JCB 506-23TC Specifications
The JCB 506-23TC Loadall Tool Carrier is a compact yet
highly capable telescopic handler designed to combine the versatility of a
skid-steer loader with the reach and lift advantages of a telescopic boom.
Developed for construction sites, industrial yards, agricultural operations, and
rental fleets, the 506-23TC excels in applications where frequent attachment
changes, precise load placement, and maneuverability in confined spaces are
essential.
With a rated lift capacity of 6,000 lb (2,722 kg), a maximum lift height of 23
ft (7.0 m), and a maximum forward reach of approximately 12 ft 2 in (3.7 m), the
506-23TC offers substantially more vertical and horizontal reach than compact
loaders while maintaining a relatively low overall height and short wheelbase.
The machine features a hydrostatic transmission
for smooth, infinitely variable travel control, permanent four-wheel
drive, and a robust high-tensile steel boom. Its JCB Tool Carrier (TC)
interface allows the use of skid-steer compatible attachments,
significantly expanding the machine’s functional range.
Designed to comply with ANSI/ITSDF B56.6 stability standards, the
506-23TC emphasizes predictable handling, operator safety, and
durability. The combination of modern JCB EcoMAX engine technology,
advanced hydraulics, and straightforward service access makes it a
reliable and economical choice for operators requiring a compact yet
powerful material-handling solution.
The JCB 506-23TC is powered by the JCB EcoMAX
four-cylinder turbocharged diesel engine. This engine is engineered for
industrial duty cycles, delivering high torque at low engine speeds, low fuel
consumption, and compliance with modern emissions regulations.
