gear and rack drive construction lifter

Gear rack drive type (SCD) construction lifter is of single column double cage,equipped with the

weight of the wall construction lifter.The structure of the use of single column double condole cage

to save material,set of heavy block with a certain energy-saving effect and the hoisting cage falling

have certain protective effect.Of weight of this model,no fall protection devices,hoisting cage on

only a limited (super) speed device (lift regular high and low,equal fault protection exception).Hang

the power plant is located in the cage,driven by gear and rack is big,big noise,vibration and wear

fast and power cable to the disadvantages of coarse,not conducive to speed up,etc.2,gantry Gantry is double columns,single hanging basket,attached to the wall type,hoist single rope forced traction increase,its material,energy consumption is large,broken rope rotor cutting machine protection device generally adopted into type,using trigger broken rope protection device,such as the spring trigger reliability is poorer,less braking safety.

Do not conform to the compulsory industry standard-"building construction safety inspection standards" (JGJ59-99) on the terms of the requirements,often appear machine crash accident,the country being eliminated,but because of its low price,installation is convenient,easily accepted by the user.Aluminum alloy type Aluminum alloy lift high strength high quality aluminum alloy materials,due to the high intensity profile,minimal deflection and swinging the lifting platform.New design of a new generation of elevator has beautiful shape,small volume,light weight,balance,and the advantages of safe and reliable,the appearance of the light,it can be in tiny space in the highest lifting ability into full play.Make a single aerial work becomes easy.Widely used in factories,hotels,restaurants,railway permanent magnet motors for salestations,airports,theaters,exhibition halls and other places,is to maintain machine,paint decoration,exchanging the lamps and lanterns,electrical appliances,such as cleaning and maintenance purposes best partners.

Crank arm type work high lift car can overhanging operation,across some obstacles or in a lift can be carried out more work;Platform capacity big,for two or more people work at the same time and can carry a certain device;Lift platform mobility,convenient transfer site;Beautiful shape,suitable for indoor and outdoor operation and storage.Applicable to the station,wharf,shopping malls,sports venues,residential property,factories workshop and so on a wide range of operation.A,innovation,developed the SSD model of single column double cage hoist 1,the reference design (1) reference attached SCD construction lifter of single column double cage,SCD construction lifter column using an attached lever to transition frame fixed to the wall attachment methods,SSD construction lifter column by the attached bar fixed on the wall,eliminating the transition.(2) using the elevator using wedge rotor and stator brake and traction elevator design,using wire rope traction elevator and wedge brake.Trigger such as wedge brake using non-traditional spring,because spring rust will lose elasticity,so new reliable trigger system is designed.

2,innovation protection design Use unconventional design way and the thinking of innovation,make the products not only meet the national standard,also higher than the national standard.(1) the SSD type hoist crane cage and the weight of two root traction rope automatic tension balancing device was designed and implemented two traction rope hoisting cage and the heavy block,ascending simultaneously than save a few root elevator traction on the rope.(2) the tractive rope for wear in a single week,the week wear,local extrusion caused by internal wear and broken wire broken stocks,beyond the amount of extension,the rope break before they can be protected.To avoid the wire rope breaking point on both sides of the rope body disorderly fall from the sky,not cause safety accidents and subsequent damage.(3) the hoisting cage and the weight between the number of root traction rope after fracture,and there was a hoisting cage and the heavy two-way for protection.(4) the hoisting cage and the weight of any root traction rope fracture,all have the corresponding fault line protection.(5) when the rise and fall of the normal work of the hoisting cage or power failure,the hoisting cage stops at any level,in addition to the normal brake motor function,the cage stops running,has overcome inertia and tractive rope hanging cage elastic effect

caused by the lift cage string move up and down the electromechanical integrated device and stop

device,dock automatically stop layer and protection.(6) when the motor brake failure or coupling

damage caused by traction wheel out of control,and the two root traction rope did not break,the heavy

piece or hanging cage on one side of the slide speed falls down,have to lift heavy blocks and cage

two-way overspeed protection.The protection device of speed sensing device for mechanical and

electrical integration,overcome the elevator mechanical speed limiter one-way speed

sensing,unfavorable outdoor installation.
