                        1) Crane drum structure



                        2) Crane drum description  


                           The crane drum is one of the most crucial components in the crane equipment , with unique functions to wind steel ropes of the hosting or towing mechanism whereby converting the rotary motion of the driving unit into the linear motion of the rope .


                        3) Crane rope drum advantages and features


                            a. Thanks to the simple structure , crane drum adjustment and installation become rather convenient .

                            b. During crane drum operation, steel wire rope seat themselves properly into the spiral grooves arranged around the circumference of the cable drum.

                            c. Ensure a proper level of stress evenly acting upon the steel wire rope .

                            d. Crane drum standardized design is suited to various lifting heights .

                            e . crane drum material : low-carbon alloy steel , such as Q345B , S355 J2G3 and so on or    according client request .

                            f. Welding test :100%UT and MT 

                            g. groove heat treatment by intermediate frequency quenching , hardness HB330-350 and deep around  ≥1.5mm .

                            h. High strength ,light weight and great rigidity  

                            i. Lager-diameter drum with small drum width enables a safe fleet angle, which in turn extends the use life of the cable
