Smooth reliable action , does not slip , shoe contact surface not less than 70 %. 2.3.2 When the brake is not opened , the shoe should hold together tightly , disc wheel disc should be able to move his hand . 2.3.3 brake is open, the gap should be the same on both sides , both sides of the average value of each of its four corners of the gap should not exceed 0.7mm. 2.3.4 . Brake opening and closing should be flexible and comfortable , the coil temperature does not exceed 60 ℃. 2 control cabinet, the electrical components inside 2.4.1 should work properly , the instrument accuracy . 2.4.2 without fever phenomenon , the contact point contact strict no adhesion burning phenomenon ; 2.4.3 Anti switch cabinet no oil no dust . 2.5 speed systems, wheel speed 2.5.1 : clean appearance , flexible movement , no significant month RBI , oil unobstructed , jaw rope at no foreign oil, wheel slots no abnormal wear. 3.2 up sheaves and safety gear unit : clean appearance , oil smooth , smooth rotation, tensioner felt refueling, each flexible safety gear linkage , jaw and face the side rail gap between 2-3mm . 4 layer selection system rotation and layer selection is part of the slide clean and sufficient oil , clean the contacts , the pressure is appropriate. 5 rooms, car door systems 2.7.1 hall , after the car door properly closed , door locks should be able to turn on the network ; minimum length of engagement of the locking element is 7mm, this time outside the hall doors should not be able to hand clawed . 2.7.2 Security touch panels, photovoltaic devices function reliably . 2.7.3 landing door , car door , rotating parts and slide : rotating parts cleaning , turn freely , filling lubricating on glideslope debris removal , the chute refueling, Diaomen wheel, door slider wear timely replacement . 2.7.4 Switch door mechanism : the door switch total程清洁, activities and rotating parts clean fuel, proper belt tension , non-skid, door opener remove carbon deposits , cleaning . 6 floor display system , the election outbound systems. 2.8.1 . Indicate normal function of each component , buttons move freely without jamming . 2.8.2 lighting display properly , clean and dust free . 2.9 hoistway systems 2.9.1 . Car, counterweight guide shoes clearance uniform, boots lining no serious wear and tear. 2.9.2 Oil boxes, oil brush without defects, track -oiled . 2.9.3 . Rope tension is uniform and no broken stocks. 2.10 Health , iron gate to the machine room of the corridor ; . Room ; jiaoding ; bottomless pit and other parts should be kept clean and free of garbage , remove oil and dirt .

Months warranty
Week month maintenance is based mainly on the maintenance of the lift member for cleaning , lubrication , inspection, in particular the inspection of the safety device . 3.1 reducer, 3.1.1 should be no abnormal noise reducer , remove surface dust grease . 3.1.2 To Rolling worm oil refueling, check the coupling without injury . 3.1.3 Check each rope sheave grooves worn are consistent traction wheel bolts fastening the various parts . 3.2 motors , generators, 3.2.1 clears its internal and external dust and oil. 3.2.2 . Velocimetry system is working properly , the transmission system without damage. 3.3 lubrication brake 3.3.1. Checking solenoid between the heart and the copper sleeve . 3.3.2 fastening the connecting bolts. 3.3.3 coil temperature does not exceed 60 ℃. 3.4 speed systems 3.4.1 . Clear clip rope jaw foreign body , oil . 3.4.2 Rotary pin site refueling. 3.4.3 Check the wheels and wheel speed limiter tension pulley groove , with or without abnormal wear . 3.4.4 Check the tensioning device and electrical switches and movement is normal . 3.5 The control cabinet , excitation cabinet . 3.5.1 Check Calvary electrical components, instrumentation, for insensitive and should adjust the replacement of damaged components . 3.5.2 Check the contactor, relay contacts ablation circumstances, such as serious irregularities should be repaired or replaced contacts. 3.5.3 Check the mechanical interlocking device , the operation should be adjusted unreliable . 3.6 rope, 3.6.1 . Checked rope corrosion and wear, rope locking bolts should , cotter pins are available. 3.6.2 . Rope tension should be uniform. 3.7 Office of the car door system clears all parts of dirt , oil , check the hanger wheel, door guide bearings , oil painting . 3.8 System 3.8.1 Clear selected layer of dust and grease all parts , electrical adjustment layer selection action gap or accuracy. 3.8.2 of steel wheels and axles up rope refueling , active carriage rails add oil. 3.9 Rail : The rail automatic lubricating device , should bear the machinery lubricants . 3.10 safety device , 3.10.1 check the site : phase failure protection , overspeed protection device, mechanical interlock device , the Office of the car door electromechanical interlock , emergency stop switch, switch repair inspection , security windows , limit , limit switch . 3.10.2 Each safety devices should be flexible and reliable, no jamming , remove grease all safety devices . 3.11 bottomless pit, pit cleaning debris , dust clears buffer and the parts to keep the pit dry.

Half year warranty
Half a month , mainly in the maintenance and maintenance on the basis of examination of the key parts of the elevator adjustment , maintenance . 4.1 motors , generators, 4.1.1 added bearing lubricants. 4.1.2 Check the carbon brush holder repair , cleaning, direction finder . 4.2 4.2.1 traction rope tension adjustment with less than 5% from the mean . 4.2.2 rope surface oil too , should be cleared . 4.2.3 Checking and rope rope rope combination plates are intact . 4.2.4 broken wire rope inspection and corrosion conditions 4.3.1 4.3 shoe cleaning automatic lubricating device , at the filling metal bearing grease . 4.3.2 fastening bolts guide shoes , boots and guide rails fixed positive gap should be specified. 4.3.3 Check the sliding guide shoe pad wear than the original thickness of 1 /4 should be replaced .
