![]() The HIAB range offers a wide choice of cranes to suit all vehicle sizes and lifting requirements:ġ2tm HIAB Light Cranes For Small & Medium Vehicles LOLER dictates that, for the purposes of HIAB crane safety, it must clearly show a decal with its Safe Working Load (SWL), which is the maximum load it can lift safely. However, there is no recognised standard for what radius it should be based on and so one manufacturer’s specification may differ from another’s. A crane that can lift 2.5 tonnes at a boom length (radius) of 4 metres is classed as a 10tm crane. That is why the lifting capability of cranes is sometimes expressed in Tonne Metres (tm). To paraphrase it: the longer the reach of the tip of the boom from the centre of gravity, the less weight it is able to lift. Lifting capacity goes back to Archimedes and his Law Of The Lever around 200 BC. Let’s look at the lifting capability of a truck mounted HIAB crane.Ĭonstraints On The Maximum Weight That A HIAB Crane Can Lift ![]() They provide the ability to lift, manipulate and manoeuvre to collect and deliver anything from builder’s merchant supplies to forestry timber and much more with improved safety and in less time.
