The main characteristics of the crane hoist ring mill Description 2) the use of electric cranes: two brake systems: (1) Motor brake (2) mechanical brake carrying four safety devices: (1) motor overload protection (2) electric limit switch (3) Emergency stop (4) overload slip clutch 2) rigid aluminum body structure, provide lightweight, compact and has a short suspension from the 3) with high tensile alloy steel bearing CHAIN, hot-dip galvanized and resistant to abrasion. 4) All of the gear and pinion axis is made of high quality alloy steel, has a very good surface hardness, and ends with an anti-friction ball bearings for support, the gear is running in a sealed oil bath. Usage: Suitable for engineering hanging plant hoist operations, civil hydropower pipe installation, storage access goods, where the lifting / Ascension / drag ... and other operations are suitable for wide range of uses. Small size, light weight, easy to obtain single-phase power supply, high effort and aging. ... Other models DU-906 hoist (kg) 2000 voltage 220V / 380V / 440V 3 Phase 3 long hang refining Number 2 Jan-speed (M / min) 50HZ-3 / 60HZ-3.5 horsepower (kw) 2 refining diameter ( mm) 7.1 Features: Motor systems: 1. Using industrial grade high efficiency squirrel cage induction motor 2. Multi-outlet type, there are three voltage selector configuration. 3. enameled heat levels up to 180 degrees, designed for a long time lifting specially designed. Brake System: 1. exclusive use of the motor unit and the gear unit Shuangsha vehicle systems. 2. Using high coefficient of friction disc type brakes to make, all without adjustment. 3. The power failure or malfunction immediately brake brake, safety marks, high life. Electronic control system: 1. Using DC-24V low voltage control, use no risk of electric shock when it rains, security and stability. 2. Use a large current cassette switchboard PCB circuit boards and Japanese relays, high quality, quick change, high life. Security systems: 1. chain operations reaching the upper limit and lower limit will automatically power off. 2. Built-in Phase-reverse protection device, three-phase power supply is automatically stopped if phase loss can not be used to protect the motor does not owe phase burned. 3. The three-phase power supply is automatically stopped if the reverse is still unable to use, safe and secure. Chain Size: 1. imported from Japan FEC chain manufacturing firms are manufacturing. Alloy steel triple safety factor of 2.80 rating. Gear system: 1. Use the best efficiency of the planetary reduction gear. 2. The planetary gear set of the two-stage, and the second output gear used four running steel heat treatment idler, sharing power, life is generally more than four times the transmission type. 3. The gearbox for the FCD-45C steel body shape, toughness strong, the computer CNC machining, high precision, low noise. Infrastructure: 1. With 5mm high strength steel supporting crane structure. 2. The strength of the molded three times. 3. The use of electricity than aluminum with paint, rust resistance, suitable for harsh environments -15 degrees to + 65 degrees. Housing parts: 1. The use of high strength steel by large tonnage of hydraulic bed one piece, no voids or engaged. 2. Fully sealed waterproof IP 65. 3. coefficient of automotive class powder coating, appearance, compact structure, effectively increasing job rose up and down stroke. Upper and lower hook Group: 1. Use steel hot forging molding, high strength, safety factor of 4 times. 2. By means of ball bearings in the hook can be rotated 360 degrees, no tangled chain risk when lifting heavy objects. Control switch: 1. Use the production of Taiwan's indirect push-button switch, small and easy to operate. 2. Water resistant up to IP65, high life. 3. Control line cable with a cable, the resistance to pull not broken.
