LEXINGTON, Ky. (March 2003) — Link-Belt Construction Equipment Co. announces the new 238 HYLAB 5, 150-ton (136 mt) lattice boom crawler crane. The 238 HYLAB 5 crane features increased capacities with longer conventional boom, completely new, roomier cab, a new SML-10 load moment indicator, slab-type counterweights, more engine horsepower and a remote hydraulic oil cooler.
Link-Belt’s HYLAB (HYdraulic LAttice Boom) Series of lattice boom cranes with hydraulic controls was first introduced in 1987 and today has more that 2000 units operating worldwide. Today’s new 238 HYLAB 5 crane enjoys a legacy of customer satisfaction with bulletproof reliability, low operating costs and productivity that continues to lead the industry in bringing to market enhanced features that have set the standard for crawler crane performance.
“We’ve made a great crane even better,” says Pat Collins, senior product manager, lattice boom cranes. “The features we’ve added make the 238 H5 unbeatable in its class.”
Strongest lift chart in class
With a newly designed lower and additional 51,000 lbs. more counterweight, the 238 HYLAB 5 in some areas of the chart out picks its predecessor by 10 tons.
The 238 H5 features 140,000 lbs. (65 503 kg) of total counterweight in a nine-piece design. It consists of one, 14,000 lbs. (6 530 kg) base counterweight, six, 13,000 lbs. (5 897 kg) wing counterweights and two, 24,000 lbs. (10 886 kg) side frame counterweights. All of the upper counterweights quickly and easily mount on the upper with the newly designed hydraulic lift system. The side frame counterweights are self-installed, also using the boom base and 10 ft. (3.05 m) self-assembly section.
The machine’s tread members measuring 25 ft. (7.52 m) long with a 19 ft. 2 in. (5.84 m) overall width are all-welded, precision-machined steel frames are mounted on the lower frame using the boom base and 10 ft. (3.05 m) self-assembly section. The tread members feature 44” (1.12 m) self-cleaning track shoes, sealed track rollers, idler and drive planetaries, hydraulic track tension and compact hydrostatic drives for maintenance free operation. The crane is equipped with hydraulic jacks for easy track removal and loading.
Standard left, right and front catwalks easily remove and store for transport. The complete machine, with maximum boom and jib, loads out in seven loads.
Attachment options - not only stronger, but also longer
The 238 HYLAB 5 is equipped with 260 ft. (79.25 m) of new conventional tube boom, 10 ft. (6.10 m) more than the nearest competitor. Bar pendants are new and attach to the boom extension for easy storage.
A fan-post style luffing attachment is available with a 347 ft. (105.8 m) maximum tip height. The maximum working load and radius is 3,100 lbs (1 406 kg) at 233 ft. (71.02 m). The maximum luffing boom, luffing jib and fixed fix combination is 165 + 150 + 30 ft. (50.29 + 45.72 + 9.14 m).
In addition to its outstanding lift crane capabilities, the boom top sections have universal connecting lugs for auxiliary sheaves and a pile-driving adapter. To make the 238 HYLAB 5 even more versatile and productive, “blocked-over-end” capacities are available, and the rated capacity limiter is equipped with load sensing cells in the boom hoist dead-end.
The front drum maximum hoist pull is 41,750 lbs. (18 939 kg) and line speed is 412 ft/min. (125.6 m/min). The rear drum maximum hoist pull is 25,762 lbs. (11 686 kg) and line speed is 667 ft/min. (203.3 m/min). The large, grooved hoist drums are easily accessible for routine maintenance. Matching rear to front drum performance is an available option.
An optional third drum is available with 20,555 lbs. (9 324 kg) maximum line pull and 365 ft/min. (111.3 m/min) of maximum line speed. The clamshell / dragline rating is 22,700 lbs. (10 297 kg) with 100 ft. (30.5 m) of tubular boom. A hydraulic, fan-driven, remote mounted hydraulic oil cooler with thermostatic control to ensure cool running hydraulic oil and components in duty cycle applications.
New HYLAB cab with user-friendly features
The 238 HYLAB 5 cab features a full complement of “operator-friendly” gauges and controls, such as backlit gauges, adjustable armrest-mounted, single-axis controls, low-effort hydraulic pedals with minimal pedal range of motion. Another “creature-comfort” feature is the environmental control unit with standard 18,600 BTU cab air conditioning and 19,000 BTU heater. The ergonomic design offers the operator several advantages, such as greater visibility; more room, easy to read and intelligently located controls and gauges, adjustable boom and load hoist controls and an six-way adjustable seat. Most importantly, the new cab is set up to be highly functional and very comfortable.
