Cranes must maintain a safe distance from trenches and excavations. A general Aramco rule of thumb is to stay at least 1.5 times the depth of the trench away from the edge. 6. Communication and Hand Signals

Tag lines must be made of non-conductive material (typically manila or polypropylene rope). rigger level 3 aramco notes

Screw pin shackles are acceptable for temporary rigging. Bolt-type (safety) shackles with a cotter pin must be used for semi-permanent applications or when the pin might rotate during the lift.

You are rigging a heat exchanger weighing 22,000 kg. You have two 8-foot wire rope slings (WLL: 15,000 kg each at vertical). The lift points are 3 meters apart. The hook height is 2.5 meters above the lift points. Is this safe?
