All sail being set, he now cast loose the life-line, reserved for swaying him to the main royal-mast head; and in a few moments they were hoisting him thither, when, while but two thirds of the way aloft, and while peering ahead through the horizontal vacancy between the main-top-sail and top-gallant-sail, he raised a gull-like cry in the air.
Accordingly, the boats now made for her, and were soon swayed up to their cranes--the two parts of the wrecked boat having been previously secured by her--and then hoisting everything to her side, and stacking her canvas high up, and sideways outstretching it with stun-sails, like the double-jointed wings of an albatross; the Pequod bore down in the leeward wake of Moby-Dick.
The latter consists of a framework carrying the hoisting barrel, with its driving motor and gearing, and a travelling motor, which is geared to the running wheels in such a manner as to be able to propel the whole machine; FIG.
The maximum load on the engine is thus greater and more power is required than for fixed drums. Steam consumption is economized, whenever possible, by throwing in the clutches of both drums and hoisting in balance.
Carrying the grooved sheaves over 'which the hoisting ropes pass, is known as the head-gear (fig.
That whale of Stubb's, so dearly purchased, was duly brought to the Pequod's side, where all those cutting and hoisting operations previously detailed, were regularly gone through, even to the baling of the Heidelburgh Tun, or Case.
Fixed drums are best for mines in which the hoisting is done chiefly from one level; independent drums when there are a number of different levels.
The variations in engine load are thus reduced, and incidentally hoisting time is saved.
The heavers forward now resume their song, and while the one tackle is peeling and hoisting a second strip from the whale, the other is slowly slackened away, and down goes the first strip through the main hatchway right beneath, into an unfurnished parlor called the blubber-room.
The principal motion in a crane is naturally the hoisting or lifting motion.
