Cranes






Cranes – Design, Practice, and

Maintenance

(2nd Edition)

by

Ing. J. Verschoof


Foreword

This book looks at all types of cranes and deals with container and

grab unloader cranes in some detail.

The objective has been to give a general overview of this very wide

subject and then to provide positive, practical guidance to anyone

involved in the design, specification, selection, or operation and maintenance

of cranes.

A crane is often a very large and complex piece of equipment and

this book analyses many of the individual components and design features

that can be found on a typical crane. Components such as brakes,

wire ropes, electrical drive systems, automatic sensors, wheels, rails,

buffers, cable reels, festoons, hoppers, overload preventers, and anticollision

systems are discussed in some detail along with advantages

and disadvantages of various component types. This book also shows

how to correctly ‘size’ and calculate a number of these components.

Furthermore, various design features and preferred solutions are discussed

such as the effect of wind on cranes, design standards, welding

methods, structural design and fatigue calculations and, finally, maintenance.

Anyone involved in crane specification, selection, operation, and

maintenance should find the level of detail invaluable when considering

potential problem areas, especially some of the ‘rule of thumb’ recommendations.

Crane manufacturers facing problems of detail design will

find this book useful in understanding the overall background and

environment in which cranes work.
