Prominent feature of the whole staircase First, 80% of the whole staircase, after commissioning the factory fully assembled components, including electrical parts, using connectors, saving the installation period. Second, column fine blanking, cold-formed steel to replace a large section of angle iron, bolted to the transverse ribs, longitudinal ribs, brace fixed to the column on other components. (Effect: to prevent the landing door by subsidence caused by plate loose and slide deformation and other defects; improve the overall framework of strength). Third, rail car filled with cold-drawn materials, T-rail, on top of layout, each car with the re-run in a separate track, to ensure the car on the smooth running of. Fourth, 100kg-500kg lift debris with frame structure can be more suitable for users without wells, and small footprint. Fifth, electrical and mechanical joint locks (optional) Door lock switch hook and touch one, so that at least 5mm above the lock engaged, the contact can be connected. Switch closed and the simultaneous detection of door locks shackle meshing state, leveling automatically lock, automatic door locking. Realize the true sense of the requirements of mechatronic locks, door locks, mechanical locks off the hook at the same time, disconnect the electrical section also improve the efficiency and safety of the elevator performance. Sixth, electromagnetic door knife (optional) Electromagnetic door lock knife is to achieve a key component of mechanical and electrical integration, the product moves under the car running state, the lift during operation, electromagnetic door knife always maintained contraction, through an intermediate layer, and always from the landing door locks touch round, to eliminate the car through the middle layer, the landing door may be open to abuse, eliminating the security risks. Seven-in-one car Car wall on the use of all-inclusive, integrated car designed under the beam can be achieved by the end of compression car, car top tensile strengths. Eight, the door system uses a modular design, installation and replace them more convenient. Nine, door systems key components of fine blanking die, aluminum alloy to improve the accuracy of the installation of valve clearance. Ten, the door hanging round with anti-tank unit out of one design, the complete elimination of the door rope off phenomenon. XI, all hidden in the slide doors inside rope, maintenance or malfunction occurs to prevent scratching the door to justice. Second, the car door with a stop device and double-contact detection switch, preventing the elevator car door opened during the operation of the drawbacks. XIII smooth surface towards the car door car, open the door to prevent scratching during the small items. Fourth, offices, car door hanging open the door to play board and pallet limit function, even if the door rope breaking, the doors remain in the chute, to prevent the accident, the door crashed. Fifth, doors additional damping pads, effectively reduce the noise when closed. Sixteen, door slide, door slide and door stiffeners adopts aluminum alloy structure. Seventeen, door handle stainless steel handle.
