”will grip the ropes with a light pressure
and ropes will begin to wear grooves in the linings.
6. As the linings wear-in, the rotating shaft will move up the cam slot and around the corner(s)
of the cam noted below (Figure 6), and the connecting arms will move up the side wall and
begin to match or line up with the wear-in line (see Figure 5) marked on the side wall.
Note: #624, #625, #626 and #626SPL have two corners. These grippers are not worn-
in until the rotating shaft goes past the second corner of the cam as noted below (see
Figure 6) and the connecting arm meets or covers the line marked on the side wall.
FIGURE 6
7. Note that it may take several car-runs to complete lining wear-in.
8. Once the rotating shaft has turned the corner(s) and the wear-in line is matched or covered,
stop the car and remove the jumper from RG5 to RG6.
9. If the lining wear-in is not completed after the grooves in the linings have reached
approximately 1/16”deep, spacer shims (Figure 7) can be moved from between the shaft
support blocks and moveable shoe to the outside of the support block to allow the rotating
shaft to completely turn the corner and move up the cam. Refer to Chart 3 for initial spacer
and shim set-up. Note: Before changing spacers, install security set screws to prevent
unintended “ROPE GRIPPER®” activation, which could lead to severe personal injury
and/or damage to the unit.
LINING WEAR & REPLACEMENT
•The linings will wear, especially after multiple high-speed stops. When gripping moving
ropes, material will be removed from the pads (lining wear) and the rotating shaft will move
towards the upper end of the cam. Near the end of the cam, the excessive wear microswitch
will open and the “ROPE GRIPPER®” will not automatically reopen.
