Specifications: JG chain-device series 1)Double limit switch device- Avoid impacting the top limit ,carry out soft stop. Very convenient in adjusting location ,and the error is no more than 1.50CM with its compound driving structure 2) Chain-driving- High gear train efficiency .With national patent on its anti-broken chain device organ ,secure but substantial. The organ inside will be locked within a second in case of sudden disconnection of electromotor driving chain occurs. 3)Brake device- Adopt strengthened fibre .High frictionfactor ,low noise,low abrasion and stable braking performance under high speed running and heavy load. 4)Controlling part Adopt alternating current contactor. Good in energy saving ,no shake occurs at the contact terminal, without magnetic leakage, without temperature increment, noise-free and maintenance-free .Suitable for frequent start-up and control.
