A sealing gasket 30 is bonded to the inner wall of the mounting groove 5. The oil absorbing pad 29 is square in shape and made of soft material. The oil absorbing pad 29 is stuck between the connection between the lower assembly shell 3 and the upper assembly shell 4. The sealing gasket 30 is symmetrically bonded to the inner wall of the mounting groove 5 in the front and rear. The sealing gasket 30 is provided with a hole that is compatible with the compression rod 8 and the fixing screw 13. The setting of the oil absorbing pad 29 can absorb the engine oil of the internal mechanism to avoid increasing the difficulty of subsequent sanitary maintenance operations. The setting of the sealing gasket 30 can make the installation of the mounting seat 2 on the mounting base 1 more secure.
[0026] When using the new European hoist-specific lifting reducer, first fix the mounting base 2 inside the mounting groove 5 on the mounting base 1, then preliminarily fix the upper assembly housing 4 to the top of the lower assembly housing 3 through the positioning groove 18, then insert the connecting bolt 15 into the inside of the mounting hole 17 and screw the connecting nut 16 on the bottom end of the connecting bolt 15, so as to connect and fix the upper assembly housing 4 and the lower assembly housing 3, and then start the drive motor 21 to drive the drive shaft 22 and the first gear 23 to rotate, so as to drive the meshing second gear 23 to rotate.
