SCX Special Projects designed, manufactured and installed a bespoke Transporter Bridge capable of lifting, rotating and distributing jet engines around the maintenance bays at Rolls Royce’s Engine Test Facility in Derby.
Rolls Royce’s original Transporter Bridge, designed to traverse the depth of the building between build stations and maintenance bays, had no rotation capability. Prior to SCX Special Projects’ installation, Rolls Royce had to lower the engines down onto the back of flat-bed trucks in-between processes, so that they could be manoeuvred into the correct orientation before being raised back up and docked into the build stations.
SCX Special Projects were appointed to develop an enhanced handling solution, which would encompass all the benefits of the existing system, whilst adding a rotation and alignment function for use between bays.

Positioned 15m high, the bespoke transporter bridge supports and rotates two main hoist and lifting
attachments (or the ‘Green Brick’ and ‘Yellow Brick’) which couple with the docking frames that support the jet
engines. To account for the weight imbalance of the engines, the system is built to support cantilevered loads
of 44 tonnes at the front and 14 tonnes at the back.
The rolled-beam construction central turntable rotates the independent Bricks on support rails then travels the depth
of the building to accurately dock with multiple maintenance bays, where the Bricks traverse on and off
the bridge into each bay.
To allow rotation in the available space, the Brick support rails are shorter than the span between the bays. To then enable the support rails to mate with the bay rails, they are connected to the circular turntable by six bearing assemblies which provide horizontal motion across the transporter bridge, powered by a screw-jack.
The cantilevered load as the Bricks transfer onto the bay rails from the
transporter bridge, is supported and controlled by hydraulic cylinders
which clamp the rail junctions together prior to the transfer. This
process is fully automated, making a complicated transition very simple
for the operator.
