Tower Bridge, UK
Movable bridges are a specialist area of engineering. Our
experience enables us to offer a complete range of services from
feasibility studies, detail design and specification to
construction supervision and inspection to commissioning and
project management.
We have experience of many different drive systems to cater for the
various types of movable bridges including swing, lifting and
bascule types. Examples of drive systems which we have designed and
commissioned include roller chain drives for swing bridges, winch
drives for lifting bridges and hydraulic power cylinder drives for
bascule bridges. However, the choice of the most suitable drive
system and power source is considered for each particular
application to achieve the required operational performance and
ensure long term reliability and ease of maintenance.
Notable movable bridge projects include:
- Thames Crossing at Blackwall, UK – feasibility study for
a road crossing to provide
Mutford Bridge, UK150m navigation opening
- Tower Bridge, UK – detailed
inspection and strength assessment including repair and replacement
of sections of carriageway deck
