Wait until Fred gets a load of this!
Transporters can only move the load to any point on a vertical surface (generally a plane surface); they have a lifting Trans- motion and a movement of translation.
Motor, with a given load factor.
It is almost no effort for me to row around the lake, no matter how heavy the load may be.
The cedar tree was bent over with the weight of a heavy load of wet snow.
In the first the load can be lifted vertically, and then moved round a central pivot, so as to be deposited at any convenient point within the range.
In electric cranes a useful method is to arrange the connexions so that the lifting motor acts as a dynamo, and, driven by the energy of the falling load, generates a current which is converted into heat by being passed through resistances.
In the latter case the overturning tendency begins as soon as the load leaves the ground, but ceases as soon as the load again touches the ground and thus relieves the crane of the extra weight, whereas overturning backwards is caused either by the reaction of a chain breaking or by excessive counterweight.
In order that only one motor may be used, and also that the load may be lifted by a single part of rope, various devices have been invented.
A second time it tried to carry its load up the rough trunk of the tree, and a second time it failed.
Sorting the clothes, she put a load in the washer and started it.
Strictly speaking, the name alludes to the arm or jib from which the load to be moved is suspended, but it is now used in a wider sense to include the whole mechanism by which a load is raised vertically and moved horizontally.
That the quantity of heat to be got rid of may become very considerable is seen when it is considered that the energy of a load of 60 tons descending through 50 ft.
The actual load factor to be chosen depends on the nature of the work and the kind of crane.
A dock-side crane unloading cargo with high lifts following one another in rapid succession will require a higher load factor than a workshop traveller with a very short lift and only a very occasional maximum load; and a traveller with a very long longitudinal travel will require a higher load factor for the travelling motor than for the lifting motor.
The derrick crane introduces a problem for which many solutions have been sought, that of preventing the load from being lifted or lowered when the jib is pivoted up or down to alter the radius.
To keep the load level, there are various devices for automatically coupling the jibraising and the load-lowering motions.
The Titan was the first type of large portable crane in which full use was made of a truly horizontal movement of the load; for the purpose for which the type is designed, viz.
On arriving at a certain height the lift ceases and the jenny is released, and by the continued pull of the rope, it runs up the jib; on arriving at an adjustable stop, the jenny is again locked, and the load can be lowered out; the hook can then be raised, when the jenny is automatically unlocked, and on paying out the rope the jenny gravitates to its first position, when the load is lowered and the cycle repeated.
Vessels go to Porman to land coke and coal, and to load iron ore and lead.
At its opening, on the 27th of September 1825, a train of thirtyfour vehicles, making a gross load of about go tons, was drawn by one engine driven by Stephenson, with a signalman on horseback in advance..
In practice the gradient should not exceed i in 221, and even that is too steep, since theoretical conditions cannot always be realized; a wet rail will reduce the adhesion, and the gradients must be such that some paying load can be hauled in all weathers.
For example, what is a safe speed at a given curve for an engine, truck or coach having the load equally distributed over the wheels may lead to either climbing or overturning if the load is shifted to a diagonal position.
Such an arrangement would be ideally perfect from the point of view of the permanent-way engineer, because it would then be possible to distribute the whole of the load uniformly between the wheels.
Thus an engine working at maximum power may be used to haul a relatively light load at a high speed or a heavy load at a slow speed.
More than likely, it was a load off his mind as well.
It was as if she lifted a load from his shoulders.
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.
This drawback can be corrected to a slight extent by furnishing the hydraulic crane with more than one cylinder, and thus compounding it, but the arrangement does not give the same economical range of load "as in an electric crane.
The ruling gradient of a section of railway is the steepest incline in that section, and is so called because it governs or rules the maximum load that can be placed behind an engine working over that portion of line.
As soon as Rostov heard them, an enormous load of doubt fell from him.
Though a busy colliery may send off its product by the train-load to an important town, the wagons will usually be addressed to a number of different consignees at different depots in different parts of the town, and therefore the train will have to be broken up somewhere short of its destination and its trucks rearranged, together with those of other trains similarly constituted, into fresh trains for conveyance to the various depots.
A station of moderate size may collect goods destined for a great variety of places but not in sufficient quantities to compose a full train-load for any of them, and then it becomes impossible to avoid despatching trains which contain wagons intended for many diverse destinations.
Blenkinsop placed the teeth on the outer side of one of the running rails, and his reason for adopting a rack was the belief that an engine with smooth wheels running on smooth rails would not have sufficient adhesion to draw the load required.
Of these there are two main systems: (1) a continuous cable is carried over two main drums at each end of the line, and the motion is derived either (a) from the weight of the descending load or (b) from a motor acting on one of the main drums; (2) each end of the cable is attached to wagons, one set of which accordingly ascends as the other descends.
An ill-balanced load also exaggerates " plunging," and if the period of oscillation of the load happens to agree with the changes of contour or other inequalities of the track vibrations of a dangerous character, giving rise to so-called " sinuous " motion, may occur.
An hour; subsequently it drew an average gross load of 40 tons behind the tender at 13.3 m.
Relieved from its load it does not, like other animals, seek the shade, even when that is to be found, but prefers to kneel beside its burden in the broad glare of the sun, seeming to luxuriate in the burning sand.
In the other class of transporter the load is not usually moved; FIG.
2 t), the load to be lifted being suspended from a small travelling carriage which runs on the lower flange.
This is effected by slinging the load to an eye or Lifting hook, and elevating the hook vertically.
2 gives a lift of load four times the stroke of the cylinder.
