single drives or dual drives.

Dual drives have two

motors, two brakes, and

two drive modules, for high-

brake operation horsepower capability.

When winching in, the Multi-disc Brake remains applied with the hydraulic motor driving directly
into the gear reduction, through an overrunning clutch. When winching stops, the overrunning
clutch locks the input shaft to the already applied Multi-disc Brake ensuring no slippage of the
load. When powering out, the hydraulic motor is pressurized for the opposite rotation. This
pressure is also applied to the Multi-disc Brake, releasing it fully. The Brake Valve then controls
the speed of the load in response to the operator demand. When the operator intends to stop,
the main control valve is moved to neutral, the pressure diminishes, the Brake Valve closes to
stop the load, and the Multi-disc Brake applies as a “parking” brake to positively hold the load.

LANTEC LW Series Winches This chart shows the estimated gross cable capacity (feet) of the drum, assuming proper spooling.

Capacities shown assume a full drum, with the top layer of cable not exceeding the flange diameter.
No allowance has been made for “free flange” or “free board” which may be dictated by codes or
Cable Drum Capacities rules relevant to the application. No allowance has been made for “dead” wraps (mandatory minimum
of 3 “dead” wraps of cable to be left on the drum at all times).

LANTEC is pleased to provide a layer-by-layer drum capacity chart upon request.

LANTEC LW Series Winches

LANTEC LW Series Winches are available with a wide variety of optional

Options & Accessories
configurations and accessories to create the winch that meets all your needs.

Drum Configurations Beyond the range of standard drums, LANTEC offers:

• Alternate drum sizes quickly and efficiently manufactured to match your cable storage requirements
• Special cable anchoring methods including synthetic rope anchoring
• Multiple cable anchors for multiple cable or “On-Off” applications
• Drum divider for multiple cable applications
• Grooved drums with spiral grooving

options & accessories

• LeBus® parallel groove drum sleeves

Optional Gear Ratios LANTEC offers optional gear ratios to permit the most economical matching of
performance requirements with the available hydraulic power and motor selection.

Hydraulic Motor LANTEC supplies the winch with a hydraulic motor that matches the customer’s
hydraulic system to provide optimum performance. Winches are also available without motors for
customers who prefer to supply their own.

Motor Mounting Configurations LANTEC provides either an SAE C or D motor mount. Other
motor mounting configurations are available to support most hydraulic motors including DIN and ISO
standards.

Ratchet & Pawl LANTEC offers a spring engaged, hydraulic pressure released ratchet and pawl
package. Manual operation is also available.

Multi-disc Brake LANTEC includes a standard multi-disc, friction brake with a sprag type, overrunning
clutch for optimum performance in most applications. The brake is available without the overrunning
clutch for applications requiring a brake effective in both directions, such as slewing, vanging or
positioning.

Drum Brake LANTEC offers a band brake acting directly on the drum. Band brakes are available with
a variety of actuator types and in “marine duty” configurations.

Levelwind LANTEC provides a powered levelwind device to assist in proper cable spooling for
applications with a large fleet angle.

Drum Pressure Roller LANTEC provides a roller, forced into contact with the cable on the drum by
adjustable springs to help prevent “birdsnesting” and assist with cable spooling. This option is also
available with sensors indicating top and bottom layer conditions.

Encoder Drive LANTEC offers a light duty output shaft for driving a rotary encoder to monitor winch
drum speed and/or position.

LANTEC LW Series Winches utilize a

heavy-duty gear type motor designed with
Piston – Fixed Displacement

performance characteristics specifically

suited to winch applications. This is a
time proven and very durable hydraulic
motor well suited to most applications.

For high-pressure hydraulic systems employing

piston pumps and high-grade system
components, we offer LW Series Winches with
SAE C or D motor mounting configurations.

LANTEC can supply the winch with a variety

of motor types and sizes to best match your
system configuration and performance needs.
Piston – Variable Displacement

Some equipment manufacturers prefer

to retain complete system responsibility.
Therefore, we also offer the LW Series Winch
shipped from the factory without a motor. This

Minimum Determine the minimum allowable drum barrel diameter. This is often dictated by
Drum Barrel codes or rules relevant to the application and often expressed as a “Minimum D:d
Diameter Ratio”, that is, the ratio of first layer pitch diameter to cable diameter. This ratio affects in
cable bending stress and wear; generally the larger the D:d ratio the longer the cable mm
life will be. LANTEC recommends a minimum of 14:1 for most applications.
