NEWS Link-Belt Announces
RELEASE New TCC-1200 &

Wireless Remote Control

LEXINGTON, KY. – To better meet customer demands, Link-
Belt Cranes has announced an upgrade to base rating of its
110-ton telecrawler to 120-ton. Shipments of the new TCC-
1200 will begin fourth quarter 2018.

The TCC-1200 offers an impressive capacity chart at
radius that rivals even lattice crawler cranes with a similar
base rating. The TCC-1200 is a full power boom, fabricated
from ultra-high-strength steel and formed in Link-Belt’s own
formed boom facility. The main boom height is 40 - 150 ft.
(12.2 - 45.7 m) long and incorporates Teflon wear pucks to
eliminate boom grease. It will come with three track widths
– extended [18 ft. 2 in (5.5 m)], intermediate [15 ft. 8 in. (4.8
m)], and retracted [11 ft. 11 in. (3.6 m)] which offers varying
footprint capability in popular telecrawler sectors such as
energy, industrial, and infrastructure.

Wireless Remote Control

An optional wireless remote control system is now available
for the new TCC-1200 and TCC-1400. The wireless remote
provides a solution for industries and other operations where
required, and allows the operator to be out of the cab and
still have control of the crane. n

fully raised spud, preventing it from free-falling if the winch
or cable fails. Preventing Accidental Deployment of Spuds
To ensure the safety of employees on construction barges

and towing vessels, employers and employees need to take
the following safety precautions:
• Before a barge is moved, the spuds need to be raised so

that the pinhole is above the resting area of the securing
pin. Each spud should be pinned in the raised position.
• The licensed master of a towing vessel, who is responsible
for ensuring that the vessels under his or her control are
safe to move, needs to ensure that spud securing pins
are in place and have a means to prevent inadvertent
disengagement before the tow is underway.
• If the spuds must be lowered to stop the barge in an
emergency situation (for example, in case of a power
failure of the tug or an imminent collision), a supervisor
needs to direct the barge employees on how to lower
the spuds.
Before attempting to lower mooring spuds, ensure that
spud securing pins are completely removed and that
employees are clear of the immediate area. Such practices
will help to avoid employees being struck by dislodged or
falling pins, which can weigh up to 85 pounds and measure
approximately 4-feet-long and 3 inches in diameter.
• Employers who own and operate barges need to
develop standard operating procedures. Employers
should provide and periodic training to employees on
barges including, how to use securing pins to hold spuds
safely in place before a barge is moved from one site to
another. n

Fire aboard the Athena 106, West Cote Blanche Bay,

On October 12, 2006, the towing vessel Miss Megan was

pushing two deck barges to a pile-driving location in the
West Cote Blanche Bay oil field off the Louisiana coast.
While the vessels were under way, the 5-ton aft spud on one
of the barges, the Athena 106, suddenly dropped into the
water from its raised position. The spud struck a buried high-
pressure natural gas pipeline, rupturing the pipeline. The
gas ignited and created a fireball that engulfed the towing
vessel and both barges. The master of the towing vessel
and four barge employees were killed, and another barge
employee was listed as missing.
