Imported YSS-2000 Formosan black bear electric hoist lifting 20T

? YS-2000 Features Operating voltage 24V / 48V conversion, to prevent leakage when possible accidents, ensure the safe use when it rains. ? Dual brake system is safe and reliable. ? In the event of power failure, automatic braking system, automatic brake immediately. ? Hanging under the hanging limit switch to prevent exceeding the limit. ? Can install electronic overload and emergency switch. ? Special reverse power protection devices unravel, when the electric wire connection error margin, the control circuit can not be operated. 1. Shell? Alloy shell, solid and lightweight. ? There are special heat sink, heat quickly, can be used continuously, up to 40% efficiency. (Double speed 40/20%, YSF series 15%)? 2. Motor Brake? Newly designed magnetic generator, which is producing the magnetic characteristics. ? Can instantly cut off the power while the brakes, crane brakes ensure absolute safety when indeed. ? Patent No. 27417, registered documented. ? 3. Limit switch? Hanging under the hanging limit switch device, the automatic stop to prevent the chain beyond, to ensure safety. ? The chain? FEC80 imported super-strong heat treated alloy steel chain. ? 5. Hook? By hot forging, excellent strength, prone to breaking. ? Under the hook can be rotated 360 degrees, with safety tabs to ensure safe operation. ? 6. carriage? Hoists steel support frame by a combination of two very strong. ? 7. Mechanical brakes? Mechanical brakes special device to ensure safety when the super load. ? And motor brake combined into a "dual brake system" to strengthen its security and durability. ? 0.5 tons (YSL, YSF) no such device. ? 8. transformer? 24V / 48V transformer unit. ? When operating, if leakage, to prevent the occurrence of the accident, when it rains, but was even ensure safe use. ? 24V suitable for 1.5 / 1.8kw of horsepower, 48V applied to 3.7kw. ? 9. electromagnetic contactor? High efficiency electromagnetic contactor, in line with FEM 2m operating frequency. ? 10 reverse phase protection equipment? Unravel special electric device, when the power cord knot error, the control circuit can not be action. ? 11. button switch? Waterproof button switch, lightweight and durable.
