Why use IW-ASRS at Parel Depot
Parel workshop has one of the smallest footprint to
Coach POH ratio.
Located in the heart of Metropolitan city-Mumbai
with costly land where lateral expansion is not an
POH target of ICF, LHB increasing.
Area can be released for workshop modernization &
expansion activities only by releasing the dead space
being occupied by multifarious stores godowns.
This is where IW-ASRS comes into play.
IW-ASRS utilizes vertical storage capacity leading to
efficient storage & retrieval

for 100% duty cycle. Welded steel frame. Single mast tube,
strut braced. Structural steel base.
Drive and Idler Wheels: Flanged forged alloy steel. Case
Hardened to 55 Rockwell C. Reground for concentricity.
Heavy-duty pillow block bearing support.
Fork Extractor Mechanism:
• Construction: Precession fabricated steel
• Load Capacity: 1500 Kg.
• Load Support: Industrial Standard Forks
• Extractor Drive: Patented ball screw and rotator with
variable frequency drives, industrial gear reducers, and
Crane Rail with V-H Drives
• Floor mounted , Rail mounted .
Vertical & Horizontal Drives:
High performance sine-coded, pulse width modulated AC
vector motor drives which generates an adjustable
voltage/ frequency three phase output for complete speed
Automatic stall prevention and voltage boost prevents
nuisance tripping during load or line side transient
The drives will not induce any voltage or distortion back
into the utility line and maintains a displacement power
factor of not less than 0.98 throughout its speed range.
Communication & Controls
• Infrared Modem
S/R Machine Controls:
Electrical Components: IEEE code compliance
throughout. IEEE rated enclosure, sensors, and
wiring. Panel-mounted diagnostic indicator
lights. Panel-mounted maintenance controls.
Logistics and Positioning: Onboard
programmable controller A-B SLC-500®
communication by infrared modem. Steel code
bar, optical address readers. Fine positioning,
motor-mounted resolvers with 1/16'' accuracy or
1 deg. Accurate positioning on start-up.
Rack & Pallets
Front and rear aisle-obstruction detectors. Onboard
and off-board emergency stops. Load and centering
sensors and interlocks.
Virtually any post and beam (conventional) existing or
new racks capable of safely bearing the pallet loads
(pushback and flow rack). Continuity of vertical shelf
distance from floor not required. Common depth
dimension recommended, but differing depths can
often be accommodated. Racks must be attached to
the floor but no shimming is needed except with
extreme floor conditions.
Maximum Height: 100 ft.
Any two or four way pallet capable of being used.
