Title:
LANDING DEVICE FOR SEMITRAILER
Document Type and Number:
Japanese Patent JP2627038
Kind Code:
B2
Abstract:
PURPOSE: To construct a two speed double reduction gear assembly with fewer parts so as to have a simple structure and be compact in size, and accommodate the assembly substantially in a landing gear leg.
CONSTITUTION: The semitrailer is provided, at the front end thereof, with first and second upright and telescopically extensible legs 11 with an interval therebetween in a transverse direction, and an input shaft 75 and an output shaft 42 which are transversely and rotatably disposed on the first leg, the output shaft being connected to an input shaft of the second leg. There is also provided a gear means located substantially adjacent to the individual input and output shafts to operate a landing device in either a high or low gear position, in which when a gear means of the input and output shafts of the first leg is switched to a low position, the ratio of the revolution of the input shaft to a vertically travel distance of both legs is from about 15 to about 50, and when switched to a high position, the ratio is from about 2 to about 5.
