Nettings

Commonly Used in Construction, fishing, Transportation and even recreational sports.

Construction safety nets


Construction Safety Nets are used at high-rise building construction sites for preventing accidental fall of people or objects from the site. Construction safety nets are the safest and cost effective fall prevention system in the world. Construction safety nets are flexible plastic nets made from HDPE or High-density polyethylene raw materials.


Construction safety netting system is also known as debris netting which can be installed both horizontally or vertically according to the requirements. The best practice of construction netting is to wrap up the whole construction site from bottom to top, which works as a protection wall to prevent anything from falling without blocking the view. Safety net installation at any building site requires professional expertise and technical knowledge.

" The best practice of construction netting is to wrap up the whole construction site from bottom to top.. "

A different type of safety-net, gives falling objects much more time to come to rest than hitting hard ground directly. In physical terms, this means more time for deceleration and kinetic energy transfer, resulting in a softer landing and much lower risk of damage.

What kind of net to be used, depends upon many factors, (such as the factors that could determine force of the impact) such as falling objects speed and mass.


To encounter more force, a more total width of the net, is required. The minimum-distance of the spot on net at which object impacted, and the edge of net (nearest-edge), matters, and to be kept more than certain limit. There is role of materials used to make the ropes of net (such as an iron rod grid will not work as good as flexible and extensible ropes), and the tension or stretch used to make the net (stored in the ropes), also have some roles.


The net is to be set at an appropriate height from the hard ground, so that the object, along with the rope, does not clash with the hard ground. The mesh hole size should-not be so big that falling object/people/part of it could pass through the holes.


Fishing Nets


The oldest known fishing net is the net of Antrea, found with other fishing equipment in the Karelian town of Antrea, Finland, in 1913."

Fishing nets have been used widely in the past, including by stone age societies. The oldest known fishing net is the net of Antrea, found with other fishing equipment in the Karelian town of Antrea, Finland, in 1913. The net was made from willow, and dates back to 8300 BC. Recently, fishing net sinkers from 27,000 BC were discovered in Korea, making them the oldest fishing implements discovered, to date, in the world. The remnants of another fishing net dates back to the late Mesolithic, and were found together with sinkers at the bottom of a former sea.


Bottom Trawls


A trawl is a large net, conical in shape, designed to be towed along the sea bottom. The trawl is pulled through the water by one or more boats, called trawlers or draggers. The activity of pulling the trawl through the water is called trawling or dragging. Bottom trawling results in a lot of bycatch and can damage the sea floor.


A single pass along the seafloor can remove 5 to 25% of the seabed life. A 2005 report of the UN Millennium Project, commissioned by UN Secretary-General Kofi Annan, recommended the elimination of bottom trawling on the high seas by 2006 to protect seamounts and other ecologically sensitive habitats. In mid-October 2006, US President Bush joined other world leaders calling for a moratorium on deep-sea trawling.


Purse seine

The purse seine, widely used by commercial fishermen, is an evolution of the surround net, which in turn is an evolution of the seine net.


A large net is used to surround fish, typically an entire fish school, on all sides. The bottom of the net is then closed by pulling a line arranged like a drawstring used to close the mouth of a purse. This completely traps the fish.


Trammel

A trammel is a fishing net with three layers of netting that is used to entangle fish or crustacea. A slack central layer with a small mesh is sandwiched between two taut outer layers with a much larger mesh. The net is kept vertical by the floats on the headrope and weights on the bottom rope. Floats can be small, cylindrical or egg-shaped, solid and plastic.


They are attached on the head rope while weights made up of lead are distributed along the ground rope.


Cargo Nets

A cargo net is a type of net. It is usually square or rectangle, but sometimes round, made of thick rope, with cinch ropes extending from the corners, and in some designs, the edges. It is named for its use in transferring cargo to and from ships.

Cargo Transfer

In shipping, cargo lift nets are used to load and unload cargo. The net is spread out by stevedores, who load the goods onto it. They then attach the cinches to a crane hook. Lifting the hook draws the corners of the net around the cargo.


This results in a balanced and secure load which can be safely hoisted. Goods are transferred from one place to another in the construction industry using cargo nets. When used to transfer cargo by helicopter, they are referred to as "underslung" cargo nets.

Cargo nets are used by the military, and in the shipping industry, to secure loads to prevent them from shifting during transport, as well as to deter theft.


Obstacle courses

As part of obstacle courses, cargo nets are used as flexible ladders.


Obstacle courses have been used by the military to train soldiers as far back as the ancient Greeks. These courses, however, were primarily used for the training of extremely fit individuals and not necessarily aimed at the development of the whole person as is common practice on ropes courses today.


Ropes course programs can be designed to meet a number of educational, developmental, and recreational goals. High ropes course and climbing programs generally focus on personal achievements and ask participants to confront their personal fears and anxieties. Challenges may be physical and/or emotional. In certain cases, high element programs involve the development and mastery of technical skills to manage rope belay systems used to secure other climbers as they move through the course.


In such cases, outcomes often include exploring the fundamentals of trust, craftsmanship, and coaching. Programs using low ropes course elements or group initiatives are most often designed to explore group interaction, problem-solving, and leadership.


Recreational Sports


Driving Range

"In urban and suburban areas, large nets protect surrounding people and structures from errant balls. "

A driving range is a facility or area where golfers can practice their golf swing. It can also be a recreational activity itself for amateur golfers or when enough time for a full game is not available. Many golf courses have a driving range attached and they are also found as stand-alone facilities, especially in urban areas. They are typically run by businesses or sometimes by universities. Distances are usually marked by target greens at regular distances. Driving ranges may have natural grass, similar to a golf course, or players may use synthetic mats that resemble real turf.


In urban and suburban areas, large nets protect surrounding people and structures from errant balls. Driving ranges are particularly popular in Japan where golf courses are overcrowded and often very expensive.


Many commercial driving ranges are seen in conjunction with other sports-related practice areas such as batting cages or miniature golf. Some driving ranges also offer areas for practice chip shots, bunker shots, and putting.
