i want to know about the container handling cranes.weight,height,color,heat and moisture resistance,...?

Question

I need to know exactly how much weight they can lift also how much do they weight?how long is thier life-time?in what temprature they can work?does mosture do any harm to them?for installation , do they need foundation?the exact height and width?

Answer 1

You need to be more specific. The lifting capacities for container cranes varies significantly, as does any other crane. Some of the variation is based purely on load (horsepower) availability; some is based on speed (rpm) for lift/drop portions of the cycle.

Cranes like these operate year-round, at ports all over the world. Some ports have average ambient temperatures in the range of 45 C, with highs up to 60 C. Others can be as low an average as 10 C, with a low peak as much as -50 C.

Moisture will, over the long haul, harm them - they're metal constructs, and thus are prone to oxidation. Using corrosion-resistant materials and/or coatings will certainly prolong their usable lifespan. The crane drives (electric motors and power electronics) are also susceptible to moisture and other contaminants.

All true "dockside" cranes require some sort of permanent foundation; it's usually part of the pier construction itself. However, there are "portable" cranes that operate without one.

There is also more than one crane manufacturer out there - all will have their "trade secrets" that will make each look a little different than the rest. It will generally also reflect in their operation parameters, and in their expected life cycle.
