DESIGN, FEATURES &
SPECIFICATIONS :-
| S. CRANE GANTRY CRANES are
used for overhead materials handling where
existing columns do not have overhead brackets to support gantry &
rails. Or in open areas where columns cannot be accommodated. The top
main girder is mounted on two A shape columns which are further resting on wheel
mounted end carriages. Main Girder :- The girder is
designed considering the class, the frequency of
operation & the duty cycle. The girder could be RSJ type,
plate box type or truss type for single girder with its bottom flange as path for
trolley of hoist.
|
 |
| The girder
could also have a double girder design for heavy duty
applications, Where a suitable track is provided on top
of the girders for travel of crab wheels. |
STANDARD FEATURES :-
DESIGN :- Compact
dimensions, low weight, easy to operate and easy to
maintain, modular design with direct fits between components.
MOTORS :- S. CRANE uses sturdy
cylindrical / conical rotor pole-changing motors with elegant continuous cast aluminium sections, integrated
safety brakes insulation class F, IP54 protection.
GEAR BOXES :- Precision
flat helical / spur gear units in light alloy housings with case-hardened gears, high-grade surface treatment and
permanent oil / grease lubrication.
BRAKES :- Single /
Dual-disc electromagnetic DC brakes featuring automatic
braking on power failure. Environmentally sound brake linings
designed for
approx. 1 million braking operations allow long maintenance
intervals.
ELECTRICAL PANEL :- Modular design,
covering a very wide operating range. The systems are designed for ease of installation and maintenance
and reliable operation, with fuse less circuitry, ducted wiring and
non-screwed terminals. Each drive group is equipped with a motor
overload protection device to provide effective protection against inadmissible overloading.
PAINTING :- Every component
& part is thoroughly scrubbed & painted with
two coats of primer before assembly & two coats of synthetic enamel
after
testing.
SPECIAL FEATURES :-
- LIMIT SWITCHES :-
To
prevent over hoisting & over lowering of hook.
- PUSH BUTTON STATIONS
:- Extra light, handy, easy to operate, aluminium,
fabricated from extruded section.
- SOFT STARTS :- Electric /
Electronic soft start modules electrically coupled
to the long travel drives to achieve jerk free, cushioned &
smooth starts.
- MAINTENANCE PLATFORM WITH HAND
RAILING :- Easy, simple & safe
maintenance of the Crane extended partially or totally along the
girder.
OPTIONAL :-
- Two speeds in all drives.
- Limit switches & brakes in
cross travel drive.
- Independent push button
station for bulky jobs.
All components generally designed in compliance with is-so 7 &
is-3177
