1) READ THIS FIRST
a) GENERAL
i) This Installation, Operation, and Maintenance manual is considered an integral part of the Carbis
equipment to which it applies. It is the Owner’s responsibility to ensure that personnel who operate and
maintain the Carbis equipment receive comprehensive training in the operation and maintenance of the
equipment, including adjustments where required. Operating and Maintenance personnel must also be
familiar with the basic characteristics of the equipment so as to avert errors that might result in equipment
damage or personnel injury. It is also the Owner’s responsibility to ensure that maintenance activities are
appropriately documented, including any abnormal operating condition and its associated root cause
evaluation, followed by corrective actions implemented to eliminate recurrence.
ii) Aging of equipment and associated service life-limiting variables, such as corrosion, fatigue, wear, etc.,
must be remedied during maintenance periods to preclude operational failure.
iii) While this manual provides guidance to operating personnel in the matter of safe operation and
recommended practices, it is not, and cannot be, a substitute for well-trained operations personnel. For a
successful and trouble-free operation, great reliance must be placed upon the knowledge, background,
and experience of the operating personnel, with this manual serving as a guide. The warranty on the
equipment is automatically voided if the information contained in this manual is disregarded, whether
inadvertently or willfully.
b) VEHICLE POSITIONING
i) Carbis gangways are designed in a variety of standard styles, sizes, and materials to accommodate
customer-specific requirements in applications that include varying heights and types of vehicles.
Subsequently, with each gangway, Carbis provides customer-approved Engineering Drawings and/or scope
data that document key dimensional relationships between the vehicle and the gangway, including safety
cages where applicable. Refer to the specific customer-approved Final Drawings for familiarization with
the dimensional relationships between Carbis equipment and the vehicle to determine the necessary steps
required to position the vehicle for proper operation.
ii) RAIL CAR POSITIONING
With the centerline of the rail car being a fixed, constant relationship with Carbis equipment, the only
remaining position that requires operator input is the position of the rail car along the length of the track.
With Carbis’ standard gangways, the rail car is generally spotted with the access area centered on the
gangway. With Carbis’ pivoting or tracking gangways, the rail car is generally spotted with the access area
contained within the pivoting or tracking range of the gangway.
iii) TRUCK POSITIONING
See the specific customer-approved Final Drawing and/or scope data for the dimensions required to spot
the truck for proper operation. Given the portable nature of the truck, the proper spotting is largely
determined by the skill of the truck driver; therefore, the use of visual spotting aids such as bollards, curbs,
painted guide lines, suspended markers (i.e., tennis balls), etc. can enhance the driver’s skill in spotting the
truck. See FIGURE 1-1 below for the effects of variable truck spotting positions.

4) PRODUCT DESCRIPTION:
MANUALLY OPERATED TCG-2500 GANGWAY
SEE PROJECT-SPECIFIC DRAWINGS, FIGURES WITHIN THIS SECTION,
AND SECTION 11) DRAWINGS AND SPECIFICATIONS
a) GENERAL
The TCG-2500 Series Gangway is a manually operated, spring-assisted, articulating gangway that provides safe
access to the tops of various types of truck and rail car vehicles of varying heights for operators to safely
perform the work required on the vehicles within fall protection enclosures that are typically associated with the
gangway.
i) The TCG-2500 Series Gangway requires assembly before use. See section 5) ASSEMBLY for instructions.
ii) The load capacity for Carbis series TCG-2500 gangways is 500 lbs.
b) MECHANICAL EQUIPMENT
See FIGURE 4-1 below.
i) GANGWAY
The TCG-2500 Series Gangway includes the following features:
(1) A galvanized steel base tread that is either fixed mounted directly to a platform, horizontally pivot
mounted, or track mounted
(2) The gangway consists of stringers that articulate about the base tread and top handrails and midrails
that pivot about the base tread uprights. The outboard uprights support the outer end of the top
handrails and midrails, and serve as a support for safety cages or seatainer treads. Walk surface
options are open serrated metal plank, fiberglass, or serrated bar grating, and are so noted on the
Final Drawings. Gangway material options, as designated by the letter in the model number noted
on the Final Drawings, are:
(a) A – Aluminum
(b) S – Mill Steel
(c) P – Primed Steel
(d) G – Galvanized Steel
(3) A platform extension with an extension handle is mounted under the main gangway walk surface,
and telescoping handrails are mounted on the top handrail.
(4) Bumpers mounted on the bottom leading edge of the stringers give added protection against vehicle
damage.
(5) A foot lock mounted on the base tread holds the gangway in the upright stored position. For
gangways without foot locks, the use of chains noted below are required to hold the gangway in the
stored position.

REVISED 5/19/2017 © SAM CARBIS SOLUTIONS GROUP, LLC, 2017, WITH ALL RIGHTS RESERVED PAGE 11
(6) Adjustable chains that are attached to the stringers and supported by slotted tube chain locks on
the base tread uprights hold the gangway in any desired position within the normal working range
of 15 degrees above to 15 degrees below horizontal. The range may be modified within the limits to
accommodate options. The slotted tube design keeps the chain locked throughout the full range of
gangway movement from the lowest working position up to the fully raised stored position. The
chains add strength and stability to the equipment while allowing a variety of vehicles to be
accessed. The chains should be used for overnight or long-term storage of the gangway.
(7) Covered springs mounted between the uprights and the stringers provide tension adjustment to
minimize the push/pull force required to articulate the gangway.
(8) A pull-up rope aids in returning the gangway to the upright stored position.
(9) For any gangway used in concert with elevating cages, platforms, and Modals, additional grab rails
are employed perpendicular to the outboard uprights each side of the gangway to cover the gap
created by the opening in the inboard handrail that accommodates the gangway.
(10) Each gangway includes a specific serial number located on the inside end of the right stringer
toeboard and is visible when the gangway is stored.

ii) TCG-S910.1 TRACK LOCK MECHANISM
See FIGURE 4-4 below.
Any TCG gangway that includes the track and carriage option also includes the TCG-S910.1 Track Lock
Mechanism, which is a safety device designed to prevent a manually tracked gangway from being rolled
along the track when the gangway is not in the upright stored position. The mechanism consists of a
combination of both automatic and manual lock functions as described below. NOTE: There is a
patent/patent pending for the TCG-S910.1 Track Lock Mechanism.
(1) The automatic function of the mechanism consists of the following features:
(a) The TCG-S910.1 Track Lock Mechanism is an assembly that contains a housing with a curved
release lever arm on one end and a brake pad pivot arm on the opposite end. The two arms
are sandwiched between and bolted to the side plates of the housing at the upper pivot point
of each arm. Bolted between the arms below the housing is a pair of flat bar spacers that allow
the arms to pivot together. Pinned between a bottom extension on each arm is an extension
spring that changes the geometry of the top end of each arm as the spring is extended or
released.
(b) The assembly bolts through holes in the side plate of the gangway base tread. The top of the
curved release lever arm includes a bent leg that engages with the top edge of the gangway
stringer as the gangway is raised to the stored position. The brake pad on the brake pad pivot
arm engages with the outer surface of the track on which the gangway rolls.
(c) As the gangway body is raised to the stored position, the stringer engages the bent leg of the
release lever arm which causes the spring to extend. As the spring extends, the brake pad pivot
arm pivots which causes the brake pad to disengage from the track. With the gangway fully
raised in the stored position, the brake pad is released from the track which allows the
gangway to be manually tracked.
(d) Whenever the gangway is deployed in any position that is not stored, and the release lever arm
is disengaged from the stringer, the spring causes the brake pad to press against the track,
thereby preventing the gangway from tracking while deployed.
(2) Whenever the gangway is stored, the automatic lock function of the track lock mechanism is
inactive, which allows the gangway to freely roll along the length of the track. As an added safety
feature, the track lock mechanism includes a manual track lock lever that is only deployed when the
gangway is in the stored position and not being used. When engaged, the manual track lock lever
causes a second brake pad to engage with the track, which prevents the gangway from being
inadvertently rolled along the track by any external force such as wind.

FIGURE 4-4
d) OPTIONAL TCG PIVOT MOUNT
See FIGURE 4-5 and FIGURE 4-6 below.
i) The pivot mount system consists of a gangway base tread with a male pivot post mounted on the
underside and a tread extension mounted on the platform side of the tread, and includes the following
features:
(1) The male pivot post engages with a female pivot-mounting sleeve and rests on a wear pad.
(2) The range of pivot rotation is 10 degrees each side of center.
(3) Brackets that are bolted or welded to a platform, either surface mounted or underslung below the
platform structure, support the female pivot-mounting sleeve.
(4) The pivot-mounting system can also be modified to retrofit an existing pivot support bracket.
