Pick and carry cranes are known for their excellent performance in confined spaces – and sometimes a lifting project comes along that tests this to the limit.
That was certainly the case when Hird was commissioned to lift a 2.5 tonne transformer into position down a fully-enclosed alley in the centre of Morpeth, Northumberland.
Hird Managing Director Phil Hird said: “Sometimes the term ‘inches to spare’ is misused, but not on this occasion. It was perhaps more like millimetres to spare.”
Perfect mini crane for tight squeeze
The only access to the site where the transformer needed to be placed was through an archway and down an alley which, many years before, probably led to stables.
The Hird lifting team selected a Valla 90E mini crane to carry out the task. It had the right lifting capacity and was just compact enough to be driven with extreme care to where the transformer needed to be placed.
“Our team said it was one of the tightest squeezes they’d ever seen a crane manage,” said Phil Hird. “We’d done our measurements with a great deal of care, and the Valla 90E performed very well.”
Silent crane keeps neighbours happy
The pick and carry crane has a maximum safe working load of 9 tonnes. It is just 1735mm wide and 2290mm high which gave just the smallest margin for error in guiding the machine into position.
As an electric crane, the Valla 90E is almost silent, which was also a significant benefit, given that the lift had to be done in the middle of the night, and it was important not to disturb local residents.
The team made use of the mini crane’s hydraulic luffing jib to control and place the load with precision, another important attribute when working in confined spaces.
A pick and carry crane for all lifting projects
Hird has a wide range of Valla pick and carry cranes for hire or to use for contact lifts and machinery moving.
The smallest is the Valla 20E, which has a maximum safe working load of 2 tonnes, while the largest is the Valla 250E which can lift 25 tonnes, but also operates just as effectively in confined spaces.
