Description

Technical Field

[0001] The utility model relates to the field of cranes, in particular to a cab of a rotary column portal crane. Background Art

[0002] The working principle of the slewing gantry crane is mainly based on the lever principle of the boom and the pulley principle of the winch;

[0003] The slewing gantry crane has a vertical tower with a rotatable boom installed on the top. The boom is equipped with wire ropes and pulleys for lifting heavy objects. When lifting heavy objects, the boom is driven by a winch to wind the wire rope around the drum, causing the heavy objects to rise or fall.

[0004] Specifically, when heavy objects need to be lifted, the winch will lift the heavy objects through the wire rope, and the boom will rotate to the specified position as needed; during the lifting process, the length and angle of the boom can be adjusted to meet different lifting needs;

[0005] A cab is installed on the crane, and the staff operates the crane inside the cab. The main body above the front window of the cab is not equipped with a rain shield component. When it rains, rainwater accumulated on the top of the cab will flow onto the front window. Although there are wipers to remove water from the windshield of the cab, the frequent swinging of the wipers back and forth will block the driver's line of sight, posing a safety hazard.
