If you have any questions about wire splicing or related crane or hoist issues, feel free to reach out to me at (904) 430-3598 or Jeramy Nichols It will cost you more in the end in terms of safety and performance and will most likely create the inconvenience of re-breaking down the line, anyways. If you’re replacing components, especially if they have repetitive issues, you’ll need to look downline to make sure you’re addressing the root cause of the issue.įor best results, we recommend replacing your hoist power wire when it breaks and avoid the temptation for a quick, cheap and easy fix like wire splicing. If you’re splicing due to deterioration in your wire, you’re likely to be chasing ghost issues going forward. Internal breakage can result in intermittent control issues affecting crane motions or power issues causing single phasing to motors and premature failure. Beware that if any spliced wiring were to come apart, it could create a potential shock hazard for the crane operator!Įven without splicing, power and control cable can become brittle and lose connectivity due to internal breakage caused by aging or environmental fatigue. Also, there are dangers associated with wire splicing. The more splices you have made in your wiring, the more your voltage and amps will drop because you won't have a smooth, continuous current running through it. There are other drawbacks to wire splicing as well. They are not appropriate for hoist wiring. Wire connections using wire nuts need to be terminated in a fire-resistant box. This would create a grave danger in highly combustible working environments. If you are not cautious and allow these wires to stay in the open, then those sparks could cause a fire. Also, if the connecting wires become overloaded or loose, they can overheat and cause sparks. A connection like this would not hold the needed tensile strength. Splicing with wire nuts, or what they call “butt splices”, where wire connectors are slipped onto the ends of wire and twisted together, are not recommended at all. In the same way, you’ll want to make sure that anyįestoon wiring you use for your crane’s hoist has the proper flexibility needed.

The spliced wiring is not going to be strong enough to hold together. Imagine if you had an extension cord and you cut it and spliced the wire within it together then pulled on either end. If spliced, the hoist wire loses the strain relief normally provided by its insulated outer coating and it could break if stress is put on it.Įxamples of compromising spliced hoist wires. Since the hoist trolley moves back and forth on a crane’s I-beam, it requires any attached wiring to be flexible enough to accommodate the range of motion.

National Electric Code NEC/NFPA 70-610.21(g), as well as other regulatory agencies and original equipment manufacturers, it is not advisable to splice the wire that feeds power to your crane’s hoist. Splicing, in practice, allows you to avoid installing new wires by connecting used, damaged ones-a quick and dirty alternative to investing in new wire. Splicing is the process of combining two different pieces of wire together to form one continuous wire that will carry an electrical current. HOIST CLINIC WITH ACE INSPECTION MANAGER JERAMY NICHOLS Pendant Control Inserts, Switches, and Accessories.If the extension of the wire is beyond 100 feet, consider replacing the wire with a thicker size.

You can splice 2 differently-sized wires together, as long as they're close in gauge (like 18AWG and 16AWG).16 gauge is also common, especially for distances up to 50 ft (15 m). 18 gauge (AWG) is the most popular size, and it's usually used for distances of up to 25 ft (7.6 m). Speaker wire ranges from 10AWG (which is very thick) to 20AWG (which is very thin).You can also cut a small piece of the wire and take it with you to a store that sells audio supplies so they can tell you.The number that's printed beside that hole is the wire gauge. If yours doesn't, place the wire in the holes of your wire cutter until you find the hole it fits in most closely. Some wires will have the gauge printed down the side of the wire. For the best sound results, use stranded (not solid) speaker wire that's the same gauge (AWG) as your existing wire. Match the size of your replacement and existing wire.
