A snatch strap is a piece of equipment used to help in the recovery of vehicles bogged in sand or mud.
Snatch straps are manufactured from webbing that is capable of approximately 20% stretch under load. This stretching property allows the strap to store kinetic energy, which is used to pull vehicles from a bog. Snatch straps are typically between 6 and 15 m (20 and 49 ft) in length, with 9 m (30 ft) being a common size. [1] Snatch straps also have ratings of permissible working load - e.g. 8,000 kg.
A snatch strap is used by attaching one end to a rated recovery point on the bogged vehicle (e.g. a recovery hook or loop on the chassis). A second vehicle is required to do the recovery. The snatch strap is laid out on the ground in the direction the bogged vehicle is to be recovered (either forwards or backwards), with an "S" bend in the middle approximately 1m in length.
The recovery vehicle is backed up so that the snatch strap can be attached to a second rated recovery point on the rear of the recovery vehicle. The recovery vehicle then drives off, and the strap begins to stretch, building up potential energy, until the force keeping the vehicle bogged is overcome, at which point the bogged vehicle is pulled forward (or "snatched", hence the name).
Tack is equipment or accessories equipped on horses and other equines in the course of their use as domesticated animals. This equipment includes such items as saddles, stirrups, bridles, halters, reins, bits, and harnesses. Equipping a horse is often referred to as tacking up, and involves putting the tack equipment on the horse. A room to store such equipment, usually near or in a stable, is a tack room.
A semi-trailer truck, is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a type of hitch called a fifth wheel.
A road train, land train or long combination vehicle (LCV) is a trucking vehicle used to move road freight more efficiently than semi-trailer trucks. It consists of a tractor unit and one or more semi-trailers.
Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure. The pilot sits in a harness or in a cocoon-like 'pod' suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.
A winch is a mechanical device that is used to pull in or let out or otherwise adjust the tension of a rope or wire rope.
A block and tackle or only tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads.
A spring is a device consisting of an elastic but largely rigid material bent or molded into a form that can return into shape after being compressed or extended. Springs can store energy when compressed. In everyday use, the term most often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel. An example of a non-metallic spring is the bow, made traditionally of flexible yew wood, which when drawn stores energy to propel an arrow.
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different.
A lifting bag is an item of diving equipment consisting of a robust and air-tight bag with straps, which is used to lift heavy objects underwater by means of the bag's buoyancy. The heavy object can either be moved horizontally underwater by the diver or sent unaccompanied to the surface.
The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. A pair of these provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent. After burnout, they were jettisoned and parachuted into the Atlantic Ocean where they were recovered, examined, refurbished, and reused.
A trailer is an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials.
Strapping, also known as bundling and banding, is the process of applying a strap to an item to combine, stabilize, hold, reinforce, or fasten it. A strap may also be referred to as strapping. Strapping is most commonly used in the packaging industry.
A recovery point is a part of a car which can be used to recover the vehicle if it becomes stuck (bogged).
An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers. Similar systems are also found at land-based airfields for expeditionary or emergency use. Typical systems consist of several steel wire ropes laid across the aircraft landing area, designed to be caught by an aircraft's tailhook. During a normal arrestment, the tailhook engages the wire and the aircraft's kinetic energy is transferred to hydraulic damping systems attached below the carrier deck. There are other related systems that use nets to catch aircraft wings or landing gear. These barricade and barrier systems are only used for emergency arrestments for aircraft without operable tailhooks.
A semi-trailer is a trailer without a front axle. The combination of a semi-trailer and a tractor truck is called a semi-trailer truck.
A flatbed truck is a type of truck the bodywork of which is just an entirely flat, level 'bed' with no sides or roof. This allows for quick and easy loading of goods, and consequently they are used to transport heavy loads that are not delicate or vulnerable to rain, and also for abnormal loads that require more space than is available on a closed body. Flatbed trucks can be either articulated or rigid.
Fall arrest is the form of fall protection which involves the safe stopping of a person already falling. It is one of several forms of fall protection, forms which also include fall guarding and fall restraint.
A horse harness is a device that connects a horse to a horse-drawn vehicle or another type of load to pull. There are two main designs of horse harness: (1) the breast collar or breaststrap, and (2) the full collar or collar-and-hames.
Vehicle recovery is the recovery of any vehicle to another place, generally speaking with a commercial vehicle known as a recovery vehicle, tow truck or spectacle lift.
Breeching ( "britching") is a strap around the haunches of a draft, pack or riding animal. Both under saddle and in harness, breeching engages when an animal slows down or travels downhill and is used to brake or stabilize a load.
