| Message: | Model: GRFH10GRFH10 Hydraulic freight elevator has the multiple lifting modes. It is applicable for the elevators with different traveling heights and capacity so as to satisfy various requirements from customers.Compared with traction elevator, hydraulic elevator has the following obvious advantages:1. Flexible setting of the machine room positionTop machine room is not needed. A machine room can be flexibly set within 10 meters range near the shaft which more comply with the individual design requirements of the constructions.2. Saving space and energy consumption, reducing the cost.Counterweight device is not needed, which increases the utilization rate of the hoistway and greatly saves the construction space and costs. Meanwhile, when the elevator is going downwards, depending upon the work done by the cabin's own weight, no electricity is consumed.3. The highest safety and reliabilityApart from all the safety protection devices of the traction elevators, we additionally add the multiple hydraulic circuit protection systems such as safety valve, limited speed disconnecting valve etc.4. The products are of the compact structure, low fault rate, easy for the daily maintenanceStandard FunctionTravel FunctionCollective selective controllCollective selective controlling without the presence of operatorDrive driveWe fulfill the elevator travel through controlling the liquid flow in the electronic valve.VVVF Door operatorMotor rotating speed can be precisely adjusted to get the more gentle and sensitive door machine start/stop.Reopen 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 ......url:http://www.sicherchinaelevators.com |
