In 2005, JCB, Pooler, Ga., introduced the Model 550-170 Loadall as a replacement for its 5508. The 550-170 is the largest of JCB's 14 Loadall telescopic tool carriers.
The low boom configuration increases strength, which translates to an 11,000-pound on-grade breakout force. The unit's boom works with twin extension cylinders, which have been extensively tested to ensure durability.
Incorporating a unique driveline layout, the 100-hp JCB Dieselmax engine is mounted transversely on the right side of the chassis and located under a cylinder-assisted, swing-up engine compartment. A JCB four-speed power-shift transmission incorporates the torque converter and gearbox in one mounted unit.
The unit also incorporates JCB-brand epicyclic hub reduction drive/steer axles with Max-Trac torque proportioning differentials. Self-adjusting, multi-disc service brakes operate on the front and rear axle. The parking brake is a hand-operated disc brake on the output of the gearbox. Operators use a single multifunction joystick to control the machine, and a tri-control is available as an option. The rear window can open and close, allowing operators to adjust the environment.
JCB also offers the Assetcare machinery protection plan on the 550-170. This program protects equipment owners against unexpected failure for up to five years.
