The stowed crane uses all of the space in its 3.1 x 0.79 x 1.9 metre package

The 3.2 tonne maximum capacity is available at a radius of up to 2.2 metres and a lift height of around five metres. The key difference on this crane, which earns it the Pop Up moniker, is the rising boom pivot point which enables the entire length of the chassis to be used for base boom stowage, the riser then elevates, almost vertically, raising the boom pivot point to a height of more than two metres, while moving it forward towards the centre of the chassis.

Jib extended

The crane’s overall width when stowed is 790mm, extending to 1.1 metres for extra stability while travelling. The overall length is 3.13 metres, while being just under two metres high. Total weight is 3.67 tonnes.

Power comes from a 159ah lithium ion battery pack, while the crane can also operate while plugged into a 230 volt mains outlet. Radio remote controls are standard, as is a full load moment indicator with colour high resolution screen.
