Bobcat V623 Specifications
The Bobcat V623 telehandler equipped with the Perkins
1004-40T turbocharged diesel engine is a powerful, mid-capacity telescopic
handler engineered for heavy lifting, extended reach, material placement, and
demanding cyclic operations in construction, agriculture, industrial logistics,
rental fleets, and maintenance facilities.
With a rated lifting capacity of 6,500 lb
(2,948 kg) and a maximum lifting height of approximately 283 in (7.20
m), the V623 provides a strong balance of lifting performance, reach
capability, stability, maneuverability, and operator comfort. Its
combination of hydrostatic drive, permanent four-wheel drive, three
steering modes, and heavy-duty two-section telescopic boom allow the
machine to operate efficiently in confined or open environments.
The Perkins 1004-40T engine provides reliable low-end torque, stable
power delivery across a wide rpm range, and excellent durability in
high-duty cycles. Known for long service life and mechanical simplicity,
the Perkins 1004-40T is widely used in industrial machinery, ensuring
dependable support for daily lifting, loading, scooping, and travel
operations. The V623 telehandler integrates this engine into a robust
drivetrain architecture with planetary final drives, hydrostatic
transmission, and strong hydraulic systems, allowing operators to manage
heavy materials at height with confidence.
Ergonomic cab design, improved visibility, well-organized controls, and
strong structural framing further enhance operator comfort and machine
durability. The V623 uses the Bob-Tach or Power Quick-Tach attachment
interface, enabling compatibility with forks, buckets, bale handlers,
grapples, sweepers, augers, and specialized lifting attachments. This
level of versatility makes the V623 a valuable multipurpose machine for
any high-demand worksite. When maintained according to recommended
intervals, the machine provides reliable, safe, and efficient lifting
and material-handling performance with reduced downtime.
The Perkins 1004-40T is a 4-cylinder turbocharged
diesel engine designed for industrial and construction applications where
sustained durability, strong torque at low rpm, and dependable performance are
essential. Its mechanical fuel system and simplified design contribute to
long-term reliability and low maintenance cost.
