It is not intended for continuous working mode. So most crane works with a 40% duty cycle full-load factor. 1. lowing the hook, 2. lifting the load, 3. carrying the load, and 4. lowering the load. dixon_robert@Yahoo.com I am presently researching on the most suitable motor for 35,000Kg/ 55KW full-load with vector control technology. Looking for help too....

∙ 15y agoDuty means loading the motor with one or more loads and the loads will remain constant for specified period and sometimes different loads in which speed varies. there are S1 to S9 duty cycles. and Cyclic duration factor is = (total time contributes to electric heating *100)/total cyclic time

What is crane engine?
An engine specifically designed or adapted to Cranes. One such model is a Big Cummins Diesel that has twelve cylinders and is rated at 635 maybe 685 HP and is available standard on certain marques and models of heavy-duty crane. with a 200 foot boom, l50 ton lifts are well within the duty cycle!
What is the relationship between output voltage and duty cycle in a step down chopper?
If you have a cigar lighter to USB power converter used in your automobile to charge from a USB bus that fits in your car cigar lighter, the USB voltage is 5V. The car is 12V. So there is a switch to turn it on for 5 ticks and off for 7 ticks 42% duty cycle if you wanted 1.2V 10% duty cycle
A pulsed laser produces 47mj per pulse. The pulse repetition time is 2.5ms and the duty cycle is .008. Find the pulse duration?
(shiwwasuji@gmail.com)Duty Cycle DC is the ratio of pulse duration to the pulse repetition time periodDuty Cycle DC = pulse duration (t)/pulse repetition time period (T)Pulse Duration (t) = 0.008 x 2.5 ms
How do you calculate the width of the pulse in a pulse width modulation?
i'm not really sure, but if i'm not mistaken, you should know the frequency of the PWM and it's duty cycle. For an example, if f = 10khz & duty cycle = 90%. f=1/t, so t=100microsecond, 90/100 x 100microsecond = 90microsecond. So the width of PWM is 90microsecond
Can all dc motors be speed controlled?
A: YES it will however the most reasonable solution would be to keep frequency fix and change the duty cycle
What is the deduction of crane ratings in duty cycle?
50%
S1 duty cycle?
S1 duty cycle for an electric motor means the motor is configured for continuous running, which means the motor runs long enough to come to full temperature and then rest long enough to fully cool before starting operation again.

What is Duty cycle in digital logic?
duty cycle is the total on peeriod in one complete cycle.
What is the Definition of continious duty motor?
A continuous duty motor is one which is never turned off.
What is full load current of 20 HP induction motor in delta?
480V about 20A 240V about 40A look at the nameplate duty cycle and efficiencies vary
Are excise taxes included in the duty for an imported crane from Canada?
Very unlikely.
What is duty cycle in radar?
Duty cycle is the fraction of time that a system is in an “active” state. ... The transmitter runs for one out of 100 microseconds or 1/100 of the time, and its duty cycle is therefore 1/100, or 1 percent. The duty cycle is used to calculate both the peak power and average power of radar system.
What is the difference between the pulse width and the duty cycle of an injector?
Pulse width is the time in milliseconds that the injector is energized, the duty cycle is the percentage of on-time to total cycle time
What is a welder's duty cycle?
The terminology in the electrical trade as to duty cycle refers to the amount of "on time" as to the "off time". When referring to equipment that have a high current on time, it is usually using components or wire that are sized smaller than what they should be and can not cool themselves.These components can not dissipate the heat generated quick enough and can only be on for a certain amount of time. This type of equipment is given a duty cycle. The duty cycle has to have an equal or greater off time to let the equipment cool down. It is this ratio of "on time" to "off time" that is the equipment's duty cycle.For example, motors due to their design usually have a 100% duty cycle, meaning that the motor can operate continuously without having to be shut down to allow it to cool off.
What gauge of wire from the panel to the outlet would a 240V 52A rated welder require?
#6 You can use number 6 copper if you wish,you will definitely not overload it or you can figure the wire size by the duty cycle. If your welder has a 100 duty cycle rating use wire good for 52 amps or a number 6. If the duty cycle is 90, multiply the amp draw by .95 x 52 or 49.4 amps or a number 8 wire. These are a few more of the duty cycle multipliers 80 duty cycle(.89) 70 duty cycle(.84) 60 duty cycle(.78)Duty cycle takes in to account that most welders do not weld continously at maximum welder output all the time.
How is width of pulse and power content is related?
The width of a pulse and power are related by a term called duty cycle. Full power means the pulse comes ON and Stays ON continuously for 100% duty cycle. No power means pulse is OFF continuously for a 0% duty cycle. 50% duty cycle means pulse stays ON half the time and OFF half the time. Duty cycle can be used to explain the relationship between pulse and power content.
