Gear
Reducers
All Jeamar 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.

pulling brochure, or see technical notes.
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 either 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.
