LIFT RESISTING DEVICE ADDENDUM
a)
GENERAL
i)
The TCG Gangway LRD (Lift Resisting Device) Lever Arm Release Handle instructions contained within this
addendum apply to Carbis Manually Operated TCG Gangway Series TCG-1000, TCG-2000, and TCG-2500.
ii)
The Lift Resisting Device is designed to impede the gangway from being inadvertently or prematurely
raised while the top of the vehicle is occupied by operating personnel. The Lever Arm Release Handle is
designed to release the LRD while simultaneously raising the gangway to the stored position as an
operator exits the gangway.
iii)
This addendum is considered an integral part of the instruction manual for the gangway to which the Lift
Resisting Device and Release Handle apply.
b)
DESCRIPTION
i)
The Lift Resisting Device consists of the following features:
(1)
A linear rail with ratcheting angled teeth mounted on the underside; the rail is pinned on one end to
a lug that is supported on the top rail of the gangway by double U-bolts. The opposite end of the
rail slides into an extension tube that is pinned to a support bolted to the outboard handrail of the
gangway.
(2)
Pinned to a lug mounted on the underside of the linear tube is a ratcheting pawl with a pivoting
catch that engages a tooth of the linear rail and holds the gangway in place, which impedes the
gangway lift.
(3)
The LRD Lever Arm Release Handle is designed to actuate with a pull-up rope that is supplied with
the LRD as shown in
FIGURE 10-1
. The Release Handle is mounted on the ratcheting pawl of the
LRD. When the handle is pulled towards the platform with the rope, it causes the ratcheting pawl to
pivot, which releases the catch from its engagement with the gear tooth of the rail and allows the
gangway to be raised to the stored position with the LRD rope.
