Elevators may be a cable type, or a hydraulic type. With a cable type, a counterweight balances the weight of the car, The motor moves the cables that pull the balanced car up or down the shaft. The hydraulic type is used for many low elevators (4 floors or less) A motor turns a hydraulic pump that moves a piston up or down, moving the car up or down.
What else can I help you with?
A fully loaded slow-moving freight elevator has a cab with a total mass of 1400 kg which is required to travel upward 45 m in 4.7 min starting and ending at rest The elevator's counterweight has a?
The elevator's counterweight must have a mass of 1400 kg in order to balance the loaded cab. The work done is given by W = F*d, where F is the force required to lift the cab and d is the distance traveled. Using this, we can calculate the work done by the elevator to lift the cab upward 45 m. The elevator's power output can also be calculated using the work done and the time taken to complete the task.
What would have greater power an elevator or stairs?
Stairs have no power at all. They simply make it possible for you to direct your own power in a direction that will accomplish a certain result when you use them. Elevators use electrical power and deliver it in a mechanical form for your use.
How much work does an elevator motor do to lift a 1000 kg elevator a height of 100 m and how much power must the motor supply to do this in 50 s at constant speed?
The work done by the elevator motor to lift the 1000 kg elevator a height of 100 m is 1000 kg * 9.8 m/s^2 * 100 m = 980,000 J. The power required to do this in 50 s at constant speed is 980,000 J / 50 s = 19,600 W or 19.6 kW.
What energy does a plug use?
A plug typically uses electrical energy to power devices when connected to an outlet. The electrical energy is converted into the necessary form of energy required by the device, such as light energy for a lamp or kinetic energy for a motor.
What kind of energy does an elevator use?
An elevator typically uses electrical energy to power its motor and move the elevator car up and down. Some modern elevators may also use regenerative braking systems to recapture and reuse energy during operation.
What type of electrical power is required for elevator use in bldg?
What type of power do elevators require?
Which type of radiation predominates within an enclosed elevator descending into a uranium mine?
Gamma rays would predominate in an enclosed elevator descending into a uranium mine.
How much electrical power is required to run this steam cleaner?
This steam cleaner does not use any electrical power.
What qualification is required to bd a xen in wapda pak?
Msc electrical (power)
What is the power of an electrical appliance?
It depends on the appliance. All appliances are required to have a 'nameplate' which contains information on their power and voltage ratings.
How do you power up the elevator on steam works?
All you have to do is use the old steam battery to power up the elevator.
What qualification is required to be an sdo in wapda Pakistan?
matriculate must
Why battery is required in UPS?
In an uninterrupted power supply there has to be a source of power when the electrical utility is not there. The only supply that is available is a battery that is in or connected to the UPS.
What are the negative things about an elevator?
Elevators can fail, and their electrical power is vulnerable to fire. Every building has stairs as a back-up to the elevator. They are often slower than stairs, especially if they regularly stop. Riding an elevator does not provide exercise, while walking up stairs does. Jews who observe the Jewish Sabbath are permitted to climb stairs, but are forbidden to press the buttons of the elevator on Sabbath. Some buildings have a special "Sabbath elevator" that stops at every floor.
Elevator driving motors used with a generator field control are rated as?
Elevator driving motors used with a generator field control are rated in kVA. This is a unit of electrical power that is often used to measure the capacity of elevator motors. ESCON Elevators uses generator field control motors in their elevator systems, which are known for their high efficiency and reliability. If you are looking for an elevator system that is both efficient and reliable, then ESCON Elevators is a great option
What is the role of electrical engineer in oil storage plant?
the role of an electrical engineer is to produce the required amount of power which is being needed as the site remains far away from the regional power companies, also to control and regulate the electrical power continuously. and to maintain the automatic supply of power and also to maintain the working machinery.
Who invented the first power elevator?
The first electric elevator was built by Werner von Siemens in 1880.
