12 Integration and Assembly Technology of Lunar Lander

lander in lifting
the lunar lander and a lot of tools involved, it was necessary to propose a set of special
technological method for attitude adjustment and assembly, including test supports
with different angles, attitude adjustment of lifted the lunar lander, and assembly of
the lunar lander and test supports in horizontal or vertical status, so as to implement
attitude adjustment of antennas to be tested [17].
Two sets of single beam spreader were applied for lift and turnover of the Chang’E3 lunar lander in antenna test. Two sets of single beam spreader with tow lift points
were connected in sequence with two sets of cranes and lift points of the lunar lander.
The lifting distance of the corresponding spreaders was independently controlled by
two sets of cranes to implement 90° turnover of the lunar lander by control of the lift
distance (length of rope).
12.5.9 Transshipment and Transportation of Lunar Lander
1. Transshipment
The spacecraft and hardware need to be transported within the facility. Generally,
the assembly parking bracket, air-cushion vehicle, omnidirectional wheel transport,
AGV (Automated Guided Vehicle) intelligent transport technology and Mecanum
wheel are applied.
