To be a responsible crane operator, the first thing you need to know is to find the right place on the construction site before operation. Here are some factors a crane operator must pay particular attention to.
Crane standing conditions or supporting conditions are of paramount importance to safe crane operation. Mobile cranes should only be used on even and firm ground in order to keep the machine stable and be capable of lifting the maximum load safely at the same time.
However, on most of the construction sites, perfect level surface is rare, thus in order to avoid potential collapse of the supporting surface and tipping over of the mobile crane, crane operator could use steel plate of high strength, suitable mats or timber blocking to make sure that the mobile crane can operate in safe conditions.
Besides, the crane operator should also take into account strong wind and other dynamic forces effect, frequently check and examine the supporting surface during the crane operation to ensure that there is no risk of movement affecting the machine's stability. This is especially necessary when the mobile crane is working on bridge decks, or nearby trenches and embankments. A safety distance should be maintained between the crane's standing area and the edge of soil slope.
In addition, crane operator must take proximity hazards seriously during crane operation or crane transportation. When mobile crane must travel under or work near to overhead electricity lines or cables, the operator and any person working in the vicinity should be able to take safety measures and strictly follow the safety instructions given by a signaler who has a clear view; otherwise, serious accident may occur.
Moreover, crane operator should try to site the crane as far as possible away from expressways, railways, air routes, and any underground services such as gas lines or electric cables.
If several cranes are working on the same construction site, crane operator should also attach great importance to the proximity of other cranes operating nearby. All the personnel on site including crane operators, signalers and slingers must coordinate with each other, trying to avoid collision of cranes while working in overlapping areas.
