HMS Bulwark and HMS Albion are two 18,500t landing platform dock ships that form part of the Royal Navy’s amphibious assault force. They are used to transport, deploy and recover troops, equipment, vehicles and cargo.

Houlder said the capability to safely lift, manoeuvre and quickly load equipment throughout the ships’ internal vehicle decks is essential for their operational success.

Houlder and Street CraneXpress will supply electric travelling monorail hoists with twin ratings of 6t SWL for general loads and 4.5t SWL for handling ordnance at sea.

The hoisting systems will be compliant with Joint Service Publication (JSP) 467 for Power Driven Lifting Appliances used for Handling Conventional and Nuclear Armaments.

Houlder and Street CraneXpress have already installed gantry cranes on HMS Bulwark and HMS Albion, which are also compliant with JSP 467.

Rod Pudduck, Houlder’s defence director, said: “Houlder is delighted to have the chance once again to utilise its knowledge and experience of ammunition-rated lifting equipment.

“Our team is confident in its ability to deliver hoists that integrate with existing ship systems and completely satisfy reliability and safety requirements.”
