1t portable mini electric chain hoist for construction

portable mini electric chain hoist Specifications & Advantages: 1.original guide chain The guide chain originally devised makes it possible that the load chain can freely lift and fall. 2.advanced suction totary motor brake Suction rotary motor brake made of non-asbestos can precisely and effectively make the hoist stop running, even when there is a lack of power. Generally speaking, only when alternating current/direct current brake is installed can the brake work with power off and the hoist work with power on, thus the load will not fall due to the closed circuit of motor 3.High frequency motor with cooling fan The high frequency motor with cooling fan increases short time rating and repeated rating. Besides, class F insulated motor makes high frequency use possible. 4.low noised transmission gear The precise spiral gears made of intensive alloy steel are soaked in the oil so that the hoist wii serve longer life noiselessly. 5.Upper/lower limit switch This kind of switch is preventive against over lifting or over falling. Once it occurs, the switch can put a stop to the working hoist. 6.High durable chain bag Canvas chain bag is of notable duration. 7.Intensive aluminum case The original moulded hoist case with light structure and notable appearance quite appeals your attention. 8.Special over-rolling protection device The newly designed device with the characteristic of friction clutch soaked in the oil prevents the hoist extremely rolling up or being overloaded. 9.convenient examination and maintenance The control case cover fixxed with hinge is convenient for spot examination and maintenance. All the electric switch groups are installed on the same board. 10.Durable Buttons Buttons are convenient to operate, they are designed for low voltage control to ensure safety.
