Kobelco RK450 (Panther 450)

The Kobelco RK450 is a highly capable 45-ton class rough terrain crane, engineered for enhanced reach, quiet operation, and jobsite versatility. It features a five-section telescopic boom with a maximum reach of 38.9 m, extendable by a 1-stage (9 m) or 2-stage (15 m) jib to a total boom and jib combination of 53.9 m. This allows the crane to achieve a lifting height of up to 54.3 m, placing it among the top in its class for height capabilities. With a working radius of 22 m, it is designed for operations that demand both vertical reach and horizontal outreach.

The crane is designed with user-friendly transportability, ideal for long-distance travel. The vehicle incorporates a high-efficiency, low-noise engine coupled with a power steering system that allows smooth maneuvering in tight jobsite conditions. Noise emission levels are kept to a minimum, with the RK450 producing only 61 dB (A) at a 30 m distance — especially valuable in urban or night-time operations.

An advanced boom control system facilitates synchronized telescoping, and new systems such as the automatic soft-down control and foot brake gear assist smooth crane movements and operator comfort. Options such as the dynamic damper (to reduce vibration during high-speed travel), rear-view drum monitoring TV, and operational zone restriction device offer improved safety and convenience.

Additional features include a voice alert system for operation status, an FM/AM radio for in-cab comfort, and a compact boom overhang that makes it easier to approach confined work zones. With these enhancements, the RK450 combines powerful lifting performance with advanced technology for safety, transportability, and operator ease — all in a machine built to handle urban and industrial lifting needs.
