What is a cable festoon systems?
Festoon systems are mobile supports for electrical cables or pneumatic and hydraulic lines that allow the cable to move with a hoist, trolley, or other mobile equipment without fouling. Festoon systems come in a variety of sizes and configurations to handle round or flat cables and hoses.
How do you calculate festoon cable length?
To calculate required festoon cable length, add 10% to the track length, then add the desired hookup lengths for both fixed end and mobile end connections.
What is a festoon rail?
C-Rail Festoon System are used to electrify various types of mobile equipment. They can be designed not only to support and protect flat and round electrical cables, but air and water hoses as well.
What is a crane festoon?
Festoon cables – looped wires, or more commonly flat cable, that carry power and control across a bridge or along a runway or monorail. Cable reels – also known as electrical cord or power reels, these are one of several alternatives for providing power to electric hoists.

What is the minimum diameter of wire for festoon wiring?
Minimum allowable cable saddle diameter is 10 times the O.D. of the largest cable in the cable package.
What is a festoon on a drilling rig?
A typical Festoon system consists of an end clamp which secures the cable or hose at the non-moving end, a tow trolley or control unit trolley which is moved back and forth manually or by a machine, and a series of intermediate trolleys supporting the cable or hose.
What is a conductor bar?
Conductor bar is a safe and economical method to provide electric power to mobile equipment. We were the first to offer “8-bar” insulated conductor bar for crane electrification in the US back in 1952. Now you can choose from six unique systems for virtually any need from 100 to 1500 amperes and more.
Why is it called festoon lighting?
Originally used to describe wreaths and garlands hung at celebrations and banquets, the word “festoon” (from the Latin festum, meaning “feast”) actually refers to the shape the lights make when hung loosely in a “swag”.
What is the maximum length of a festoon lighting without a messenger wire?
Overhead festoon lighting conductors must be supported by messenger wire (with strain insulators) when spans exceed 40 feet [225.6(B)].
What is the minimum size wire for festoon lighting not supported by messenger wire?
Overhead conductors for festoon lighting shall not be smaller than 12 AWG unless the conductors are supported by messenger wires. In all spans exceeding 12 m (40 ft), the conductors shall be supported by messenger wire. The messenger wire shall be supported by strain insulators.
What is the grasshopper on a drilling rig?
A grasshopper is a combination between a horsehead and an air balance. Its pivot is on the end, like an air balance, but it uses counterweights like a horsehead. The weights, however, are in the middle of the walking beam rather than at the end of it.
What are conductor bars made of?
These consist of a series of insulated bars made out of galvanized steel, copper, stainless steel, or aluminum, which transmit electricity through sliding collector assemblies that power the motors, trolleys, hoists, etc. They are typically used on monorails, runways, and bridge crane applications.
What are the parts of an overhead crane?
The Parts of a Crane All you Need to Know
- Hook. The load is supported using a hook which connects to the hoist and to the end effector.
- Hoist. The hoist is what creates the lift in lifting systems by holding, raising, or lowering, the load using wire rope or chains.
- Trolley.
- Bridge.
- Columns.
- Runway.
- End Trucks.
- Electrification.
How long do festoon lights Last?
If you run frequently, I highly recommend LED globes since they will last 40,000 hours. The incandescent festoon lighting is our most affordable option, which is ideal for a short-term application such as a party or a wedding; nevertheless, these will burn out in about 2000 hours.
What is the opposite of festoon?
Antonyms. natural object impropriety improperness unseemliness ill nature maleficence.
What is the minimum size conductor allowed for festoon lighting?
(b) Festoon Lighting.
Overhead conductors for festoon lighting shall not be smaller than 3.5 mm 2 (2.0 mm dia.) unless the conductors are supported by messenger wires. In all spans exceeding 12 m, the conductors shall be supported by messenger wire. The messenger wire shall be supported by strain insulators.
What type of insulation are conductors used for festoon lighting required to have?
thermoplastic type
The insulation of conductors for festoon lighting shall be of the thermoset or thermoplastic type.

How much oil does an oil rig pump a day?
The data is barrels per day per rig. The USA produces 4,577 barrels per day for every active rig while the Middle Ease produces 59,945 barrels per day per rig, down from 140,144 in 2000.
Why is it called a bus bar?
The term busbar, often spelt ‘bus bar’ or ‘buss bar’, is derived from the Latin word ‘omnibus’. It translates into English as “for all” which indicates that busbars carry all of the currents in a particular system.
Is a busbar necessary?
In power-intensive electrical applications, a busbar (often also spelled bus bar or bussbar) is a critical element for conducting significant current levels between functions within the assembly.
What is the end of a crane called?
One of the largest parts of the crane is the boom. You can easily recognize this as the long steel arm that spans the length of the machine. This part of the crane begins at the operator’s cabin and ends at the hook. The boom distributes the weight and provides the necessary height to lift each load.
What is the top of a crane called?
Larger, heavier duty, purpose-built “truck-mounted” cranes are constructed in two parts: the carrier, often called the lower, and the lifting component, which includes the boom, called the upper.
Can you leave LED lights on all the time?
Well-manufactured LED lights are long-lasting and can be left on all day and every day. But that’s not necessarily true of cheaper, and poorly-manufactured LED lights. Unlike traditional types of light, LEDs produce minimal amounts of heat, so they aren’t a risk for starting any fires.
