Bobcat T3571 Specifications
The Bobcat T3571 telehandler is a mid-capacity
rough-terrain telescopic handler engineered for construction, industrial
materials-handling, and agricultural operations requiring a powerful combination
of lifting performance, reach capability, maneuverability, and reliability. With
a rated lifting capacity of 3,500 kg (7,716 lb) and a maximum lifting height of
approximately 7.1 m (23.3 ft), the T3571 fits the operational needs of
small-to-medium construction sites, warehouse yards, farms, and multi-purpose
material-handling operations.
The telehandler is commonly equipped with either the Perkins 1104C-44T or the
Perkins 1104D-44TA engine, both of which are industrial-grade 4-cylinder diesel
engines known for their durability, strong torque curves, and ability to
maintain consistent hydraulic power under continuous load. The 1104C-44T uses a
mechanically controlled fuel-injection system offering proven long-term
reliability, while the 1104D-44TA features updated fuel and air handling
improvements that yield better emissions performance, smoother operation, and
improved cold-start behavior.
The T3571 offers robust build quality with a reinforced welded steel chassis, a
telescopic boom designed for long-term structural stability, and a full-time
hydrostatic driveline that provides strong traction on uneven or loose ground.
Its 4-wheel drive system, planetary axles, wet-disc brakes, and oscillating rear
axle make it suitable for difficult terrain.
Operators benefit from a comfortable cabin with
good outward visibility, intuitive control layouts, responsive steering,
and straightforward daily maintenance. The machine provides a
well-rounded blend of lift performance, reach capability, durability,
and serviceability.
The Perkins 1104C-44T is a turbocharged 4-cylinder
diesel engine designed for industrial and agricultural machinery. It emphasizes
long service life, consistent torque output, and simple mechanical maintenance.
