OPERATION and MAINTENANCE
OF 12V DC Capstan Winch-Hoist
Parts List, Wiring and Mounting
INSTALLATION:
READ THIS BEFORE OPERATING UNIT
MAINTENANCE:
Mount on clean, flat surface. Bolt down with 4-1/2" bolts, grade 5 or
better, For ease of service, we do not recommend welding frame to
surface.
Connect a battery cable from the positive battery post or 12V DC power
supply to the positive post on the winch control box (p/n 281750) using the
boot provided. Connect a battery cable from the negative battery post to
the grounding post on the winch frame. The negative cable may not be
required when the winch and the battery or power supply are connected to
a common ground. Use #4 battery cable or larger for cable runs up to 10'.
Use #2 battery cable or
for cable runs from 11-25'. For vehicle
mounted applications, a
mounted disconnect switch may be used to
disconnect power to the winch when it is not in use. This will prevent
accidental engagement of the winch motor during travel. Contact My-te for
more information.
ROPE USAGE AND SAFETY:
The capstan drum winch-hoist is designed to be used with rope of 1/2" to
3/ 4" diameter to winch or hoist loads requiring up to 800 Lbs. of single
line pull. Polyester or Dacron rope makes a good rope choice due to its
resistance to heat generated by drum friction. Do not use wire rope.
Wrap the rope around the drum placing the load line closest to the gear
box. To hoist or retrieve the load, the operator must pull the fall line (the
unloaded end of the rope) from the drum by hand as the drum rotates. To
tower the load, carefully pay the fall line back onto the drum allowing the
wraps of rope to slip, thus lowering the load. An alternate method of
lowering a load is to operate the winch-hoist in the lifting direction while
paying rope back onto the drum.
The proper number of wraps is determined by feel. Take time to become
familiar with the capstan's operation. Feeding off and paying back of the
fall line should require minimal effort. Use at least 3 wraps of rope on the
drum. Heavier loads may require 4 wraps. Do not place so many wraps on
the drum as to allow the rope to ride over the end of the drum. If the load
requires excessive operator effort or more than 4 wraps of rope on the
drum, a two part line and traveling sheave block must be used. If this does
not alleviate the problem, check the weight e>f the load and be sure rope
travel and load path are unrestricted. Do not overload the winch-hoist!
OPERATION:
Extreme caution should be exercised when operating any winching or
hoisting equipment as loss of control over the load may result in property
damage, injury or death. Operation of such equipment should only be
performed by qualified personnel.
The 30-12 and 30-12/FS are designed for intermittent operation. My-te
recommends a 25% duty cycle. For optimum motor and control life, do not
exceed 15 minutes of run time per hour at full load.
To prevent shock loading, slowly remove slack from rope before full load is
moved.
Hand held or foot operated pendant provides forward and reverse control
through winch-hoist control solenoids. Pulling power is the same in either
direction.
If the unit is installed outside, a cover may be provided to protect motor
and controls from the inclement weather. Do not allow the cover to
interfere with the capstan drum.
Frequent inspection of the winch including battery cables and pendant
should be made to detect any damage that may affect proper operation of
the unit.
A periodic inspection should include a check of all hardware to ensure that
fasteners have not worked loose. This includes the locking collar on the
218010 flangette bearing assembly, as well as the capstan drum set
screws. Check the gear box oil and bearing lubrication as described in the
attached Lubrication Guide. Check electrical connections for corrosion.
TROUBLE SHOOTING AND REMEDIES:
If the unit does not run, check power supply. Be sure correct voltage is
being applied. Verify that the winch-hoist is well grounded to the 12.V DC
power supply.
Check all connections in the winch-hoist control box. Check connections in
the hand held or foot operated pendant.
Check for damage to the battery cables and pendant cord.
If a cab mounted cut-off switch or circuit breaker/fuse has been installed in
the power supply to the winch-hoist, check for proper wiring and operation
of these components.
If the control solenoid(s) click(s) but the winch-hoist does not run,
determine whether the problem is in the motor or the wi.nch-hoist control
panel. This may be done by checking for 12V DC voltage at the motor
terminals on the outboard end of the motor when the pendant switch is
operated. Operating the pendant in the opposite direction should reverse
polarity of the voltage. Proper voltage at the motor indicates that the
problem is most likely in the motor.
Motor brushes may be replaced. Contact the factory, your My-te dealer or
a motor repair shop for assistance. In order to remove the motor, the
118081 pinion gear must first be removed.
