LVF is an advanced technology by variable frequency control, with its motor controlled by PLC which realized the stepless speed control. The brake adopts YWZ3B series electric hydraulic pusher brake. The speed reducer is composed of crown and cone gear with planetary gear. LVF variable frequency hoisting mechanism has the advantage of high working efficiency, long service life, low maintenance cost, comfortable operation and so on.
