Traction Freight Elevator

Model: GRFGRF Series freight elevators employing the fully PC controlling technology, AC variable frequency and variable voltage VVVF, has no t only the outstanding performance in energy saving and precision of leveling and highly effective load capacity, but also take the user's requirements into full consideration when designing. As a result, the performance /price ratio of these elevators is extremely high and the elevators can be used in vertical transportation occasion such as factories, transportation centers, warehouses and vehicles, vertical transportationStandard FunctionTravel FunctionCollective selective controllCollective selective controlling without the presence of operatorReopen with hall callIn the door shutting process,press reopen with hall call button can restart the doorCar stops and door openThe lift decelerates and levels,the door only opens after the lift comes to a complete stopAutomactic returning to the base stationWhen the traffic flow is low, elevator without receiving commanding signals will automatically return to the base floor and standby with the door closedDirectly runningUnder the operator's control, after the direct running button is pressed, the elevator only runs directly according to the directives from inside the car and does not respond to any calls from outside.Automatic pass without stopWhen the car is crowded with the passenger or the load is close to preset value,the car will automatically pass the calling landing in order to keep maimum travel efficiencySafety functionRepeated door closingIf the lift can not close the door due to certain obstacle or interference, the lift will reopen or re-shut the door until sundries results in more safe and reliable lift travelPower on re-levelingA power failure might cause the elevator to stop between two floors. However, upon recovery of the power, the car automatically moves to the nearest leveling floor.Overload holding stopWhen the car is overload,the buzzer rings and stops the lift in the same floorAnti-stall timer protectionThe lift stops operation due to slippery traction wire ropeStart protection controlIf the lift does not leave door zone within the designated time after it gets started,it will stop the operationInspection operationWhen the lift enters into inspection operation,the car travels at inching runningUp/down over-run and final limit protectionThe device can effectively prevent from the lifts surging to the top or knocking the bottom when it is out of control.It results in more safe and reliable lift travelDown over-speed protection deviceWhen the lift downs 1.2 times higher than the rated speed, this device will automatically cut off control mains,stop the motor running so as to stop lift down at over-speed. If the lift continues to down at over-speed, and the speed is 1.4 times higher than rated speed, safety tongs act to force the lift stop in order to ensure the safetyUpward over-speed protection deviceWhen the lift up speed is 1.2 times higher than rated speed, the device will automatically decelerate or brake the liftPhotocell protectionIn the door open and close period, infrared light that covers the whole door height is used to probe the door protection device of both the passengers and objects.Emergency functionEmergency car lightingEmergency car lighting automatically activated once power failureFive way intercomCommunication amid car,car top,lift machine room,well pit and rescue duty room through walkie-talkieFire emergency returnIf you start key switch in main landing or monitor screen,all the callings will be cancelled.The lift directly and immediately drives to the designated rescue landing and automatically opens the doorMan-machine interfaceMicro-touch button for car call and hall callNovel micro-touch button is used for operation panel command button in the car and landing calling buttonFloor and direction indicatior inside carThe car shows the lift floor location and current travel directionFloor and direction indicator in hallThe landing shows the lift floor location and current travel directionEnergy-saving functionCar ventilation, light automatic shut offIf there is no calling or command signal within the stipulated time, the car fan and lighting will be automatically closed in order to save the energyRemote shut-offThe lift can be called to main landing(after finishing the service) through the key switch and automatically exists the serviceOptional FunctionTravel FunctionOperation control at stationsThrough turning the key switch insatalled on a specific floor( optional), the elevator can e arranged to stop service for a certain floors.Door open time extendingPress special button in the car, the lift door keeps open for certain period of timeBellIn emergency conditions,if bell button above car operation panel is continuously pressed,electric bell rings on top of the carfreight elevator parameterTypeCapacityRated SpeedCar sizeDoor SizeHoistway sizeOverheadPit DepthMachine room sizeMax Traveling height(Kg)(m/s)WxD(mm)2P side opening2P center openingWxD(mm)(mm)(mm)WxDxH(mm)(m)Machine room10000.51300x17501300x2200/2400x2400450015003300x3300x290030Machine room20000.5/1.01500x27001500x2200/2800x3350450015003500x3700x290030Mac hine room30000.252000x2900/2000x22003400x3550460017004000x3900x290030Machin e room50000.252400x3600/2400x24004000x4250480017004000x4250x330015Machin e roomless10000.51450x16501100x2200/2350x210045001700/30Machine roomless20000.51500x2700/1500x22002800x335045001700/30Machine roomless20000.5/1.01500x2700/1500x22002800x335048001800/30 url: http://www.sicherchinaelevators.com
