Do not use it except for lifting drum. It is about slightly less than 1 ton if drum is filled with iron powder (lathe dust), etc. In this case, single hanging is dangerous. Change double hanging or reduce the amount. Not available to hang drum without edge. Use it after checking the chucking condition for grips of drum with changing edge and repaired reusing can. For safety, do not hang over 5pcs of drums at the same time.
