Link-Belt at it again with its new 238 HSL
We listen To make the 238 HSL the perfect general contractor machine, customer input drove much of the new design. The crane comes standard with folding upper guardrails and full-length right and left catwalks with grab handles. A rear-view, high-resolution camera and a color screen in the cab helps the operator stay up-to-date on jobsite conditions while an outside travel alarm helps keep the ground crew informed. The new HSL monitoring system allows the operator to set swing and other control parameters creating virtual walls with audio and visual alarms. Heart and soul The heart of the 238 HSL is the 286-horse power (213.3-Kw) Isuzu 6HK1 engine with interim Tier IV DPF. Link-Belt tested this new after-treatment system to help ensure critical uptime while producing reliable, clean-burning power. The soul of the 238 is bolted to the whisper quite Isuzu. The high-performance tandem main piston pump and gear package provides total horsepower control by maximizing available power for the highest flow or speed, as needed, while 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 feed back to the operator. Piston motors drive the swing and travel systems, front and rear winches and the boom hoist. Main winches come standard with power up, power down, with automatic brakes. Wet-style brakes for freefall on both drums are also standard to meet the demands for cranes in this class. Great feedback is also present in the freefall foot brakes, greatly reducing stress and fatigue on the operator. The 238 HSL comes with a new foot-operated, all-hydraulic swing brake. This new brake system (void of mechanical or friction components) allows the operator greater control under a wide range of conditions. Moving on up Because it's so easy to transport, the 238 HSL makes money every time you move it. The modular counterweight removal system lowers the counterweights to the ground from the remote control station, much like Link-Belt's 218 HSL. 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 20,000-pound (9 071.8-kg) "A" counterweight and six 15,000-pound (6 804-kg) biscuit counterweights. Main counterweight release and engage pins simplify the assembly/disassembly process. For even quicker mobility, the 35,000-pound (15 875.7-kg) side frames attach via hook and pin. The main load with base and self-erection equipment weighs less than 87,000 pounds (39 462.5 kg). Where it counts The 238's main boom length is 50–260 feet (79.2–15.2 m)¬¬. A fixed jib ranges from 30–80 feet (9.1–24.4 m) and maximum tip height is 310 feet (94.5 m) with a 230- plus 80-foot (70- plus 24.4-m) combination. A luffer will also be available. While there's an all new top section and base section, extensions are common with 238 HYLAB 5 sections. All these add up to serious capacities—main boom, jib and luffer. Comfort and convenience The 238 HSL's cab is highly functional and comfortable. In addition to the full complement of backlit gauges and adjustable armchair-mounted controls, the ergonomic design offers the operator several advantages: greater visibility; more room; adjustable boom, swing, and load hoist controls; six-way adjustable seat; and an AM/FM digital clock radio. And for those hot days, high-output air conditioning is standard. As a result, the 238 is a pleasant place to work.
