If the elevator is within the warranty period, it should be repaired at the expense of the development company。Of course, if the warranty period has passed, and the elevator is naturally damaged, it should be paid by the property company, and the special maintenance fund application for the house is directly transferred to the property company。In addition, you can also choose to repair after the cost is in place。

Changsha elevator maintenanceWhat are the steps of maintenance？
1、Changsha elevator maintenanceAfter the maintenance personnel arrive at the scene, they should ask the elevator management personnel and the elevator driver about the operation and failure of the elevator, and make records。
2, maintenance personnel in the elevator maintenance, overhaul, should first hang the "elevator maintenance, overhaul" sign in front of the hall of each floor。
3, maintenance personnel in the elevator machine room inspection or refueling, should first cut off the main power supply of the elevator line, confirm that no power can be checked and refueling。
4. Check the contactor contacts and wiring on the main circuit of the control panel, and tighten the terminals of each main circuit。Check the relays in the control panel cabinet, repair the ablative contacts or replace the relays。
5. Check all the resistors and capacitors of the control panel cabinet, whether there is virtual welding, welding off, resistance ring breakage, resistance wire breakage, etc., replace the resistor, resistance ring and capacitor, and re-solder。
6. Check the fuse holder and fuse wire on the control panel, rotate and replace the fuse wire to make it conform to the standardization。Check and adjust the mechanical interlocking of contactors and relays on the control panel cabinet。
7. Check and adjust the terminals on the control panel cabinet, and do a good job of cleaning。Check the selenium rectifier, silicon rectifier, and do a good job of cleaning。

Check and maintain the tractor
1. Check the oil quality, oil level and the meshing of worm gear and worm gear, and change the oil of worm gear box once a year。(Cursor: according to product technical requirements)
2. Check the oil quality and oil level of the sliding bearings (copper bushing) at the front and rear ends of the tractor motor, and clean and change the oil of the sliding bearings at the front and rear ends once a year。
3. "Lithium grease" injected on the propeller shaft of the tractor (at least once a year)。
4. Rewind the wheel of the traction machine, inject lithium grease across the bridge wheel (once a month)。

Hunan ElevatorWhat is security really like？
1. Take the vertical elevator as an example。Light curtains, door force limits, speed limiters, safety clamps, upper and lower limits, forced speed changes, brakes, etc。All belong to the elevator safety protection, and most of the series in the safety loop, once the switch action, will make the elevator stop, to ensure the safety of passengers。Daily maintenance plays a vital role in the early detection and elimination of elevator problems。For problems or possible problems to be eliminated as soon as possible, not to short-circuit the safety switch will greatly reduce the occurrence of accidents。
2, most of the vertical ladder safety accidents generally have the following categories: fall injury。Short-connecting the hall door, or the hall door slide is missing, the brake braking force is insufficient, the speed limiter safety clamp cannot be linked, the safety clamp wedge cannot synchronize, and the buffer failure will cause 。Shear damage。The car door is short connected at the same time, or the car door is short connected, and the door lock cannot be effectively locked。
3, at present, the elevator inspection has a mandatory annual elevator inspection by the local security department, and the local special equipment testing institute conducts equipment testing, and issues the elevator inspection report after passing the test。Each company also has a variety of internal security checks, irregular, personal think that the annual inspection of the institute is strict。
4, for the individual to take the ride, in most cases, can not know whether the elevator has a safety hazard, many people in the ride, with noise, shaking and other comfort to judge the quality of the elevator, is not rigorous。As an elevator maintainer, I don't even know if my elevator is free of any safety hazards。Do not easily enter the elevator machine room maintained by others, do not check the line at will, personally think that is to maintain the staff 朂 basic professional ethics。

5, compared with the elevator, the escalator is more prone to accidents, the use of escalators should be more careful, look at the pedal on, soon to the next, maintain a stable standing handrail belt, ladies please pay attention to long hair and skirt。Children pay attention to rubber foam shoes。For strollers, please use the elevator。Pick up the pet。The elevator is not a playground. Take care of the kids around you。
