Hinge cartridge specification

• 20% plus increased mechanical strength: the new die casting process provides greater mechanical properties (LM25 sand cast: 230 N/mm2, compared to LM25 gravity die: 280N/mm2)

• Locking mechanism: securely locks the column in the folded position so it can not spring back up during lantern maintenance

• Counter balance spring: the design incorporates a powerful spring; this works with the operator when using the unit to both lower and raise the column

• Adjustable spring loading: the standard counter balance spring can be adjusted to accommodate the vast majority of different lantern weights (up to a maximum of 25Kgs)

• Cable entry: this is through the centre of the hinge cartridge; as it is completely isolated from any moving parts there is no chance of cable damage when raising or lowering the column.

Patent number: GB2411913

To produce a superior design you need to take into account operation and maintenance.  All the components are self contained and do not need to be removed to operate the mechanism.  Which all helps to provide a product that is easily and safely operated by one person.

Column specification

• Elongated Press Stressed Inner Tube: this increases the wall section by 100% from the base of the hinge cartridge down to below ground level; this is fully compliant with a Type 5 pressed stressed inner tube in the EN 40 standard

• No welds in the column structure nor build: welding applies localised heat which can affect the structure and weaken the metal

• Corrosion resistant: when aluminium is exposed to the air, the surface oxidises and forms a protective boundary layer; this slows down oxidisation to a negligible effect in most circumstances

• High quality decorative finishes: anodised, painted or powder coated finishes are available.
