Case Study
Electrical Houses, DSL Cages & Control Cabs
for Ladle Furnace Cranes
Process Details: `Electrical Houses, DSL Cages & Control Cabs' for three `Ladle Furnace Cranes' currently in
service at the `Stainless Melting & Continuous Casting' facility operated by the UK based `Long Products
Division' of the worlds leading stainless steel producer.
Scope of Work: To design & manufacture the equipment to the customer's specific requirements, following
independent structural engineers criteria, considering material specification, surface preparation, protective
coatings and the friction grip / through hardened type fixing arrangements necessary to safely suspend all the
equipment from the cranes gantry beams - all programmed to meet a very short delivery time-scale for
installation during the customer's summer shut-down period.
Design Considerations: -
• All items to be of a robust and durable design, suitable for operation in the noisy, dirty & dusty conditions
associated with this heavy industry, and fit for purpose in providing a safe working environment for
operators and maintenance personnel alike, whilst reducing internal crane cab noise levels.
• Electrical Houses comprised of a structural steel skeleton over-clad in heavy gauge steel plate (fully
stiffened to accommodate control panels & electrical switchgear) with personnel / emergency exit door, a
central gangway complete with stanchions, handrailing etc., an internal runway beam & electrical hoist,
numerous sealed service(s) apertures and electrical safety matting to floor.
• DSL Cages manufactured in a similar fashion to the Electrical Houses, designed to carry the necessary
equipment to facilitate the transfer of electrical power from the `Down Shop Lead / Busbar' system.
• Crane Cabs comprised of a complex structural steel skeleton with acoustic infill panels & personnel door,
protected by a heat shield suspended beneath, and fitted with inward-opening (for cleaning from within the
cab) triple-glazed projectile-safe windows to walls & floor areas (safety grilles at floor level) having
sacrificial outer panes - all to provide the correct lines of vision. Installation of lighting & power, an internal
monorail system & electric chain hoist, ventilation ports for integration with an existing air conditioning
system, rubber floor matting, operator swivel chair & trainee's fold-up seat completed the turnkey package.
Acoustic Performance: An external noise level of 95dB(A) was reduced to 65dB(A) inside the Crane Cab, well
below the customer target noise level of 70dBA and the First Exposure Action Level (80dBA) of the Control of
Noise At Work Regulations 2005, reducing the operator's daily noise exposure and allowing him to effectively
communicate by radio in a stress-free, comfortable environment.
