1. New installation or maintenance after the demolition of the subject after installation of electric hoist, the first test run should be empty several times. But before installation, avoid power test switch. 2. The work should be carried out before 125% of the rated load, lifting off the ground about 100 mm, 10 minutes of static load test to check whether it is normal. 3. The dynamic load test was rated load weight, as repeatedly lift and move around the test, check the mechanical transmission parts after the test, the electrical part and the connecting portion is normally reliable. 4. In the case of the sha hoist, the absolute prohibition in impermissible environment, and exceed the rated load and rated switch per hour (120 times) situation. 5. installation and maintenance, must be strictly limiting device is flexible and reliable inspection, when the limit was raised to the position of the hook, hook it to the shell casing from the reel must be greater than 50mm (10t, 16t, 20t must be greater than 120mm). When the hook is lowered to the limit position, it should ensure that the reel ring rope safe, effective and safe rings must be at least 2 laps. 6. Press the two are not allowed in the opposite direction of the electric hoist motion control pendant button. 7. After the completion of work necessary to supply the total gate opened, cut off the power. 8. hoist by hand manipulation, the operator should fully understand the safety rules, non-hanging crooked oblique pull. 6, compact structure, electric hoist, good looks, has many unique innovations: (1) no leakage cable hoist body, through various means throughout the cables are arranged in a gourd inside, making gourd looks more beautiful; such as: the support shaft is hollow thick-walled pipe, to ensure the use of the strength of the premise, reducing the overall weight of the hoist and hoist through it about the passage of cables. Compact (2) gourd structure, the weight of the counterweight box, users can add a variety of steel scrap or stone, etc., saving the steel, while the more counterweight low-headroom hoist reduces the dimensions; (3) hoists run using NF series helical gear reducer drive hoist yale sides wheels transmit torque through a six-rowed steel, transmission torque, high reliability, to avoid the situation of the flat key shear failure, and this transmission is there conducive to the installation and adjustment of hoist operation portion; (4) Lifting the host portion of the cover is rectangular welded structure, surrounded by the mounting bolt holes are highly versatile, can be quickly transformed into fixed or suspended bogie traveling electric hoist, and 360 ° direction of the rope. 7, the entire structure for easy removal, installation, easy maintenance and good maintainability. sha _ generous hoist heavy (certified) _ Qujing hoist is provided by generous heavy machinery Co., Ltd., Henan Province.
