Link-Belt Debuts All New 248 HSL
Link-Belt Construction Equipment debuted the all-new 181 t 248 HSL at CraneFest ’12, September 24 - 28, in Lexington, Kentucky. The 248 HSL is the next generation of the highly successful 248 HYLAB 5 series started over twenty years ago.
The 248 HSL joins the 238 HSL and the newly upgraded 298 HSL as the strongest trio of cranes in the 130-225 t market today. Perfect for the general contractor, the 248 will prove its value in steel erection, bridge work, pile driving and more. It is loaded with all the features and the latest technology to satisfy everyone from the owner to the purchasing agent, and especially the operator.
Like the 238 HSL, customer input drove much of the new design for the 248 HSL. The crane comes standard with folding upper guardrails and full-length right and left catwalks with grab handles. The crane operator will be assisted by an on-board high-resolution back up camera that will help monitor jobsite conditions. An outside audio/visual travel alarm system informs crew members on the ground. The HSL monitoring system provides the operator all critical lift information, is extremely intuitive and allows the operator to set swing and other control parameters creating virtual walls with audio and visual alarms.
Greater fuel efficiency is offered with the new ECO system, resulting in lowered operating cost, less engine RPM under load, and fewer emissions. When activated by the operator, ECO allows maximum line speed with lighter loads while the engine remains under 1,000 rpm. Also, standard equipped as part of this system, the operator-selectable auto-engine shutdown will turn the engine off after extended periods of inactivity, so long as critical operating criteria are met.
The heart of the 248 HSL is the 282-hp Isuzu 6HK1 Tier 4i engine, Link-Belt tested to ensure critical uptime while producing reliable, clean-burning power. The high-performance tandem main piston pump and gear pump package provide total horsepower control by maximizing available power for high flow/speed, as needed, with the highest level of fuel efficiency. The proven Link-Belt hydraulic, pilot operated control system directs and regulates flow to deliver millimeters when needed – every time and with great feel in the levers providing valuable feedback to the operator.
Piston motors drive the swing and travel systems, front/rear winches and the boom hoist. The matching performance 26 mm main winch grooved drums come standard with power up/power down with automatic brakes.
Like its predecessor, the 248HSL has a strong, heavy duty lower with two carbody counterweights to provide a great lifting base and long life with all sealed rollers, idlers, and drive components, along with full contact 111.76 cm shoes, and a 257 cm clearance in its working configuration. Car body jacks come standard with a remote control for fast, easy assembly with increased lowboy clearance both in width and height.
Because it’s so easy to transport, the 248 HSL makes money every time it transports. The modular upper counterweight removal system lowers the counterweights to the ground from the remote control station, much like Link-Belt’s 218 & 238 HSL style. The hydraulic cylinders detach in one piece with the base counterweight to reduce the weight of the main transport load. The upper counterweights consist of a 9,072 kg "A" counterweight and six 6,804 kg biscuit counterweights. Main counterweight release and engage pins simplify the assembly/disassembly process. For even quicker mobility, the 15,875 kg side frames attach via hook and pin. The main load with base and self-erection equipment weighs less than 39,462 kg. Two 8,005 kg carbody weights help provide a strong lift chart in a compact package.
The 248 HSL has a main boom length of 16.8 - 86.9 m and incorporates lifting sheaves in the boom base section for fast assembly and disassembly. A fixed jib ranges from 9.1- 30.5 m for a maximum tip height of 105.7 m.
