Metallurgical Electric Hoist is lifting equipment used in metallurgy environment for lifting and handling molten metal, it is improved product on the basis of CD, MD electric hoist, with dual brake, double spacing, insulation boards and other varieties of protections, working level is M6. It is safe, reliable, parts with high degree of universality and compact structure.
Dongqi Crane is professional material handling equipment manufacturer and servicer with largest production in global. Provide you with overhead crane, gantry crane, electric hoist, etc. of safe, reliable and efficient crane solutions and services.
Metallurgical Electric Hoist Features
Metallurgical Electric Hoist mainly consists of lifting mechanism, traveling mechanism, electrical control system, and the second braking device. With dual brake, double spacing, insulation boards and other varieties of protections.
Using YZD series conical rotor motor, protection class IP54, motor insulation class H, the motor comes with cone brake, hoisting mechanism with other safety brake as its own.
Double spacing protection
Metallurgical Electric Hoist lifting mechanism is double limit protection, the first stage protection is off the fire limit protection, and the second stage protection is off control limit protection. When the hook up to the safety limit position, the first stage off the fire limit protection starts. When the first stage limit protection failure, the second stage limit immediately de-energize the total contacts to play a role on protection.
Dual brake protection
Metallurgical Electric Hoist operating in dangerous environment, with double brakes. During normal operation, the second brake does not work, and only when lifting heavy object, the first brake failure or shaft and gear broken, the object falls freely, drum speed reaches a certain speed (1.25 times than normal speed), then the second brake braking the object in the air in order to achieve safe braking.
High temperature protection
Metallurgical Electric Hoist set the insulation protection in the below, effectively avoid direct heat radiation. In order to prevent the wire rope or cable from damage under high temperature during operation, there use high temperature resistance steel core wire rope and cable.
Operation Mode
In order to ensure the safety of operating personnel and equipment, Metallurgical Electric Hoist set up with remote control and ground control operation together use control mode. Mainly use remote control. Ground control operation only used temporarily when remote control operation fails.
Safety devices
In addition to double limit protection, dual brake protection and high temperature protection, as well as short-circuit protection, no-voltage protection, electrical interlock protection, overspeed protection and other multiple security protection devices.
