(This illustration shows a part of a crane on the erecting floor of
the manufacturer. There are no exposed revolving parts throughout the
entire length of the crane bridge. Some of the safety features are as
follows: A--inclosed gearing; B--inclosed drive-shaft coupling; C--pipe
inclosure for drive shaft; D--device for sanding rails when crane is
used out-of-doors. See also Fig. 13.)]
Keep all tools, oil-cans, and waste in a closed metal box securely
fastened to the crane or to the runway at some convenient point.
Careful, watchful, intelligent, and trustworthy crane operators,
floormen, and repairmen, can do a great deal toward preventing
accidents, and only such men should be employed about cranes. The
following suggestions relate to the work of these men, and if
faithfully followed will be the means of promoting safety in a marked
degree.
