What is a festoon system?
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.
What is a festoon on a hoist?
FESTOON SYSTEMS: Festoon systems support the conductor cables and applications to the crane equipment. The festoon carriers can support large quantities of control, data and optic fiber cables, traveling independently from the mobile machinery with control carriers.
What is a festoon on a crane?
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 festoon cable?
Festoon cable products are flat, portable cords designed for use in cranes and festoon systems that perform excellently while enduring extreme flexing and difficult environmental elements.
What is a conductor bar system?
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.
What is a conductor bar?
Why should the hook be positioned directly over the load when attaching the load?
When rigging and lifting a load, it is important the hook is correctly positioned where the weight of the object listed is applied in the bowl or saddle of the hook. Side, back and or tip loading are conditions that reduce the hook’s lifting capacity and can cause damage to the hook (see illustration below).
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 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 is the work of a crane operator?
Crane operators operate cranes or draglines to lift, move, position or place machinery, equipment and other large objects at construction or industrial sites, ports, railway yards, surface mines and other similar locations. They are employed by construction, industrial, mining, cargo handling and railway companies.
What is a conductor bar made of?
Conductor bars consist of a rigid conductor bar constructed from formed galvanized steel, copper, or stainless steel depending on the application and amperage requirement.
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.
What is the most common misuse of rigging a?
With rigging hardware, what we’re talking about is items like hooks, links, shackles, turnbuckles, eye bolts, and hoist rings. The most common problems tie back to misuse and abuse and lack of inspection. Some of the most common issues we see are: Hooks with missing or broken latches.
Can you leave a suspended load on a crane?
When a load of any kind is to be suspended for any considerable length of time, make sure the brake is firmly applied. Never leave cranes unattended while the load is suspended unless the load is suspended over water, a barricaded area, or blocked up or otherwise supported from below during repairs or emergency.
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 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)].
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 purpose of busbar?
What is the Purpose of a Busbar? A busbar is an electrical junction used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders. The main purpose of a busbar is to carry electricity and distribute it. Busbars are used to make the systems more efficient.
What is a crane driver called?
Alternative titles for this job include Mobile crane driver, tower crane operator.
What are the skills of a crane operator?
Crane Operator Skills
- Excellent manual dexterity, flexibility and physical strength.
- Mechanical knowledge of the design and use of equipment they work with, as well as the ability to make minor repairs.
- Excellent depth perception, hand-eye coordination and a fast reaction time.
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 are the three main parts of a crane?
Cranes consist of four key components:
- Hook. The hook element of a crane is the part that holds or carries the load and connects it to the hoisting element.
- Hoist. The hoist element of a crane provides the vertical lifting and lowering power.
- Trolley.
- Bridge.
What are six 6 defects that will condemn a lifting chain?
Chain links
Using a chain incorrectly can cause damage such as cracks, breaks, stretched links or fittings, excessive wear, nicks, gouges and rigid chain links or fittings. The simplest way to prevent any damage to your chain is to ensure you follow the WLL for the chain, this should be visible on the ID tag.
What is difference between lifting and rigging?
Rigging equipment includes chains, wire ropes, slings, connections, fittings, end attachments, and other equipment. In comparison, lifting hardware is a subset of rigging hardware that is designed for the vertical movement of loads.
How many signal persons for a crane?
one person
Only one person may give signals to a crane/derrick at a time, except in circumstances covered by paragraph (j) of this section. [Reserved.] Anyone who becomes aware of a safety problem must alert the operator or signal person by giving the stop or emergency stop signal.
