Clean the counterweight device and check whether the screws of each

Passenger lifts Manufacturers

Clean the dust of each Passenger lifts Manufacturers, the rollers of each switch are flexible, and the contacts are in good contact. (3) The wiring of each switch is not loosened or soldered. (4) The switches are firmly fixed, and the positions of the switches and the touch iron are relatively accurate. When the car sill crosses the upper sill 50~100mm (Japanese elevator 20~150mm), the limit switch will act; when the car sill exceeds the end station sill (Japanese elevator hydraulic buffer elevator is 250\) , The spring buffer elevator is 40050mm)

The limit switch should act. 2.3.3 Counterweight device (1) Clean the counterweight device and check whether the screws of each part are loose. (2) Whether the counterweight is compressed or not, adjust the bottom of the counterweight to see if the fixing screws of the iron block are tightened. 2.3.4 Leading rope, speed limit rope, balance rope (1)

Check the wear, breakage, twist, rust, etc. of the wire rope every 1m in the slow car. Change the rope if one of the following conditions is found. \; The breakage is uniform, with 4 or less breaks in one lay length; b) The rope diameter is reduced to less than 90% of the original rope diameter; c)

When the breaks are concentrated in one or two strands, in the most severely damaged section, one twist 4 or less broken wires in the lay length; d) Due to severe rust, individual wires in the strand are excessively worn, and 2 or less broken wires in one lay length. (2) Check whether the tightness of the lead rope is consistent, usually by hand or spring balance measurement method. When measuring with a spring scale, the tension difference should be %. (3) Check whether the rope head combination screw and split pin are off. (4) Check the contact between the rope and the wheel groove.

The length of the traction rope meets the requirements

Passenger elevator lift

When the wear depth of each groove differs by 1/10 of the rope diameter, or the gap between the traction rope and the groove bottom is less than 1mm, the rope wheel should be removed for repair or replacement. (5) Check the length of traction rope, speed limit rope and balance rope. The elevator stops at the leveling position of the upper station, from the bottom of the counterweight to the upper end of the hydraulic buffer 150mm, to the upper end of the spring buffer 200~350mm, and the rope should be cut if the size is below the lower limit.

After the length of the traction rope meets the requirements, measure the length of the balance rope. The tension wheel frame of the balance rope device should be 200mm from the ground channel steel. If it is lower than this value, the rope should be cut. The balance chain generally does not extend.

If it does extend, check whether the joints of each chain link and the fixing bolts at both ends are tight. Check whether the distance between the bottom of the speed-limiting rope tensioning device and the pit ground meets the requirements and whether the iron arm is balanced. The distance requirements: domestic ladder, high-speed ladder 750\; fast ladder 550\;50mm; low-speed ladder 400\;50mm; Japanese ladder, 200\50mm. The rope should be cut below the above lower limit. 2.3.5 Guide rails and brackets (1)

Check whether the Passenger elevator lift of the car and counterweight guide rail brackets are loose, whether they are unwelded and whether the civil engineering connections are loose. (2) Clean the working surface of each guide rail and add oil appropriately. Check whether the rail connecting plate bolts are loose and whether the rail is deformed. 2.3.6 Follow the line (1) Check whether there are any objects in the hoistway that are in contact with the cable, whether the cable sheath is cracked during operation, and whether the cable is twisted. (2)

This work should be carried out by the special subordinates

Freight Elevator

in some places, the inspection agency will organize non-supervisory inspectors to conduct comprehensive acceptance; in some places, the local quality supervision administrative department will take the lead.

Check and accept with relevant departments. Because there is no uniform regulation, it often causes conflicts between inspection agencies and other departments. In response to the above-mentioned problems, the author believes that: 1. The elevator installation supervision and inspection regulations are statutory inspections implemented by the government to ensure public safety.

They belong to the administrative licensing items approved by the State Council and implemented in accordance with the law. This work should be carried out by the special subordinates of the local quality supervision departments. Implemented by the Equipment Supervision and Inspection Institute.

Whether it is a construction supervision company or another equipment supervision company, or any supervision required by a consulting service organization, it is a corporate action. Moreover, the state has clearly stipulated the implementation agency for elevator installation supervision and inspection, and other intermediary agencies should no longer raise the issue of elevator installation supervision.

Add unnecessary Freight Elevator burden to elevator users. Even if the elevator user agrees to the intermediary agency to participate in the supervision, the conclusion of the final installation quality of the elevator should still be based on the conclusion of the supervision inspection report issued by the legal inspection agency.

The staff should carry relevant appliances and take certain measures

Passenger elevator lift

 if you want to cough or sneeze, you must cover your mouth and nose with a tissue (handkerchief). If you don’t have a tissue, cover it with the palm of your hand. People; farting must be very impolite and embarrassing at this time, so you need to try to restrain yourself. Try to avoid talking.

Because the elevator space is small, especially when crowded, the distance between people is less than the minimum communication distance. Passengers should remain silent as much as possible, and they can nod their heads or say hello; if they must speak, they should be whispered and cut. Don't make a loud noise, lest you appear to be lacking in education; staring at others is also considered impolite.

Push the buttons in order. Press the button of the floor you want to go to in turn. If you are too far away from the button or the elevator is crowded, please try to let passengers close to the button help press the floor button, with polite words such as ellip; several floors', 'thank you', etc. ; If someone walks to the elevator entrance quickly, please press the 'open door' button in time to wait for others to come in; close the door as soon as you get on the elevator, and you don’t want to wait for latecomers. This behavior is very poorly cultivated; also don’t wait for acquaintances , Regardless of other passengers, let the elevator stop at a certain floor for a long time.

The staff should carry relevant appliances and take certain protective measures when repairing the elevator. ⑴. You must wear work clothes, work shoes, and work caps when you work; ⑵. When using electric welding, gas welding, or blowtorch, use a safety mask; ⑶. When cutting the wire rope or climbing high, you must wear a safety belt, and the real point of the safety belt must be firm and not movable or broken; ⑷.

For example, Passenger elevator lift and safety helmets must be worn when hoisting the car; ⑸. If the elevator needs to be powered off for maintenance, the power switch must be hung up with a sign of 'No closing'; ⑹. When two people work together, the passwords must be the same, and they must be repeated with each other.

 

Fast elevators are generally divided into single-layer running speed

home lift elevators

Forced deceleration limit for home lift elevators up and down Elevators with speeds below 1 m/s are generally equipped with an upward forced deceleration limit and a downward forced deceleration limit. The installation position should be equal to (or slightly less than) the deceleration distance of the elevator. Elevators with speeds above 1.5 m/s are generally equipped with two upward forced deceleration limits and two downward forced deceleration limits.

Because fast elevators are generally divided into single-layer running speed and multi-layer running speed, the deceleration distance is different at different speeds, so it is divided into multi-layer running deceleration limit and single-layer running deceleration limit. Function 1: When the elevator reaches the end station, the elevator is forced to enter deceleration operation. Function 2: At present, many elevators use the forced deceleration limit as the forced correction point of the elevator floor position. Trouble phenomenon 1: Elevator express train cannot run upward, but slow train can.

Reason: It may be that the upward forced deceleration limit is broken and in a disconnected state. Trouble phenomenon 2: The elevator express train cannot run downwards, but the slow train can. Reason: It may be that the upward forced deceleration limit is broken and in a disconnected state. Fault phenomenon 3:

The elevator is in a fault state, and the program is protected. The fault code may be displayed as a speed change switch fault. Reason: It may be that the upward or downward forced deceleration limit is broken. Because the forced deceleration limit is very important in elevator safety, many elevator programs are designed to have a detection function for this limit. If the limit is detected to be broken, the program will be protected. The elevator is in a 'dead' state. 

The rated speed of the elevator is generally 0.63

Elevator Handrails Manufacturers

1) The main parameters of the elevator The main parameters of the elevator refer to the rated load and rated speed. a) Rated load capacity (unit: kg): The load capacity of elevators mainly includes 320, 400, 630, 800, 1000, 1250, 1600, 2000, 2500kg, etc. b) Rated speed (unit: m/s):

The rated speed of the elevator is generally 0.63, 1.00, 1.60, 2.50m/s, etc. 2) The basic specifications of elevators The basic specifications of elevators include the following seven parameters: a) Use of elevators: refers to passenger elevators, freight elevators, bed elevators, etc. b) Rated load: refers to the elevator load specified by manufacturing and design. The unit is kg. It is the main parameter of the elevator. c) Rated speed: refers to the elevator operating speed specified by manufacturing and design, in m/s. It is the main parameter of the elevator. d)

Drag mode: refers to the type of power used by the elevator. It can be divided into AC electric drive, DC electric drive, hydraulic drive and so on. e) Control method: Refers to the method of controlling the operation of the elevator, namely manual control, button control, signal control, collective control, parallel control, elevator group control, etc. f) Car size: Refers to the inner and outer dimensions of the car, expressed in depth times; width. The internal dimensions are determined by the ladder type and the rated load, and the external dimensions are related to the design of the hoistway. g)

Door Elevator Handrails Manufacturers: refers to the structure type of elevator door. It can be divided into middle-parting doors, side-opening doors, direct-parting doors, etc. According to the above seven parameters, the service object, transport capacity, work performance and requirements of the hoistway machine room of an elevator can be basically determined. The combination of these contents is also called the elevator series type spectrum.
