A working manual to assist engineers, consultants, mechanics, surveyors and sales teams actively involved in the art of lift modernization.

U.K. lift expert Roger Howkins has joined with ELEVATOR WORLD to produce The LiftModernisation Design Guide, designed to guide the planning of a lift modernization in the most economical way (in terms of preparation time). The notebook is designed, Howkins notes, as a working tool, a living document which can receive additions when specific information has been gathered.

Howkins suggests multiple journeys to the project site can be avoided by asking the correct questions at the appropriate time and in a logical sequence, and he then relates the proper queries and timing to guide the reader. In addition, items "missed during initial survey" can be avoided almost completely, as Howkins assures that asking the right questions at the tight time will ensure such instances are kept to the absolute minimum. The lift modernization has been divided into nine specific work stages, with data sheets covering each step in detail. The systematic approach is intended to ensure that project designers will not flit from stage to stage without purpose, possibly failing to answer the specific question and missing a vital component that requires overhaul, replacement or discussion with a member of the design team.Table of Contents

The guide has been designed as a series of loose-leaf pages in a design-guide format that can be referred to by each particular section. Checklists include an area for specific comments, where the user may note the need for further investigation. Readers are also provided with many areas for sketches, notes or even "cryptic notes" which may not be vital for the initial survey but may assist colleagues in the future, though the use of these pages is at the discretion of the reader. In case of unfamiliarity with a certain component, drawings have also been included, denoting where the component is typically located. Howkins intends for the book to accompany field personnel to jobsites, noting that if it is purchased and gets oily finger prints and dog-eared pages, it is fulfilling its duty - to assist, educate and enhance the art of lift modernization. As lifts considered new today will require modernization at some point in the future, Howkins' notebook is intended to be updated with new and revised pages as and when required.

This reference tool is designed for the assistance of engineers, consultants, mechanics, surveyors and sales teams who are actively involved in the art of lift modernization.
