Our company policy is flexible and is typified by out emphasis on incorporating indigenous manufactured components into our design concept.

Manufacturing Drawings

A.D.L can produce detailed manufacturing drawings for any item of equipment associated with the alluvial mineral recovery. An initial design assembly drawing is prepared from which individual component drawings are detailed, specifying the number required, component material and any other relevant information required to facilitate construction. All drawings are prepared in consultation with British Standards or any equiliant standard required by the client.

Engineering Specifications

A.D.L. produce detailed specifications in compliance with every manufacturing drawing. An assembly specification is produced which lists the specification and drawing number for each item along with full assembly instructions. From this an itemised technical spcification is produced which details dimensions, weight, material tolerances, finish and any other specific instructions, thus ensuring complience with the initial design concept.

Procurement & Inspection

A.D.L. can also act on behalf of the client to source associated components. Full technical enquiries are issued, progressed and vetted on receipt for compliance to specification, price and delivery.
