Link-Belt will debut the all-new 130-ton 228 HSL lattice-boom crawler crane at Conexpo 2017, March 7-11, in Las Vegas, Nev.
The 228 HSL builds on the legendary success of the job-proven Link-Belt HYLAB lattice-boom crawler line-up, and takes another step forward with easy transportability and attachment versatility. It also offers strong lifting capacity.
Easy transportation was a key requirement for the 228 HSL's design. The main load, complete with crawlers, hoist rope, and boom base, can be transported at less than 120,000 lbs. “There are markets that will appreciate the increased capacity with these transport weight options,” said Scott Knight, Link-Belt product manager for lattice and telescopic crawler cranes. Where needed, the main load can be reduced to less than 80,000 lbs. by removing the crawler frames.
Upper
The 228 HSL is powered by a whisper quiet, 270-hp Cummins QSB 6.7L Tier 4 Final diesel engine. The operator-selectable “auto idle” engine shutdown feature maximizes fuel economy during extended idling, and the engine revs back up immediately when the throttle is activated.
The Cummins power plant couples to a direct-drive gearbox that powers the Kawasaki main-pump package. “Link-Belt HYLABs built their reputation on great reliability and durability, and these proven components have been integrated again on the 228,” said Knight.
Matching main and auxiliary “power-up and power-down” winches come standard equipped with selectable freefall. Main hoist drums are grooved for 26 mm wire rope. Each winche provides up to 43,198 lbs. of single-line pull and features Link-Belt’s proven wet-brake design for superior load control during freefall operation.
When activated, Link-Belt’s Eco Winch allows maximum line speed while hoisting light loads with the engine at idle. It increases fuel efficiency, lowers operating cost, reduces engine speed under load, and reduces emissions.
Hydraulic counterweight removal, upper hand rails, fold-down catwalks, and excellent access are all staples of the HSL Series that are also built into the 228 HSL.
Operator’s Cab
On-board high-resolution winch-view, rear-view, and blind-side swing-view cameras enhance jobsite visibility from in the cab. The functional and comfortable operator’s cab includes a full LED system monitor, AM/FM digital clock radio, and adjustable armchair-mounted controls. The ergonomic design offers the operator greater visibility, more room, and a six-way adjustable seat.
An audio/visual travel alarm system alerts crew members on the ground. The intuitive RCL monitoring system provides all lift information and allows the operator to set swing and other control parameters creating virtual walls with audio, visual alarms and function kickout. High-output air conditioning and heating is standard and makes the 228 HSL a great place to work in any weather.
Attachment
Like many Link-Belt HYLABs, the 228 HSL will offer two styles of boom: tubular boom, up to 235 ft., and angle boom, up to 155 ft. Link-Belt’s open throat boom top features quick-reeve capability and incorporates a fold-down three-sheave-idler assembly.
“The newly designed idler will allow three working lines to run independently up and down the boom, and make for more gradual radius rope travel over the head sheaves. The idler can be easily stored for transport by rotating down and riding inside the boom,” said Knight. A fixed jib, common to the 218 HSL, with lengths of 30 to 75 ft. in 15 ft. sections is available.
Lower
The robust lower carbody is built to withstand all job-site conditions and capacity loadings. Standard features include hydraulically extendable crawler side frames, hydraulic car body jacks, swing-out axle extenders, and centralized grease points.
The Side frames feature completely sealed components, hydraulic track tensioning, and self-cleaning full-contact track shoes. When extended, the tracks provide a 14'6" gauge for a sturdy operating base. Two 13,250 lb. hook-and-pin mounted carbody counterweights fit neatly between the retracted side frames.
Transport
To accommodate varying transport regulations throughout North America, the 228 HSL is equipped with car body jacks and quick disconnects for lower hydraulics for quick and easy installation and removal of side frames when needed. Once on a transport trailer, the 228 HSL has a retracted track width of 11 ft. 11 in. (3.6 m). A 9-piece modular counterweight configuration makes it easy to move the 228 HSL, and depending on geography it can transport with full counterweight in four or five loads.
Standout features of the 228 HSL:
Third drum common to 218 HSL for “plug and play”
30 ft. – 75 ft. fixed jib common to 218 HSL
