Company History and Qualifications

The John King Company was established in Leeds, England in 1926. Early success was achieved in the
manufacture of mechanical handling equipment for the rapid mechanisation of the coal industry. In
these early days conveyor chain was generally of cast link construction. The Company therefore has
unrivalled experience in the production of highest quality cast link chains in ductile irons and steel under
the “Climax Quality Brand”. JOHN KING are undoubtedly the world leaders in this range of conveying
chains.

Although cast link chains remain an important part of the JOHN KING programme, the company
has progressively expanded the product range to encompass chains of other constructions and
manufacturing techniques including Welded steel chains, engineered steel chains, forged fork link chains
and Engineering plastic chains.

Today JOHN KING offer the widest range of conveyor chains of any manufacturer which makes them
unique in being able to offer an infinite number of chain types in a variety of materials and constructions
for a multiplicity of industry mechanical handling applications.

In recent years it has been JOHN KING’s strategy to develop the Company into a global business. This
has seen the establishment, in addition to the main factory in England, distribution Companies in North
and South America, Africa, South East Asia and Central Europe. Our objective is to provide best service
in supply of high quality chain and sprockets Worldwide.

All products are manufactured within the dictates of the Company’s quality management according to
ISO 9000 establishing consistent and high quality products and ensuring performance reliability and
extended service life.

We are pleased to present our Forged Fork Link catalogue detailing the most comprehensive range of
chains of this series together with ancillary equipment including sprockets, idlers, wear rails and flight
bars in the market. We look forward to working with you in the future.

Forged Link Standard Series

This series represents the leading product within

the John King programme. Forged fork link chain
has proven to be one of the most reliable conveying
mediums offering a combination of versality, strength
and abrasion resistance. These chains, originally
of european origin, are now established worldwide.
With a wide variety of materials, heat treatments
and flight formats the chain is proven in both drag
and enmasse handling.

Forged Link Double Series

For double strand assemblies John King have

a range of links following the standard format but
with a forged “double clevis” into which a scraper
can be mounted. The flight blade can be retained
by either a U bolt or standard fasteners. The chain
allows for some built in clearance between strands
which obviates any potential problems that may be
associated with mismatch. Double strand allows for
improved discharge particularly relevant in conveying
sticky materials.

Forged Link Triple Series

Where extra wide flights are required the John King

triple link is available allowing, in conjunction with
the double on perimeters, three chain strands up to
3100 mm overall. In addition the “Double slot” allows
for a versatile means or flight retention for both steel
& plastic options. Retention can be either U clips or
standard fasteners.

High Manganese Wear Rail

The standard recommendation for forged chain wear rail is manganese steel, an austenitic structure, offering unique
work hardening properties. In its rolled condition it offers a hardness value of 200-220 Bnh increasing up to 600 Bnh if
the optimum conditions prevail.
