Q:How does the elevator operate

One must first understand the basic structure of the elevator, function, operation and safety protection measures for each elevator, so each new elevator operation need to carefully look at elevator operation manual! 2 each elevator switches in eye-catching position, the first thing to know to control the power box, and stop buttons and effective protection switch, it is helpful for you in the process of operation, have safety emergency measures! 3 each elevator has the control box, it has indicated the direction and floor indicator, if your operation is simple and easy lift, it is not a lot of protection measures, only up to the threshold, sometimes may malfunction, press in operation had better stop, make sure someone wrong operation or accident happen! 4 as for how to increase the security of the original equipment and measures, can reach Ann and suzhou mechanical and electrical technology department contact, they have free professional technical support and solutions!

Q:The safety officer shall be responsible for the work of the construction elevator

(1) the use of dual-use functions of the construction elevator, the installation and removal of the professional personnel issued by the competent department of construction administration shall be undertaken by the professional personnel. The personnel who have passed the training, qualified for the examination and obtained the certificate of the post shall be operated and repaired. (2) the capacity of the concrete base culture cooperation should not be less than 150kPa, the tolerance of 10mm and the drainage facility should be allowed. The distance between the guide bracket of the elevator and the wall of the building should be suitable, and the smoothness should be stable. (3) the lifter is used to control two directions, and the vertical control is 0.05%. Each floor shall have a platform, a passage, a fence and a protective door. No obstacles can be found. (4) the elevator that is installed in a dark place, and the passage shall be illuminated and a floor display lamp and floor number; A closed barrier should be set up in the well. The elevator shall be subject to acceptance by the technical director and the relevant departments, and shall be tested by the crash and shall be used in the rear. (5) in the use of or during the use of the elevators, the manufacturer or designated unit shall conduct the debugging and maintenance and verification. The lifter should undergo a fall test every three months and the fall test should be adjusted when the fall test exceeds 1.2 m. Every time it falls, the receiver should be repaired once.

Q:A lift motor is 7.5 KW, and the frequency converter sends current 4.2 A, which has A heating resistance in the converter, and how the charge is calculated when the lift is full. Or consider the power of the converter and the power of the thermal resistance.

The full load is 7.5 KW. The output current is 4.2 A, is the converter 7.5 KW?

Q:The construction elevator can only go up can't come down what happened

Look at the contactor connectionThe drop contactor does not absorb

Q:How does the construction lift fall without electricity

Pull the manual release (or pedal release) to loosen the electric motor to loosen the brake, the lift will fall, and the speed localizer will die. It's not that professionals don't try "very dangerous"

Q:Are there any good signs in the construction elevator door

It is forbidden to climb, construction lift operation procedure, limited number of passengers, no power cuts

Q:Gear rack driven

The static load of the gear is concentrated in the final gear of the gear.

Q:What about the energy efficiency of the escalator

Variable frequency construction elevator energy saving effect general. Frequency conversion is not energy efficient. The difference between the frequency and the common machine is the smoothness and speed of the operation. Frequency conversion speeds up to 90m / 1 minutes and the average is only 35m / 1 min Frequency conversion when parking is slow down and stop Ordinary is directly stop delay parking and adjustment made door light who bow Angle decyl with brush spring connection will be better. The frequency conversion requires the site voltage to be strictly a little bit looser than the voltage requirement Energy consumption is: according to the elevator drive mechanism for general three transmission two kinds of the elevator are three 11 kw motor, that their energy consumption are 3 x 11 = 33 kw is hours each hanging basket consumes electricity 33 degrees, the actual power consumption will be bigger.

Q:The maximum allowable deviation of the vertical is the vertical degree when the construction elevator is installed

The maximum allowable deviation for the installation of the elevator rail frame is the following: The height of the elevator rail is less than 70 meters, and the vertical deviation should not be greater than one thousandth of the height of the guide frame. 2, the guide frame height is greater than 70 meters is less than or equal to 100 meters, the deviation is less than or equal to 70 mm. 3, the guide frame is larger than 100 meters is less than 150 meters, the deviation is less than or equal to 90 mm. 4, the guide frame is larger than 150 meters is less than or equal to 200 meters. The deviation is less than or equal to 110 mm. The guide frame is greater than 200 meters and the deviation is less than 130 mm.

Q:What is the safety device for construction elevator?

Fence threshold position, threshold position, both inside and outside ladder ladder cage cage up and down limit, limit switch, for safety device, weight limiter and ladder to the top of cage outside the door stop, on the abrupt stop switch. The highest point is a toothless standard day. There are elevators and ultra high sensing switches.
