Architectural design specification and the actual

Current "residential building design code for the design of the elevator configuration calculation method, in the real operation cannot objectively reflect the actual use need, cause for examination and approval of architectural design, capacity, the number of elevator configuration, design speed and so on can not meet the actual use need, resulting in a large number of in the overload operation, leaving hidden dangers.

Some developers choose cheaper elevator

Part construction development, such as a property room, such as housing, developers in the bidding in the acquisition of the elevator in order to reduce costs, will generally choose configuration is low, the price is cheap, quality of elevator commonly, also to put into operation after the normal management, maintenance and use of difficult.

Use the unit management issues

Housing decoration neglected greater damage to the elevator, buried hidden trouble. A large number of decoration materials transported by the lift up and down the elevator in overload and heavy load condition, capsules run under non-equilibrium state for a long time to lead to deformation of capsules, guide rail vertical degree change, fixed a loose, etc. Material such as cement, sand, through the car door and floor door gap fell into the elevator shaft, fell to the orbit of lubricating oil, steel wire rope direct mechanical friction on the attachment of operation, significant damage to the elevator safety operation.

The main responsibility implementation does not reach the designated position

Both realty service units and other unit using the elevator, the elevator using the management of safety consciousness, responsibility consciousness and risk consciousness are generally lower, management system is not sound, the measures are not implemented, inadequate security funds.

From the calendar year regulatory situation and accident statistics analysis, the elevator using unit is a key link in the process of elevator safety management, important link, is the need to strengthen the weakest link.

The elevator maintenance quality problems

The lift maintenance market is not standard, due to the maintenance fee fully market-oriented, low-cost business competition between maintenance unit, combined with the maintenance accessories are of variable quality factors, it is also one of the important cause of the quality and safety of the elevator.
