Lifting molten metal electric Wire Rope Hoist

Lifting molten metal electric Wire Rope Hoist

The inspection project of Wire Rope Hoist molten metal wire rope electric Wire Rope Hoist is generally referred to the "major maintenance supervision and inspection rules for installation and renovation of hoisting machinery"1'SGQ7016 January 2008 and "Rules for periodic inspection of hoisting machinery" rI’sGQ7015-2008.

The following inspection items were set up: equipment selection and technical data, main structural parts and rails, main mechanical parts, electrical and control systems, safety protection devices, safety performance tests, etc. According to the characteristics of the equipment, the inspection items can be added or subtracted. The steel wire rope electric Wire Rope Hoist, need to pay attention to the following content,

When the rated lifting weight is not more than 5 t, the Wire Rope Hoist mechanism should be used to set up high speed working brake and low speed safety brake. (or choose lifting mechanism according to 1.5 times rated lifting weight design, with only high-speed working brake electric hoist; Or choose the lifting mechanism to select the lifting weight of the electric hoist for high-speed working brakes only by 1.5 times the maximum lifting capacity) Working grade of hoisting mechanism not lower than M6 (modified electric hoist used in service is not lower than M5), Wire rope electric hoist with heat insulation dust protection function and sufficient safety factor.

When the rated weight is more than 5T, but not more than lOt, the lifting mechanism should be selected to set up the high speed working brake and the low speed level (drum) safety brake. The working grade of hoisting mechanism is not lower than M6 (the modified electric hoist used in service is no less than M5N), has the function of heat insulation and dustproof protection and the requirement of sufficient safety factor, etc.
