Allowed comGGR’s 1t mini crane has helped to build a new glass entrance at Caernarfon Castle recently.

Caernarfon Castle, King Edward I’s intimidating stone fortress is considered one of the most impressive of Wales’s castles, a claim backed up by its World Heritage status. The castle attracts 1000’s of visitors each year and as a result there is a need for increased visitor space and improved facilities. The great honour of World Heritage status comes with great responsibility; making any structural changes to the castle is a definite no-no, this problem is being solved using glass.

A UNIC URW-095 was hired to build a new glass entrance way to the castle. Boasting nearly one tonne of lifting power and an unrivalled lifting height of up to 8.8m, the Unic 095 is one of the most popular mini cranes in the industry. The advanced safety system of the UNIC 095 mini crane includes turnover protection with stability, warning lamps and alarm to reduce the risk of the crane tipping over. Customer safety is always at the top of our priorities, not least when working with an ancient and protected structure!

The mini crane teamed up with two glass vacuum lifters to install the glass units that varied in size with the largest piece measuring 4.3m x 1.6m. The Quadra-Tilt MRTA6, with its 500kg lifting capacity, was able to handle the heavier glass with ease.  This dual circuit vacuum lifter features a unique geometric tilt mechanism which maintains the load position automatically when tilting between horizontal and vertical positions, enabling precise operation. The versatile P11104 Connect-4 vacuum lifter was also on hand to help install the various glass panels; this popular glass vacuum lifter comes with on-board power from a rechargeable battery, making it fuss free to use.

The site of this great castle wasn’t chosen by accident. It had previously been the location of a Norman motte and bailey castle and before that a Roman fort stood nearby. The lure of water and easy access to the sea made the banks of the River Seiont an ideal spot for Edward’s monster in masonry. Edward’s son, the first English Prince of Wales was born in the castle and in 1969 the investiture of the current Prince of Wales, HRH Prince Charles took place here. Very regal indeed!

This is not the first time that one of our mini cranes has spruced up a royal residence; take a look at a UNIC URW-506 mini spider crane working at Astley Castle.
