Kobelco RK700-2 (Panther 700)

The Kobelco RK700-2 (PANTHER 700) is a high-performance 70-ton rough terrain crane, officially launched in March 2015 by Kobelco Cranes in Shinagawa-ku, Tokyo. This model was developed specifically for the Japanese market and places significant emphasis on operational safety, compactness, and eco-friendliness. Kobelco, a leader in crawler crane technology, continues to refine its wheeled crane offerings with the RK700-2 — a machine engineered to meet modern job site challenges in confined urban spaces and regulated environments.

The crane features a boom length ranging from 9.8 to 44.0 metres, made possible by a lightweight round boom design that ensures both high rigidity and reduced overall weight. To extend reach further, the RK700-2 is equipped with an optional 3-section full automatic jib, offering lengths from 8.4 to 17.7 metres, and capable of reaching a maximum lifting height of 63.0 metres with the jib installed. The full boom alone offers up to 45.2 metres lifting height, and the working radii are equally impressive, with 34.0 metres (boom) and 45.5 metres (jib over front).

One of the standout innovations in the RK700-2 is the under-slung installation method of the jib. This design dramatically improves job site safety, as it eliminates the need for working at height during jib assembly or stowage. The result is faster setup, safer operation, and greater ease of use. The design also facilitates space-saving operation in congested areas and improves overall efficiency.

In terms of mobility, the RK700-2 is remarkably compact for its class, with a total width of only 2.78 metres and a boom overhang of just 6.435 metres, adhering to Japan’s stringent Ministry of Land, Infrastructure, and Transport guidelines. Despite this compact footprint, the crane maintains high stability and lifting capacity. It is also equipped with advanced control systems, including a multi-display interface and a wide range of safety devices, ensuring precise operation and operator confidence.

Powering the RK700-2 is a Cummins QSL9-4A diesel engine, delivering 276 kW at 1,900 rpm, compliant with low emissions, low noise, and low fuel consumption standards, aligning with Japan’s environmental expectations.

Kobelco initially set a sales target of 12 units per year, indicating a strategic approach to meet domestic demand in highly regulated urban lifting environments.

With its combination of strong lifting performance, compact dimensions, advanced safety features, and eco-conscious engineering, the RK700-2 reaffirms Kobelco’s position not only in crawler cranes but also as a significant player in the rough terrain crane market.
