Pulleys and pulley sheaves and pulleys are often used in the lifting. 1, pulley sheaves and model from the weight pulleys: Q = 0.1nD2 Q --- safe lifting weight pulley (kg); D --- pulley diameter (mm); d --- pulley number. Pulley applications (illustration) (1) fixed pulley (2) movable pulley (3) guide pulley 2, five pulley block (1) effort pulley (2) rope point to wear around and fixed equipment relocation: 1, first of all to focus fixed heavy lifting equipment, easy place to bump damping measures must be taken to prevent the bump. 2, if the device is a precision instrument handling, we must first understand the most vulnerable part of the instrument which lifting equipment installation company, certain do special care, the general air bubble film, blankets and other specialized equipment lifting damping measures, the use of lifting equipment have to be careful when handling treated. 3, for the balance of poor equipment, the best is to add load base balance in order to secure the device to prevent tilting bump. 4, if the device is experiencing relatively high, I have a professional company dedicated chain hoists and tight rope device and allow the car to be fixed on both sides for easy transport. 5, the last is to looking for an experienced driver, constant speed to be able to ensure the safety of home equipment specialist lifting equipment |.
