JCB 505-20TC Specifications
The JCB 505-20TC Loadall Tool Carrier is a compact,
high-capability telescopic handler specifically engineered for confined
construction sites, industrial yards, landscaping operations, and agricultural
facilities where maneuverability, low overall height, and precise load placement
are critical.
As part of JCB’s Tool Carrier (TC) range, the
505-20TC combines the versatility of a skid-steer-style attachment
interface with the reach advantages of a telescopic boom, allowing it to
perform lifting, placing, loading, and handling tasks typically beyond
the scope of compact loaders.
With a maximum rated lift capacity of 5,500 lb (2,500 kg), a maximum
lift height of 20 ft (6.0 m), and a forward reach of 11 ft 6 in (3.5 m),
the 505-20TC delivers strong performance relative to its compact
footprint. Its low-profile chassis, hydrostatic transmission, permanent
four-wheel drive, and three-mode steering system allow confident
operation on uneven terrain and within restricted spaces.
Designed to meet ANSI B56.6 stability
requirements, the 505-20TC emphasizes operator safety, predictable
handling characteristics, and long-term durability while remaining easy
to service and economical to operate.
The JCB 505-20TC is powered by a modern JCB Diesel by
Kohler turbocharged diesel engine designed to meet current emissions regulations
while delivering high torque at low engine speeds.
