The air winch Operator shall ensure that the winch wire is moving freely in the derrick ( possibly guided by pulleys) to avoid any damage to the steel structure, especially the fingerboard.

When hoisting any large or heavy equipment off the catwalk always check the Working Load Limit ( WLL) of the air winch, or use the travelling block or crane if available.

当从猫道上提升体积大或较重的设备时，要检查气动绞车的额定工作负荷，或使用游车或吊车（如果有）。

Clearly mark safe working load ( SWL) on the air winch below the rig floor.

标明钻台底下气动绞车的安全工作负荷。

Operate the air winch.
