Link-Belt HTC-1055 Load Chart PDF + Specifications

The Link-Belt HTC-1055 hydraulic truck crane is designed to meet the needs of mid-capacity lifting operations while offering highway-capable mobility. Its main lifting feature is a four-section power boom extending from 38’0” to 120’0” (11.58 m to 36.73 m), incorporating a base section, two power telescoping sections, and a manually pinned fourth section. The boom uses diamond-shaped impression plates and 100,000 psi (689.5 MPa) steel angle chords for enhanced stiffness and strength. Boom extension is supported by wear shoes both vertically and horizontally, and the fourth section is extended manually through a simple cylinder locking system.

The standard boom head comes equipped with five 14-1/4″ (0.36 m) diameter sheaves accommodating up to 10 parts of 3/4″ (19 mm) wire rope. An optional auxiliary lifting sheave allows for use with one or two parts of line off the optional front winch. Boom elevation ranges from -3° to 78°, controlled by two FMC-designed double-acting hydraulic cylinders with integrated holding valves.

For additional lifting height and offset, the HTC-1055 can be configured with a 34’6” (10.52 m) stowable one-piece lattice fly and an optional 30’ (9.14 m) A-frame jib. The jib and fly can be offset at 5°, 17.5°, or 30° angles, providing versatile lifting configurations for elevated or hard-to-reach loads.

The crane is mounted on an FMC 8×4 carrier chassis, 10’1.5″ (3.09 m) wide with a 230-1/2″ (5.85 m) wheelbase. The frame is fabricated from high-strength alloy steel with an integral box-type structure and outrigger boxes for enhanced stability. Hydraulic outriggers extend to 22’4″ (6.81 m) centerline-to-centerline and retract within a 10’1.5″ (3.09 m) travel width. The system includes single-beam outriggers with vertical jack cylinders, and the front bumper outrigger is standard with a 20″ (0.51 m) float for 360° lifting capability.

Engine options include the GM 6-71N, a 6-cylinder 2-stroke diesel producing 238 hp at 2,300 rpm and 635 ft-lbs of torque, or the Cummins NTCC-230, a 6-cylinder 4-stroke diesel rated at 230 hp at 2,100 rpm and 650 ft-lbs of torque. Both engines use a 92-gallon (348.22 L) fuel tank and are coupled to a Fuller Roadranger RTO-6613 transmission with 13 forward and 3 reverse gears. The crane can reach travel speeds of up to 55.7 mph (89.6 km/h) with the GM engine and 50.9 mph (81.9 km/h) with the Cummins, offering gradeability up to 35%.

The load hoist system includes the standard Model 2M17 rear winch with two-speed motor, automatic brake, and bi-directional hydraulic operation. Optional configurations include a second front winch or a Model 3M winch for true gravity free-fall capability. Each drum uses 17” (0.43 m) diameter root sheaves with a maximum permissible line pull of 14,430 lbs (6,545 kg) and a line speed up to 548 fpm (167.03 m/min).

The hydraulic system is powered by a four-section gear-type main pump and controlled via six separate control valves. System pressure reaches up to 2,900 psi (200.0 Bars). The 140-gallon (530.0 L) reservoir includes a fine filtration system and hydraulic oil cooler.

Operator comfort and control are prioritized with a fully enclosed, environmentally sealed cab mounted on the upperstructure. It features tinted safety glass, sliding and swing-up windows, and a 6-way adjustable seat. Controls are provided for all crane functions, including swing, boom telescope, boom hoist, and winches, with foot pedal actuation for the swing brake. The cab includes dash-mounted gauges for hydraulic temperature, fuel, oil pressure, and water temperature, alongside standard indicators and alarms.

In all, the Link-Belt HTC-1055 offers a dependable solution for lifting operations that require a balance of mobility, strength, and operator ease. It is a well-suited crane for steel erection, precast work, and utility infrastructure where 55-ton lifting capacity and rapid deployment are critical.
