Can the crane’s legs be raised and lowered? If it cannot be raised or lowered, then how can the levelness of the four legs be adjusted during crane operations? Can the legs be extended to any desired length, or must they be fully extended? Are there cranes with 6 legs? Can a crane be positioned anywhere, as long as there is a sufficiently solid surface beneath it and its 6 legs are on the same level?
Can the crane’s legs be raised and lowered? Then entry to the factory is not allowed, and its use is prohibited!
The crane’s legs can be raised and lowered; all legs must be extended, and the crane must be on a flat, solid surface.
The crane legs can be raised and lowered, and they must be on a solid ground surface; if there is soil, mud, etc., sleepers should be used for support.
The legs of a crane are used to support it, ensuring that the crane remains at the same level and that the load is distributed evenly across these legs; this helps to keep the center of gravity stable during lifting. Otherwise, the cranes would have been crushed and overturned.
