Consult the Manufacturer for the traverse weight and other
required information before attempting installation.
Before installing traverse on bridge, lock runway
conductor disconnect switch in open (power
off) position.
Total weight of traverse and hoist should be checked
against lifting equipment selected for erection of traverse.
Immediately after traverse is placed on the traverse rails,
check wheel flange clearances to the rail. Clearance
between side of rail head and inside flange of wheel will
be 1/4" for a 40# ASCE traverse rail with wheel centered
on rail.
CONNECTING TRAVERSE TO ELECTRICAL
SERVICE: Traverse wiring diagrams are shown in
113533-78.
Verify that traverse is furnished for the same voltage,
frequency and phase as the traverse power supply.
Do not operate traverse until “Pre-Operation Checks”
below are made.
PRE-OPERATION CHECKS: After the hoist traverse unit
is connected to electrical service, the following pre-
operation checks should be made before operation:
1. Check collector system for proper adjustment to
maintain proper contact with conductors or check along
span for possible interference if power supply is cable reel
or festooned cable.
2. Make certain traverse stops have been installed and
that they are correctly located.
3. Check truck axles and oil level of motor gearhead
unit. If lubricant is required, see LUBRICATION on page
11.
4. Inspect the traverse to make certain all bolted
attachments are properly tightened and all electrical
connections are secure.
5. The hoist unit should be checked as instructed in the
Hoist Manufacturer’s Instruction Manual. Check to make
sure that traverse wheels have proper clearance to rails
for freedom of operation.
6. The traverse wheels and the flange surface of crane
rails on which traverse wheels roll should be free of paint
to provide proper electrical ground. If the environment in
which the crane will operate is such as to impair the
contact between traverse wheel and crane girder, an extra
conductor should be provided for grounding purposes.
NOTE: This instruction also applies to the bridge

TRAVERSE ARRANGEMENT
This manual contains important information to help you to
operate, maintain, and service the traverse arrangement
of your crane trolley. The hoist is covered in a separate
manual.
We recommend that you study the contents thoroughly
before putting the traverse into use. With proper installation,
application of correct operating procedures, and practicing
the recommended maintenance suggestions you will be
assured maximum service from your traverse.
The traverses described in this manual are intended for
indoor service. Traverses to be used for outdoor service
require special consideration.
IMPORTANT!
When ordering replacement parts be sure to include with
your order, the KEY NUMBERS, which are identified
elsewhere in this manual.
Information given in this manual is subject to change
without notice.
GENERAL DESCRIPTION
GENERAL: These traverses are designed to operate on
parallel bridge girders with 40# ASCE rails. Motor and
control are designed for 208V, 230V, 460V or 575V – 3
phase – 60 hertz power supply. The traverse is equipped
with a single or two speed motor controlled from a pendant
push button station. The push button may be located on
the bridge or hoist traverse unit. Traverses described herein,
are built in rated loads from 10 thru 25 tons.
BASIC CONSTRUCTION: The traverse frame is of rolled
steel welded construction. The frame consists of two trucks
rigidly bolted to the hoist.
The traverse is driven by a gearmotor attached to one
truck. The gearmotor drives the truck axle by a hollow
shaft keyed to the axle.
INSTALLATION
GENERAL: Bridge girders on which these traverses will
operate must be amply strong to support traverse, hoisting
equipment and rated load. Traverse rails should be level
and parallel within ± 1/4". Rail joints must be smooth and
held firmly in alignment either by bolted splice bars or
welding. Rails should be securely fastened to the bridge
girders.
INSTALLING: The installation of the traverse on the crane
shall be performed only by qualified installer.
For information regarding attaching, lifting and moving the
loads during installation, refer to ANSI B30.2.0, Section 2-
3.2 and other applicable codes.
