ドラムs group consists of mandrel shaft, flange inner ring, mandrel hub, bearing and bearing seat. When one end of the mandrel shaft is equipped with a switch of a rotary rise limit position limiter, it must be ensured that the mandrel shaft rotates synchronously with the rotation of the rise limit switch.
1. When the fetching device is in the upper limit position, the wire rope is fully rolled in the spiral groove; In the lower limit position of the fetching device, there should be 1.5 rings of fixed wire rope groove and more than 2 rings of safety groove at each end of the fixing place.
2. ドラムグループの動作状態を定期的に確認し、問題があれば適時に対処します。
3. ドラムと巻き取りワイヤーロープ間の傾斜角度は、単層巻き取り機構の場合は3.5度以下、多層巻き取り機構の場合は2度以下とする。
4. Multi-layer winding drum, end should be edge. The edge shall be twice the diameter of the wire rope or the width of the chain than the outer wire rope or chain. Single winding single reel shall also meet the above requirements.
5. ドラムグループの部品が揃っており、ドラムは柔軟に回転します。詰まり現象や異常音が発生しないこと。
Actuate the reel and raise the wire rope until the new rope rises to the reel. Disassemble the connection of the old and new rope head, tie the new rope head temporarily on the trolley frame, and then start the drum, place the old rope on the ground. Wrap the new wire rope around the rope tray specially used for replacing the wire rope, cut it off according to the required length, and wrap the broken end with fine wire to prevent loose. Transport it to the crane and put it under the bracket that can make the rope disc rotate.
フックを地面に下ろし、ワイヤーロープを数回往復させて切断し、滑車を垂直に置き、リールを動かして古いワイヤーロープをこれ以上置けなくなるまで下ろします。
If another lift rope is used, the other end of the new rope should also be lifted up and the two ends of the rope fixed to the drum. When the lifting mechanism is started, the new wire rope is wound around the drum and the final replacement is completed.
