WIRE ROPE HOISTS
 |
RANGE :-
Capacity : 0.5 Tons to 45 Tons
Lift : 0.5 Mtr to 18 Mtr.DESIGN: Compact dimensions, low
weight, easy to operate and easy to maintain, modular design
with direct fits between components. Generally in accordance
with IS 3938.
MOTORS: S. CRANE uses sturdy
cylindrical rotor pole-changing motors with elegant continuous
cast aluminium sections, integrated safety brakes. Insulation
class - F, Protection- IP54. Specifically designed for high
starting torque hoisting service, half-hour rated with
permanently lubricated bearings suitable for frequent reversals
as well as braking.
|
GEAR BOXES: Precision flat
helical/ spur gear units with case-hardened gears, high-grade
surface treatment and permanent oil/grease lubrication. Newer
designs are lighter in weight because of improved material
strength & manufacturing techniques.
BRAKES: Single/ Dual-disc
electromagnetic DC brakes featuring automatic braking on power
failure.
Environmentally sound brake linings designed for approx. I
million braking operations allow long maintenance intervals.
,
ELECTRICAL PANEL : Modular design, covering a very wide
operating range. The panels are designed for ease of
installation, maintenance and reliable operation, with, fuseless
circuitry. Each drive group is equipped with a motor overload
protection device to provide effective protection against
inadmissible overloading. Control circuit provides reduced
voltage at the Push Button station, with 110 volts being
standard. Also, a relay to prevent phase failure and phase
sequence change at the incoming. Modular soft starts for cross
and long travel motors, ensures, operation is much more gentle
on components, lowering shock loads and heat buildup.
PAINTING: Every component & part
is thoroughly scrubbed & painted with two coats of primer before
assembly & two coats of synthetic enamel/automotive paint after
testing.
SUPPORTING STRUCTURE, TROLLEYS
AND DRIVE SYSTEMS: The trolley types are the result of
integrating standard hoists in chassis designed for different
applications and combining them with various types of travelling
gear.
In addition articulated joints ensure that all four wheels are
always firmly positioned on the tracks and that the wheel loads
are properly distributed in accordance with the structural
design of the system.
SPECIAL FEATURES :-
- LIMIT SWITCHES (PROXIMITY)
: To prevent over Hoisting & over lowering of hook. Positive
action limit switch will prevent over travel beyond set
limits in either direction. (Optional if desired for CT and
LT.)
- PUSH BUTTON STATIONS:
Extra light, handy, easy to operate, aluminium, fabricated
from extruded section. Weather proof as standard, giving
sure grip, one handed control, Station has built in steel
strain relief, permits pulling of unloaded hoist along
track. ROCKER switches in certain designs.
OPTIONAL :-
- Two speeds in all drives.
- Limit switches & brakes in
cross travel drive.
- Independent push button
station for bulky jobs.
(. Flame proof Hoists suitable for Gas Group I, IIA &IIB.
We at S.CRANE would be glad to
assist you in designing & installing overhead structures &
supports to ensure safe, smooth & economical materials handling
for your application.
All components generally designed in compliance with is-so 7 &
is-3177
