Spierings AT – the collective page of the self-erecting mobile cranes on truck chassis from Oss in the Netherlands: six-cylinder engines, gross weights of 34,900 to 59,900 kg, lengths up to 13,020 mm
This collective page gathers the AT range from the Dutch crane maker Spierings, headquartered in Oss. Spierings builds self-erecting mobile cranes that drive to the construction site on their own truck chassis and erect themselves there without additional auxiliary equipment, a design developed especially for tight inner-city building sites where a classic tower crane with a separate assist crane cannot be set up. The AT 3 to AT 5 models in the register differ in crane class and therefore in reach and lifting capacity.

The register lists 5 versions from six-cylinder engines throughout, with unladen weights from 34,900 to 59,900 kg and gross weights from 35,000 to 60,000 kg; lengths range from 12,310 to 13,020 mm, widths from 2,600 to 2,620 mm.
With its self-erecting cranes, Spierings occupies a niche between classic mobile cranes and stationary tower cranes, and is used chiefly in residential construction and inner-city building projects in the Netherlands, Germany, Britain and Scandinavia, where the footprint and access are limited.
On a used Spierings AT, the condition of the hoist, wire ropes and boom telescope, the function of the outriggers and the hydraulic erection mechanism, rust on the chassis frame, and the crane's operating-hours history all count; parts and service are provided by Spierings itself.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Ask about parts availability for this build year — the running costs hang on it.
