JCB 527-55 Specifications
The JCB 527-55 Loadall telehandler is a compact,
high-capacity telescopic handler engineered for construction, agricultural,
industrial, and rental applications that require strong lifting performance
within confined working areas. As part of JCB’s Compact Loadall range, the
527-55 combines increased lift capacity and reach compared to smaller models
while maintaining a relatively low overall height and excellent maneuverability.
The machine offers a rated operating capacity
of 2,721 kg (6,000 lb), a maximum lift height of 5.6 m (18 ft 4 in), and
a maximum forward reach of 3.3 m (10 ft 10 in), making it well suited
for pallet handling, material placement, masonry work, and general site
logistics.
The 527-55 is built around a rigid compact chassis with permanent
four-wheel drive and three selectable steering modes, allowing efficient
operation in tight spaces and on uneven terrain. Power is supplied by a
turbocharged diesel engine delivering strong low-speed torque, while a
hydrostatic transmission provides smooth, infinitely variable travel
speed control.
A responsive hydraulic system ensures precise
boom movement and attachment control. Overall, the JCB 527-55 is
designed to deliver durability, productivity, and ease of service in
demanding daily operations.
The JCB 527-55 is powered by a turbocharged
four-cylinder diesel engine developed for off-highway industrial applications.
