Description

Technical Field

[0001] The invention relates to the field of equipment, in particular to a movable and lightweight balcony crane. Background Art

[0002] Balcony cranes are a convenient tool for transferring items between indoor and outdoor areas in buildings without elevators. Common balcony cranes on the market can be roughly divided into the following three types:

[0003] 1. Fixed wall rotary type: Fixed wall rotary type is a way to transfer objects by installing a steel pipe on the side wall with expansion screws to extend the rotatable boom. This type of hoist has the following disadvantages: 1. The force on the wall is very limited, and only light objects can be hung; 2. Damage to the wall leaves traces; 3. The volume of objects hoisted indoors by the rotary type is greatly limited; 4. There is no insurance measure when the assessed weight is overloaded.

[0004] 2. Ceiling support rotary type: Ceiling support rotary type is a way to transfer objects by connecting the ground and the ceiling with a retractable steel pipe to extend a rotatable crane arm. This type of hoist has the following disadvantages: 1. It is easy to cause cracks on the bottom and ceiling when lifting heavy objects; 2. It is easy to leave ugly marks on the house; 3. The volume of objects hoisted indoors by the rotary type is greatly limited; 4. There is no insurance measure when the assessed weight is overloaded.

[0005] 3. Rotary base: Rotary base is a way to transfer objects by connecting a support tube with a counterweight on the base to extend a rotatable boom. This type of hoist has the following disadvantages: 1. It is too heavy and not easy to carry; 2. The volume of objects hoisted indoors by the rotary type is greatly limited; 3. There is no insurance measure when the assessed weight is overloaded.
