GGR Group assisted a client with the installation of a large mezzanine in a packaging warehouse in the UK. As a specialist lifting solution provider, GGR Group had the necessary technical experience and innovative lifting product range to help tackle the intricacies of this unique lifting challenge.

After completing a site survey, risk assessment, and lift plan, the extremely tight setup area, lifting location, permanent structures and the close proximity of the steel beams, meant that this project could prove to be challenging, but of course, GGR Group were more than happy to step up to the challenge.

The client first needed a crane that could install the steelwork for the mezzanine, with the longest piece 9.9m long and 301kg. GGR Group selected the UNIC URW-706 Mini Spider Crane for this task because of its high lifting capacity and compact size. To install the uprights and cross beams of the mezzanine GGR brought in the Cube Crane. This UNIC crane has a three section derricking boom allowing it to gain access to some of the most restricted and confined lifting projects.

The Cube Crane’s multi-positional outriggers allow it to work around obstacles on site with ease. Also designed with access in mind this crane is just 1500mm wide when its outriggers are tucked away allowing it to fit through standard double doorways and corridors.

After the steelwork was lifted by the 706 GGR tracked the Cube Crane to the lift area on plywood sheets. A DPF exhaust filter was also fitted to both cranes which reduces the production of soot particles by up to 99.9%+ keeping the air quality in confined spaces safe. With a max radius of 6m and a needed hook height of 17m working around the various beams was particularly challenging due to the risk of becoming jib bound within the small space between each beam.

GGR’s team strategically placed each steel beam from top to bottom in a way that would prevent the crane from becoming jib bound. Benefiting from the Cube Crane’s three section derricking boom it was able to be set at 85°, 90° and 95° angles allowing the operator to manipulate the load between the most awkward spaces. The radio remote control with Bi-axis joysticks and feedback display also meant that the operator could move with the load for maximum visibility during operation.
