B1140 Winch 3
Introduction
B 1140 winches are used as primary winches on mega yachts. They are produced in a self-tailing version and, together with
the B 1150, are the only non Top-Drive winches we make (that is, they cannot be operated by a winch handle). This
limitation is due to the fact that they are designed for use on very big boats, where human strength alone would not be
enough to operate them.
The B 1140 winch has three speeds plus reverse (backwind). The backwind system makes a right-hand winch turn anti-
clockwise, thus lessening the tension before the sheet is eased. This means the line can be handled at loads within the
safety margin, and also prevents excessive wear on the sheet itself.
The B 1140 winch uses two hydraulic motors: a main one and one for backwind. On request it can also be powered by
electric motors of both 24 and 380 V, through specially made control boxes. But here it is important to take into account
the need for greater space below decks compared with that required by the equivalent hydraulic units.
In addition to hydraulic or electric power, the B 1140 can also be driven by coffee grinders or by a hybrid combination.
The 1140 self-tailing hydraulic winch is available in various configurations as shown in table 1 below:
