Technical information on hydraulic motor
Characteristics of the Parker hydraulic motors installed to operate the 1140 winch (table 9):
Table 9
For both hydraulic motors: Input/return tube thread: 7/8 – 14 SAE
Drainage tube thread: 7/16 – 20 straight thread
Note (1): any flow range within the limits indicated is acceptable
Hydraulically operated winches have a load capacity proportional to the working pressure of the system, while the line
recovery speed is proportional to the oil flow.
Table 10
Note (2):
with very high flow values, for example 60 Lt/min, the gearing will need a more frequent maintenance cycle.
