ALL TERRAINS Ӏ SECTOR REPORT
Link-Belt unlocks the lock
D.A. Collins Companies of Wilton, New York used their 275-ton Link- Belt ATC-3275 all-terrain crane, together with their 200-ton Link-Belt 248 HYLAB 5 lattice crawler crane to refurbish key components of a lock on the Erie Canal Lock in Niskayuna, New York this summer (2021). Valves, gates, electrical, and the concrete basin all needed attention.
After installation of sheet piling and draining the lock with a coffer
dam, DA Collins used the all-terrain crane to lower the crawler down into the dry lock to lift, remove, and position the 45 ton) lock gates for repairs. Tracks, body, and lattice boom sections of the 248 HYLAB were
lowered (and lifted back out at the conclusion) using the all-terrain. The 248 HYLAB rested on timber planks over a group of 2.1m tall Flexifloat barges that rose if prolonged rainfall flooded the lock. For operation inside the lock, the HYLAB was fitted with 90 ft (27m) of boom to ensure proper motion of the lock gates when they were lifted and moved for maintenance. Steel ramps on either side of the centred floating barge allowed the 248 HYLAB 5 to navigate the full length of the base floor of the lock. For anything beyond the perimeter of the lock footprint, the all-terrain was used to reach from above with its full boom and attachment. According to crane operator Bill Staley, “because of the ATC-
3275’s long (233ft, 67.9 m) reach and lift capability, I could reach any part of the lock easily.” The lock is 45 ft (13.7 m) wide by 328 ft (99.9 m) long. “This was the first time we had lifted our 248 into and out of a lock, so we communicated with our Link-Belt dealer, CRW Corp. of
j side roller blind on the driver’s door, improved instruments and modules as well as new displays make life more pleasant for the operator. A sun sensor detects strong sunshine and automatically adjusts the heating settings; lighting for the cab, superstructure, headlights and jibs is now by LED. The new DynamicPerform clutch module on the LTM 1110- 5.2 delivers almost zero wear starting and manoeuvring for the modular ZF TraXon gearbox, and without overheating. It transmits the engine power via an oil- cooled plate pack that runs in oil. The friction heat generated when starting is dissipated in the clutch oil and supplied to the vehicle’s cooling system. This way permanent and almost wear-free manoeuvring is made possible, claims Liebherr. A clutch protection function prevents

The Link-Belt 248 HYLAB 5 rested on timber planks over Flexifloat barges
Williston, Vermont to get correct information on the lifting points and recommended rigging needed to lift the house of the crane, the main transport load, properly.” The crane tracks were about 38,000 lbs (17 236 kg) apiece, and the rigged main crane body weighed 83,500 lbs (37 874 kg) and was lifted at a 36 foot (11m) radius on a 67 degree boom angle, with 103.4 feet (31m) of boom extended in the EM6 mode. The 40,000 lb (18 tonne) Flexifloat barges were one of the last lifts hoisted by the Link-Belt rig out of the dry chamber.
overheating of the clutch and the associated wear or destruction of the clutch under extreme load. Owners benefit from significantly extended service life of the drivetrain and drivers will have their workload reduced by the highly controllable clutch, Liebherr adds. Another farewell in the all-
terrain world is to the name of Demag. Tadano acquired Demag in 2019; in mid-October 2021 they announced that they would be sharing the same branding; the Demag name is now officially no more. The company has a new all-terrain, the first to be jointly developed by what used to be two separate teams, from Demag’s plant at Zweibrücken and Tadano’s at Lauf. It combines, therefore, the know-how of both German plants, and the expectation is that it will feature the best of both worlds.
The product is a two-axle 40t all terrain crane, the Tadano AC 2.040-1. It has a main boom of 35.2 metres and a maximum system length of 44.2 metres. Previewed in October, supply chain issues have delayed its launch slightly, to January/February 2022. With it Tadano introduced what they called the ‘joint DNA’ of their new all-terrain family. All new machines will feature common cabins, control systems, (The IC-1 Plus) and technologies, such as the Tadano Surround View system and IC-1 Remote telematics. Meanwhile, undelayed,
Tadano have delivered another first, its AC 7.450-1 all terrain crane to Wiesbauer – a company which has recently took over the cranes department of towing and recovery company Florian Herbold to become largest crane rental company in its region. f
