Eight hydraulic hoists, of the most up-to-date pattern, are capable of shipping 5,600 tons of coal per hour.
Machines used for lifting only are not called cranes, but winches, lifts or hoists, while the term elevator or conveyor is commonly given to appliances which continuously, not in separate loads, move materials like grain or coal in a vertical, horizontal or diagonal direction.
In geared hoists the drums. are on a separate shaft, driven from the crank-shaft by tooth or friction gearing, and make one revolution for, say, 4 or 5 double strokes.
Large and powerful geared hoists are not uncommon.
We are also able to either provide or arrange hire of riser blocks and seats, commodes, portable hoists and electric scooters.
