Hoisting mechanism is configured with two supporting brakes and a safety brake . The first stage is a conical rotor brake motors that work magnetic pull brake , reducer enter the second stage of the installation head dry friction brake to prevent the first stage of brake failure and will continue to make normal load lifting system action . Safety brake is safe brake emergency braking device installed on the reel assembly, under the agency fails to prevent the transmission can be damaged emergency safety electric trike emergency brake drum braked to prevent accidents caused by falling loads .
1 , the upper limit position of the secondary limit device . The first is the conventional electric hoist , lower travel stop limit , the second is heavy vertical limit .
2, the host heat radiation protection, under the sub- ah roll shell fitted with electric hoist machine installed insulation panels, sheet metal folder filled with two high temperature asbestos material to Folding electric bikes isolate the radiation temperature of molten metal .
3 , lifting the motor and run the motor using H -class insulation class and built- in lifting motor winding overheating protection device.
4 , rope using 6 × 37S + IWR-GB8918-2006 uses high-strength high temperature resistant wire rope is important .
5, the electrical control device to set the zero -voltage protection , voltage protection , phase protection boxes overcurrent protection , control equipment cables using ZR +-YCP group fired heavy rubber cables.
6, the control method using remote control , also can be centrally controlled .
