(2) press the elevator speed classification: low-speed elevator, medium-speed elevator, high-speed elevators.
(3) according to the traction motors power class: an AC-elevator, Elevator lift, AC frequency conversion.
(4) classification according to the driving mode: a traction motor, hydraulic drive (jackup directly plunger top and side plunger two).
(5) by a worm gear reducer category: gear elevator, worm gear reducer for low-speed, medium-speed elevator. Gearless elevator, traction wheel and brake wheel directly fixed to the axle of the tractor, for high-speed elevators. Using stepless speed control adjustable lift.
(6) classification according to the location of the room: room set at the top of the well road, room located at the bottom of the well road. Wire rope-driven elevator, room generally set at the top of the well road; and top-lift, hydraulic, spiral lift, room General settings at the bottom of the well road.
(7) escalators are handrails, stairs, Rails, pedals, gear belt of incomprehension and comb, panelling, doors, outer doors, apron plate and motor drive mechanism.
(8) automatic sidewalk (a handrail or no armrest) is supporting the pedals, wheel, chain and motor drag horizontal transportation.
Construction site coordination points
1. structural engineering construction coordination
(1) Elevator Hall station on outbound appliance and signal device, with the construction of civil structure for reserved box (carton), buried pipeline, purposeful layer indicator, Hall station integrated indicators, direction indicator the Office station, the Hall call button of elevation, coordinates, box (carton) geometry size should be consistent with the manufacturer requirements.
(2) elevator shaft embedded rail should cooperate with the civil structure of the construction will be requested by the factory presetting.
(3) elevator shaft is the brick structure, using Rails bracket holes, using concrete to build rail bracket, Bandar Seri Begawan, civil construction personnel assist plugging holes.
(4) elevator pit the manufacturer consider need to buffer of fixed seat, you need to set the maintenance of a ladder or with doors of checkpoints, construction by civil professional assistance.
(5) elevator room for a traction device, control cabinet base according to the manufacturer device based process layout, geometric dimensions, position size by civil construction professional assistance.
2. the renovation construction coordination
(1) Elevator engineering construction and architectural decoration combined with:
1) Elevator Hall doors installed on line, certainly Kham, Corbels and ox's leg bracket installation location.
2) installation of elevator door pillar, chute, door set, uses embedded rail fixed; if a brick wall, use the tick wall eye, fixed anchor bolts burried note.
3) where necessary in concrete parts, be approved by the Department to check for hidden project procedures before casting concrete.
4) elevator machine room door and window, walls, floors (floors should be non-slip material), roof waterproofing treatment should be done.
(2) elevator room layout according to the manufacturer equipment from electrical professional construction of lighting and power supply to the control cabinet and the motor terminal box of pipelines.
(3) elevator room to the elevator shaft of the laying of the pipeline or trunking, should be determined by the construction of electrical professionals meet.
(4) elevator car illumination, by construction of electrical professionals meet.
(5) elevator car inner security monitoring lines and equipment, construction by security professionals.
(6) the fire alarm system setting, measuring smoke control fire alarm button, construction by the fire service professionals.
(7) building automation professional need to start and run, etc. of elevator control signals from the lift professional builders and manufacturers with a clear set of control points, is active contacts or passive contact, must not be missed.
(8) Elevator Hall doors and door set of installation, decoration works in advance and civil engineering construction professional, find out the elevator Hall door room decoration what material did the wall surface. Using Dali did the wall stone, the hall door and gate sets in a timely manner according to the marble stone thickness and wall thickness adjustment of mounting dimensions.
Construction site control focus
(1) Elevator engineering construction drawing examination:
1) audit construction drawings by have the legal qualification of design unit design, confirm construction drawings to be used effectively.
2) based on the elevator construction and civil engineering drawings, double-checked elevator specifications, performance parameters, use the open method and wells road Hall door, frame and steel beam position is in line with the civil structure, identify problems in a timely manner.
3) audit logging road pit depth, top station height, room floor load, room location, capacity, power supply, ground protection should be consistent with the elevator construction requirements and design requirements.
4) based on the elevator shaft road, room layout drawings, set aside the hole and the number of embedded iron. Holes including: engine room floor holes, each floor of the hall door button holes and top led box office door, and so the hole. Embedded iron include: lift guide Rails framework and the hall door embedded iron and wells road, piping and wiring embedded iron, etc.
5) based on the layout and install an elevator, will review the findings focus on the list, provide to design units, organization design gives the low-down, mapping problem solution file, to be checked to confirm, and prompt for design changes.
(2) Elevator project construction organization plan audit:
1) key check elevator machine room, cabin, Wells road, Hall station technology and practices, as well as debug test method.
2) Elevator processing orders is the key, but there are two situations:
① construction units in structural design, the elevator order paid enough attention to, the design of the unit under the floor, and out situation selected number of more or less elevator model and wells road, and follow the construction of the building structure. Due to construction unit consider not week, Wells road and elevator car size and larger, the final result is toWell road actual size selection in the elevator.
② building units in structural design, in conjunction with the design and production of manufacturers to determine the elevator model specifications, Wells road geometry, the engine room equipment base, Foyer geometric dimensions, etc., all implemented early in the design, in one step, to facilitate construction.
3) determine the elevator model specifications, quantity, processing cycle, to date, installation date, completion date.
4) check the elevator construction materials, processing orders, workforce scheduling, construction schedule, these plans should be civil total corresponds to the construction schedule to ensure that the overall duration progresses smoothly conclusion.
(3) elevator construction technical quality gives the low-down, should be consistent with the elevator layout and installation diagram, further implementation of the construction process and practices to ensure the construction project by the design requirements, while consistent with existing national standards and norms.
(4) understand the engine room of the building structure beam under load, you should be able to guarantee the equipment of the static load when at rest, but also guarantee the equipment of the dynamic load during exercise.
(5) check the pit depth buffer in the resettlement site can guarantee security of the person in the cabin.
(6) to check the car's top clearance is consistent with existing national standards and norms.
(7) equipment installation, check whether the subject requirement, such as meet design requirements to support Hall station and Kham channel steel, Hall pillars, car rails backplane, on heavy rail backplane, found that structural problems identified, resolved in a timely manner.
(8) Elevator engineering conduct system debugging, responding to the fire alarm control signal, security monitoring, control signals, building automatic control signal all collaborative professional builders, debug run separately, qualified before the completion of the verification.
(9) structure Cap demolition tower crane with temporary, in consultation with civil before the room equipment such as traction motor, control cabinet and other heavy equipment timely cranes in place, into the engine room.
(10) erection lift mast mounting rails should be Derrick construction programme design and audit, compliance requirements before use.
(11) elevator car, guide, entrance hall equipment and components to a construction site, first inventoried, by keeping in place, construction supervision, construction unit, the manufacturer of the Quartet together, confirm the appearance, quantity in line with the packing list and design requirements, the signature. After confirmation, the equipment and parts to the structures, protection plug for use when intact.
