Product quality is the lifeblood of enterprise development. Over the years, BLT has been taking the product quality inspection as a top priority of production chain. So far, a perfect, orderly and well-targeted product inspection system has formed. And the inspection equipments have achieved the world-class level.
Strict control of each inspection procedure makes the BLT elevator products in a leading position in quality, performance, conformability and stability among the similar products.
  • Elevator test tower
    Elevator test tower

    First-class elevator test tower, doing laboratory tests for 11 shafts, running around the clock. All BLT products have to be tested fully in the test tower before finalizing the design. Analyze test data and improve the products so that all aspects of performance indexes can achieve perfection.

  • Door operator test
    Door operator test

    Three million trouble-free continuous fatigue tests, uninterrupted test for door operator's running performance, noise and reliability etc. fully guarantee the performance and quality of door operator products.

  • Overall escalator test
    Overall escalator test

    It is required that every escalator and passenger conveyor should be installed on the overall test system platform within 48 hours before leaving the factory. Conduct comprehensive and strict test for indexes of step, tread, handrail running and all kinds of safety protection devices. During the test, operating condition and laying method of escalator should be exactly the same as normal use. All technical performance indexes of escalator and passenger conveyor tested have to completely meet the enterprise standard requirements.

  • Test of main components of elevator
    Test of main components of elevator

    The main components of elevator, in strict accordance with ISO9000 international quality management system, shall be conducted simulation test by advanced professional experimental devices such as control cabinet test platform, product inspection platform, high and low temperature experimental cabinet and vibration experimental platform etc., which can ensure the quality and performance of the products.

  • Traction machine platform test
    Traction machine platform test

    Before leaving factory, every permanent magnet synchronous traction machine must pass the test of empty-load in test platform, gearless loading running-in and stall experiment to guarantee that all performance parameters such as vibration, noise and temperature rise of traction machine meet standards. Conduct the test of withstand voltage, interturn pressure-resistant, insulation resistance and DC resistance for the coil of permanent magnet synchronous traction machine and frequency conversion motor by coil test platform.
