Excavator operators usually work out in the field or construction sites; therefore, cautious investigation on the worksites is crucial to the safety of the excavator operator and to the safe operation. First of all, the operator should check the terrain and ground condition and use the safest operating method, try to avoid traveling or operating the excavator in areas with risk of landslide or falling stones, near cliffs, road shoulders or trenches, because the soft and loosen ground in these areas may not bear the excavator’s weight and vibration, as a result, the machine might sink or tumble down. The ground may become softer after heavy rain, explosion or earthquake. If the excavator has to work on a dam or near a ditch, vibration and machine weight may trigger a landslide, thus protective measures have to be taken prior to operation in order to prevent the excavator from tumbling down or falling over. For instance, to solidify the ground, keep a safe distance away from the ditch and assign a signal man when necessary.
If there are underground water mains, gas lines, cables or high voltage electric wires on the worksite, the large excavator operator must inform and ask related utilities providers to mark the area, and be careful not to cut any lines while digging the ground. When necessary, in order to prevent any unauthorized personnel from entering the construction site, it’s necessary to assign a signal man for the excavator operator and build a fence when operating on a highway. In addition, the operator must be extremely alert when operating on frozen ground as the excavator operation will cause the ambient temperature increase, which may result in soft and slippery ground. When traveling or operating the excavator in shallow water or soft ground, the operator has to check the type and condition of rock bed as well as the depth and water flow in advance.
