The NDS type of electric wire rope hoist
Starting weight of 3.2 ~ 80t
Weight configuration with Vice hooked 10/3.2 ~ 80/20t
Standard lifting height of up to 18m.
The running speed is 2 ~ 20m/min stepless frequency control
Standard Lifting speed 5/0.8m/min, the choice of frequency control, electric hoist, smooth braking, lifting objects swing amplitude, precise positioning, operating performance is greatly improved. The level of the basic work of the electric hoist design M5.
NDS type wire rope electric hoist reducer specialty products using imported German ABM Company crane, the transmission system to an enclosed structure designed to work when the transmission gear immersed in lubricant to improve gear life and reduce noise. Reducer gear using 20CrNiMo low-carbon alloy steel after carburizing, grinding process processing the teeth surface hardness above 60HRC Hardened reducer requirements, gear manufacturing precision more than six reducer 10 years Free maintenance design.
Electric Hoist Lifting motor with low vibration, low noise design of squirrel cage cylindrical 2/12 pole two-speed brake motors, lifting speed 6:1 relationship between the speed of two speeds, fast and slow in combination reached the true sense of the operation is convenient and fast, accurate positioning. Motor electrical connection continued rate of not less than 60%, F class insulation, motor protection not less than IP55, overheating protection and alarm functions, the motor housing is made of aluminum alloy drawing molding, excellent cooling effect. Also be based on user requirements using 4-pole inverter motor, achieve variable speed for precision installation with PLC programmable logic controller positioning of anti-sway.
NDS-type wire rope electric hoist maintenance free electromagnetic disc brake, in the event of a power failure in the braking state to ensure safety. Maintenance-free design that brake pads wear, brake clearance compensation, brake pad material environmental asbestos-free, modular built-in electronic brake system to brake fast agile. The minimum braking safety factor of 1.8, and the safety brake is not less than 100 million times.
