skid

1. Chiefly US and Canadian one of the logs forming a skidway
2. a support on which heavy objects may be stored and moved short distances by sliding
3. a shoe or drag used to apply pressure to the metal rim of a wheel to act as a brake

Skid

 

the locking of the wheels of a vehicle—for example, a motor vehicle, a streetcar, or railroad rolling stock—while the vehicle is in motion. As a result of such locking, the wheels slide over the bearing surface rather than turn.

A skid occurs when the braking force exceeds the force of adhesion between the wheels and the surface of a road or track, for example, in the presence of glaze ice or after rain. Skidding increases the braking distance and may cause traffic accidents. As a rule, the skidding of the rear wheels of a motor vehicle results in sideslip of the rear axle.

To avoid skids, modern motor vehicles may be equipped with automatic devices that prevent the wheels from locking.

i. An uncoordinated turn in which the airplane moves inside the turn because of an insufficient aileron or excessive rudder.
ii. In helicopters, a fixed tubular landing gear, often provided with small auxiliary wheels to provide ground mobility.
iii. A rigid ski-shaped member projecting ahead of the landing gear to prevent them from nosing over.
iv. A support for the tail-wheel on the ground in airplanes of early years.
v. A member mounted at the bottom of the aft end of the fuselage of an aircraft with a tricycle undercarriage. The skid absorbs the shock and prevents damage to the aircraft structure if the skid touches the ground either on the takeoff or the landing.

To successfully raise the boom without starting the skid steer, you will need to go from a pipe thread to a hydraulic thread on the same hose.
For this study used the information of Forest plan (1998-2007) and extract information of forest skid trail information include: skid trail length (m), Available road (m), Predicted road density (m/hec), Available skid trail density (m/hec) and total of skid trail density (m/hec).
When it's time for planting, you'll find several overseeder and solid-stand seeder attachments that work with the skid loader--mounted on the front no less.
Skid loaders are also short on ground clearance compared with a farm tractor, so windrowing hay or cultivating row crops would be difficult, if not impossible, to accomplish efficiently, even if specialized attachments were available.
For large jobs where a lot of material needs to be moved, a skid steer would be too small," says Georg Seyrlehner, general manager of earth moving product management at Liebherr Construction Equipment Co.
The forces that can break the grip of the tyres on the road and cause a skid are:
Understeering is when a car underperforms to your steering and the front tires skid; over steering is when a car overperforms and the rear tires skid.
It is important not to cross your arms over the steering wheel and keep your hands in the correct driving position, she says, or there is a chance of breaking your arms as the wheel spins furiously during a skid.
Communication to overhead systems is available to define current stock identification, skid information and stacking information.
After seeing skid after skid of raw lumber stockpiled in the yards of some area sawmills because of the lumber dispute, Canfield says it is high time area wood producers convert their primary production of dimensional lumber into finished consumer products.
