Line
shaft hoists are self-contained units
with a separate drum for each lift
line. |
| |
 |
|
•
|
No
wall or floor space is required for
the hoist, nor are head blocks or
loft blocks required. |
|
|
|
•
|
Due
to its design, the load placed on
the building structure is a vertical
load only, without the resultant and
compression loads associated with
conventional rigging. |
| |
|
|
•
|
Line
shaft winches are particularly useful
for renovations and in locations with
limited space. |
| |
 |
|
•
|
In
order to compensate for movements
in the structural steel as loads change,
J. R. Clancy line shaft hoists include
universal joints in the shafting between
the drums. This provides increased
reliability. |

Fixed
and variable speeds are available. |

| Key
Features |
|
|
•
|
The
motor, brake, and gearbox are an integrated
unit from a single manufacturer, for
quality assurance. A continuous shaft
links the brake, motor armature, and
the first stage pinion gear without
the need for couplings, for added
reliability and safety. |
| |
| |
|
|
•
|
The
brake is spring applied and electrically
released, for "fail safe"
operation. |
| |
|
|
•
|
Drums
are helically grooved to carry a single
layer of cable, for long cable life
and reliable operation. |
| |
|
|
•
|
Four
limit switches are provided for normal
end of travel and over travel protection.
The two circuits operate separately
for added safety. |
| |
 |
|
•
|
Hoists
can be furnished with continuous channel
bases or with individual bases for
each gearmotor and drum. |
