Cat TH330B Specifications
The Caterpillar TH330B telehandler is a highly
versatile, mid-capacity lifting machine engineered for demanding construction,
industrial, and material-handling operations. With a rated load capacity of 3200
kg (7,000 lb), a maximum lift height of 7.2 meters (24 ft), and a robust
three-section boom, it delivers strong loading and placement performance while
maintaining excellent stability.
The TH330B is part of the Caterpillar B-Series
telescopic handler family, recognized for rugged build quality,
electronic engine control, durable drive axles, and highly responsive
hydraulic systems. Thanks to its combination of a powerful Cat 3054E
diesel engine, four-speed powersyncro transmission, planetary axles, and
full-time 4WD, the TH330B is built to operate reliably in tough, uneven,
and high-duty environments.
With three steering modes, ergonomic controls,
integrated electronic diagnostics, and compatibility with a wide range
of attachments, the TH330B provides a balance of versatility,
productivity, and economical ownership. Caterpillar’s extended service
intervals reduce downtime and ensure low-cost operation over thousands
of hours of use.
