| DESCRIPTION |
| |
DIRECT DRIVE
A direct-drive design increases the efficiency of the capstan
winch and eliminates drive chains or bull gears to maximize
power output. |
| |
ANY ANGLE
The rope can leave the drum at any angle, enabling the operator
to stand in the most appropriate, out of line of sight location.
For safety the load line shall be the bottom wrap on the drum,
and the lead line going to the operator will be the top wrap on
the drum |
| |
GEAR REDUCERS
All capstan winches utilize high-efficiency worm,
helical, helical-worm or helical-bevel reducers plus
high-capacity, anti-friction bearings designed for long life,
low noise and higher output torque. |
| |
HIGH STARTING LOADS
High-starting-torque, 3-phase motors are available in all
standard voltages at 50 and 60 Hz. These motors are suited to
railcar pulling where momentary overloads occur when a railcar
is started in motion. Single phase motors at 115/230 volts at 50
or 60 Hz are available as an option on some models. |

| OPTIONS |
| |
CONTROLS
Capstans can be supplied with start/stop, foot-operated controls
of the “deadman” variety. If the operator’s foot moves off the
switch, the capstan will stop. This type of control allows the
operator to use two hands on the rope, for optimum control. |
| |
HYDRAULIC AND AIR-DRIVEN MOTORS
Capstan winches can be supplied with electric, hydraulic or air
motors. |
| |
EXPLOSION PROOF
Fully explosion-proof motors and controls are available for
applications in hostile or volatile environments. |
| |
TORQUE LIMITATION
Capstans can be supplied with a variable frequency drive (VFD)
package. The VFD controls the amount of current that the motor
can draw, limiting the amount of torque that the electric motor
can produce. |
