The SPT499 Spider Crane with a hydraulic fly jib is a versatile and powerful crane, well-suited for a range of industries including construction and specialised lifting tasks. The inclusion of a hydraulic fly jib significantly enhances its capabilities. Its standout feature remains its maximum loading capacity, which may differ slightly from the standard model, particularly when the fly jib is extended. With the hydraulic jib, the working radius and lifting heights could be extended further, offering greater flexibility and reach.

In terms of technical specifications, the SPT499 with the hydraulic jib is likely to maintain its 5-section boom with hexagonal box construction. The extension length of the boom, as well as the winch specifications such as hook speed and rope type, might slightly vary with the addition of the fly jib. Similarly, the crane’s continuous slew angle and walking speed would be designed to accommodate the extra weight and balance of the hydraulic jib, ensuring safe and efficient operation.

The diesel engine and optional electric motor should provide sufficient power for both the crane and the hydraulic jib, though the overall weight of the crane is likely to increase slightly due to the additional equipment. This enhanced model is designed for increased manoeuvrability and versatility, capable of operating in various operational settings, including challenging terrains and confined spaces, just like the standard SPT499 model.
