(1) this series of products are composed of several detachable parts, which are mainly composed of four parts: lifting mechanism, operating mechanism, control device and braking device. The use, maintenance and inspection are very convenient and the overhaul cycle can be shortened;
(2) the motor adopts YZD series three-phase asynchronous motor with tapered rotor, with protection grade of IP44 and insulation grade of H. the conical brake of motor is used as support brake; the hoisting mechanism is additionally added with safety brake;
(3) high temperature heat insulation protection function is set under the electric hoist to effectively avoid direct thermal radiation;
(4) steel core wire rope is adopted for steel wire rope, which has high temperature resistance characteristics;
(5) the hoisting mechanism is equipped with an overload device. When the lifting capacity reaches 95% of the rated lifting capacity, the overload device will send an alarm signal. When the lifting capacity reaches 105% of the rated lifting capacity, the lifting control circuit will be disconnected, the lifting contactor will be released, and the motor will stop rotating after power failure;
(6) the hoisting mechanism realizes the double protection of ascending limit, the grade of protection is the fire break limit protection, and the second level protection is the off control protection;
(7) Chint contactor is used for electrical components of control box, and the protection grade of control box is IP44;
(8) the reducer adopts standard module cylindrical gear, which is convenient for maintenance.
(9) the parts are universal and interchangeable.
