- the connection bracket 500 facilitates the assembly of the crossbar 400 and the lifting post 200, and reinforces the connection portion of the lifting post 200 and the crossbar 400, which receives the greatest force during lifting. do.
- the present invention maintains the lift state of the boat (1), and has a lifting holding portion for preventing the falling of the connecting bracket (500). Due to the lifting holding unit, the driving unit may be malfunctioned or the weight of the boat 1 may increase rapidly, and thus the rising state may be stably maintained.
- the covering part 133 of the present invention effectively limits the vertical movement of the connecting bracket 500 or the cross bar 400 to withstand external forces generated from the outside, and blocks the space exposed to the buoyancy unit 100 and is safe. It offers a beautiful appearance.
- the elevating fixing unit 134 installed in the covering unit 133 is installed so as to correspond to the external shape of the connecting bracket 500 or the cross bar 400 so that the connecting bracket 500 or the cross bar 400 is elevated. Due to being inserted into the government 134 to more firmly withstand external forces, vibrations, shocks generated in the up, down, left and right directions, the connecting bracket 500 or the cross bar 400 in the raised state is integral with the buoyancy unit 100 To increase the durability of the overall boat lift. At this time, the elastic pad installed on the elevating fixing part 134 may absorb some vibration or external force, thereby enabling more stable support.
- a guide side bearing 311 and a column side bearing 220 are installed in the space between the lifting guide 300 and the lifting post 200 of the present invention. Due to such a bearing portion, the lifting column 200 is capable of stable sliding movement and minimizes shaft torsion or twisting.
- the weights of the lifting columns 200 and the sliding speeds of the lifting columns 200 may be generated in the respective lifting columns 200. It can effectively withstand the torsion caused by the speed difference.
