hydraulic winch
HYDRAULIC SYSTEM
The hydraulic system can be applied to all ANTAL winches from model W44 to W70 and also maxi W90.3.
The pressure of the system varies from 100 to 120 bars for the larger winches. Connections are to be carried out with 3/8” pipes.
All our hydraulic winches come supplied with a chromed bronze drum.
For manual use the gearbox is released simply by inserting the handle.

LINE SPEED
Line speeds are calculated in absence of load conditions and considering the flow of the lower table. The effective speed will be evaluated according to the actual size of the hydraulic unit.

HYDRAULIC UNIT
These units are dimensioned to the different requirements of each boat.
The winch speed is proportional to the flow from the hydraulic unit, the load of the winch is proportional to the pressure.
The hydraulic unit that must work a number of winches at the same time, must guarantee a flow equal to the sum of the flows required from each one.
The flow and pressure levels given in the table for each winch must not be exceeded.
All these models are fitted with Danfoss hydraulic motors series OMR or equivalent.
 

Mod. 251.305

 SWITCHES
Two switches with watertight protection and stainless steel cover must be installed for each winch. To identify the first and the second speed 2 colors are used: gray and red.
