Bobcat V638 Specifications
The Bobcat V638 telehandler is a mid-capacity,
rough-terrain material-handling machine engineered for demanding applications
requiring a combination of lifting strength, long forward reach, compact
maneuverability, and versatile hydraulic performance. Designed to replace
multiple machines on a jobsite - such as industrial forklifts, compact loaders,
and cranes - the V638 integrates a three-stage telescopic boom, four-wheel
drive, three steering modes, and a highly durable hydrostatic driveline.
Its rated lift capacity of 6,700 lb (3,039 kg)
and maximum lift height of 38 ft (11 m) position it as a powerful
solution for construction, agriculture, industrial yards, landscape
material distribution, mining support, equipment rental fleets, and
maintenance operations. The machine is powered by a 100-hp industrial
diesel engine, commonly the Perkins 1104C-44T, known for strong low-end
torque, high durability, and simple serviceability.
Combined with a hydrostatic transmission,
planetary reduction axles, high-flow auxiliary hydraulics, and excellent
visibility through a loader-style cab layout, the V638 provides precise
control, strong breakout forces, and predictable load-handling behavior
even under uneven terrain or extended boom configurations. Properly
maintained, the V638 delivers long-term operational stability, reduced
downtime, and strong performance in lifting, loading, and
attachment-based applications.
