MOBILE CRANE MANUAL Compiled and Expanded by: DONALD E. DICKIE, P.Eng. From an Original Concept and Work by: D.H. CAMPBELL, P.Eng. Published by: CONSTRUCTION SAFETY ASSOCIATION OF ONTARIO 74 Victoria Street Toronto, Ontario, Canada MSC 2A5,MOBILE CRANE MANUAL The illustrations in this text are not intended to portray models of cranes actually being pro- duced. Similarities are coincidental and intended only to make the artwork as realistic as possible. We caution users of this text against applying any of the load chart materials to purposes other than intended. The load charts are incomplete and any attempt to use them in actual field situations is highly dangerous. We also caution users of this text that the material contains recommendations, guidelines and procedures that are generally applicable to most mobile cranes, but not all. All makes and models of cranes are distinctly different and each has individual characteristics absolutely essential to safe operation. To learn of these, the manu- facturers' literature must be studied. In the past, members of the public have used printed information that was outdated by sub- ‘sequent improvements in knowledge and tech- nology. We therefore make the following state- ment for their future protection. The information presented here was, to the best of our knowledge, current at time of printing and is intended for general application. This publica- tion is not a definitive guide to government regulations or to practices and procedures wholly applicable under every circumstance. The appro- priate regulations and statutes should be con- sulted. Although the Construction Safety Asso- ciation of Ontario cannot guarantee the accuracy ‘of nor assume liability for the information pre~ sented here, we are pleased to answer individual requests for counselling and advice. © CONSTRUCTION SAFETY ASSOCIATION OF ONTARIO, 1982 ISBN 0-919465-09-9 [All tights reserved.

More specifically, the manual has been published to provide information crucial in educating and training crane operators and apprentices. Mobile cranes are becoming larger, more expensive and more sophisticated all the time. But the training provided for operators and apprentices has not kept pace with the advances in technology. Itis our sincere hope that the MOBILE CRANE, MANUAL will not only help to define more fully the need for improved training but also provide material essential to the operation of mobile cranes and the understanding and use of load charts by operators. We are grateful to everyone who assisted in the preparation and review of this manual. We particularly appreciate the efforts of Lloyd Spalding for his help with some of the load charts, and Jack Gray for the illustrations.
