The invention discloses a lifting system which comprises a pedestal, a positioning element and a combined unit. The pedestal comprises a first base plane and a second base plane, wherein the second base plane comprises at least one first section and at least one second section. The positioning element can move between a first reference position and a first established position. The combined unit is connected with the positioning element and comprises a first device and a second device. The first device comprises a first body and the second device comprises a first element which has a first connection portion and a first contact portion, wherein the first connection portion of the first element is articulated with the first body, the first contact portion of the first element extends away from the first contact portion, and the first contact portion of the first element is detachably contacted with the first base plane.
Description
technical field [0001] The invention relates to a lifting system and its combination unit, in particular to a lifting system and its combination unit which can locate, install or remove objects to be hung. Background technique [0002] Generally speaking, high mast luminaires occupy a smaller area, require a wide range of lighting settings, and have a high average height. In order to facilitate the maintenance work of the staff, it is better that the relevant lifting device can lower the lamp holder for the lamp to the height of the staff. [0003] However, under the operation of strong wind or inexperienced staff, the lamp holder cannot be smoothly raised to the predetermined locking point, and when the lamp holder is about to reach the locking point, it is easy to be skewed, shifted, etc. Due to the situation, the tenon cannot be inserted into the locking point correctly, which may cause the lamp holder to be skewed, improperly hung or even dropped.
