She neared him as she spoke, pausing close enough that she had to crane her head back to meet his gaze.
He eschewed the pulpit and stood in front of the altar, looking like a caricature of Ichabod Crane, gaunt and gangling, but the words from his mouth were pure silver.
Ower This fact has led to the introduction of the " crane rated " required.
Crane-driving, and it is probable that improvements in single and two-phase motors will eventually largely increase their use for this class of work.
Tests of the comparative efficiencies of hydraulic and electric cranes tend to show that, although they do not vary to any very considerable extent with full load, yet the efficiency of the hydraulic crane falls away very much more rapidly than that of the electric crane when working on smaller loads.
Crane would lift with a speed of about 200 ft.
Per minute, and 100-ton crane with a speed of about 8 ft.
There are many other important points of crane construction too numerous to mention here, but it may be said generally that the advent of electricity has tended to increase speeds, and in consequence great attention is paid to all details that reduce friction and wear, such as roller and ball bearings and improved methods of lubrication; and, as in all other quick-running machinery, great stress has to be laid on accuracy of workmanship. The machinery, thus being of a higher class, requires more protection, and cranes that work in the open are now fitted with elaborate crane-houses or cabins, furnished with weather-tight doors and windows, and more care is taken to provide proper platforms, hand-rails and ladders of access, and also guards for the revolving parts of gearing.
4 is a diagram of a fixed hand revolving jib crane, of moderate size, as used in railway goods yards Fixed and similar places.
There was a strong crane-post, or pillar, around which the crane revolves.
Load is suspended from the crane jib; this jib is attached at the lower end to the side frames, and the upper end is supported by tierods, connected to the framework, the whole revolving together.
This is a very good and comparatively cheap form of crane, where a long and variable radius is required, but it cannot slew through a complete circle.
13 shows an electric crane of this class.
The crane is associated with her as an indicator of the weather.
The crane is a large and strong bird.
