[0004] High-rise residential buildings are currently the mainstream of urban housing buildings, and have the advantages of high land utilization rate and occupancy rate. However, there are some inconveniences when the high-rise residential buildings are in use, namely, it is difficult to carry large-sized or heavy furniture or materials, etc., especially for residents living above the 7th floor. For example, a certain Yangliu Shanzhuang residential area has 28 18-storey residential buildings and four 33-storey residential buildings. For each building, there are four apartments on each floor, two elevators, one staircase and two light wells. The dimensions of the elevator car are 1.6 m x 1.4 m x 2.3 m (L x W x H), with a maximum loading capacity of 10 persons or 800 Kg. The inner dimensions of the light well are 2.0 m x 3.5 m (W x L). An owner living on a high floor in this residential area purchased a sofa which is 2.5 m long, 1.1 m wide and 1.2 m high. Because the sofa size exceeds the dimensions of the elevator car, he had to manually carry the sofa via the stairs. He hardly managed to move it to his apartment on 15/F with the help of six people. The job took several hours, and costed RMB 2,500.
[0005] In the light of the above conditions, object carrying via the stairs has the following shortages:
[0006] 1. Manual carrying via the stairs is tiring and disturbing; there are safety issues concerning the handling personnel, the objects, and even the stairs; safety or quality accidents causing injuries and damages may occur.
[0007] 2. Long carrying time and high expense makes it economically undesirable.
[0008] 3. If the dimensions of an object exceed the maximum allowable size of the stairs or it weighs more than 200 Kg, it cannot be carried via the stairs.
[0009] Hence, it is necessary to select reliable methods with a high degree of mechanization for carrying, so as to ensure safety and quality, support larger and heavier objects, and save labor and cost.
[0010] Through prior art searches, no technical solutions similar to the patent have been searched.
[0011] The present invention aims to overcome the shortages of the prior art and provide a safe, convenient and labor/time saving method for carrying objects by a girder crane lifting device arranged in a light well.
