15 ton chain hoist is often used within a workshop to lifting tools, this kind of small volume, light weight, convenient installation, operation and lifting hoist are very stable, has begun to replace bulky type 15 ton hoist. Before buying the electric chain hoist, according to the following several points to identify the quality of electrical chain block. First of all, after turning on the power supply, control electric chain hoist to move around, observe if the direction key is correct, also pay attention to whether or not there is brake voice when stopped. And, check whether the chain is down or not after stopping, if there is, that means the sheet is too loose, or is not installed properly. If these no problem, click on the button to up and down, observe the running distance, the smaller the 15 ton hoist run, the better. In some factory or workshop, sometimes need to run relatively small distance. Such as installing or docking, need 15 ton hoist rise or fall slowly, to facilitate calibration and installation, but electrical chain block is mostly single speed, even double speed is not slow enough to meet the requirement of installation speed. In this case, it need click stop to make the running time very short, so the moving range is relatively small, and can calibrate in each time point, until the equipment installation is complete. This is reason of why in the choice of 15 ton chain hoist need to click stop to check the lifting distance, in principle, the smaller the lifting distance is, the better.
