Main Girder :-

• Economical design, using bigger cross-section of industrial bridge cranes with lesser amount of steel.
• Special lightweight construction of the double girder bridge cranes reduces load stress on building supports.
• Low Headroom ensuring maximum lift.
• Easy accessibility for maintainence.
• Bigger corss-section ensures lesser vibrations in girder.

Cross Travel Drive :-The use of a motor driven trolley with the hoist greatly increases the speed and efficiency of load handling. Steel frame side plates extend beyond wheels for end stop contact. Wheels are with contoured tread for use on standard tapered or wide flange flat beams. Traverse gear reducer is conservatively - rated rugged drive reducer with output pinion meshing with machine cut wheel gears.

Long Travel Drive :- Industrial double girder cranes comprises of an arrangement of solid shafts and floating shafts coupled by universal couplings and supported on pedestals blocks. The arrangement of double girder bridge cranes is driven by a crane duty foot mounted motor transmitting torque to heavy duty shaft mounted gear box, which transmits torque to output pinion, this pinion meshes with machine cut wheel gears. Rail sweeps are provided on end carriages and crab frame ends to clear of any object left on or learning against the rail ahead of the crane wheels. Rubbers Buffers are also provided an end-carriages & crab in the industrial double girder cranes. A Special Soft Start Unit is coupled to the LT Drive to ensure a smooth, cushioned & jerk free start of the girder bridge cranes.

RANGE
Capacity	0.5 Tons to 50 Tons
Span	0.5 Mtr. to 40 Mtr.
Lift	0.5 Mtr. to 30 Mtr.

S. CRANE UNDERSLUNG CRANES :-Special building characteristics often require a special crane design, S. CRANE underslung travelling cranes provide an optimal solution where the building structures make the normal travelling cranes less suitable. The main feature is that the crane track is not fastened to pillars but to the beams of the building. Over and above these special requirements the S. CRANE underslung travelling cranes offer the advantage of very small trolley approach dimensions and as a result an optimal utilization of the building width.

S. CRANE underslung travelling cranes provide a load capacity range of 0.5 T upto 10 T and spans of up 25m. An optimal area coverage can be achieved by individually fitting the cantilever. The highest hook position can be further increased by inserting the main girder between the end carriages.

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.

• 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.
