Industrial Cranes
Reva’s Double Girder EOT Cranes are fine examples of practical, intelligent, reliable , economical and
balanced solutions for Overhead Handling of loads. Be it for a foundry shop or a godown, our cranes
have been designed and manufactured for all needs. By embracing high level of standardisation and
continuous evolution of our components for the past 5 decades, we have come to serve an honourable
clientele, which includes, BHEL, SAIL, Tata, L&T and many more.
Read on to know why Reva’s cranes are your best bet!
Travelling Machinery
Compact modular travelling machinery unit consists of a hollow output shaft
gear box to be mounted directly on the wheel axle thus eliminating any
chance of misalignment. These units are maintenance free and supplied with
squirrel cage/slip ring motors with disc/electro-hydraulic thruster brakes.
The gears and pinion in the travelling machinery are 100% helical, hardened
acheiving 99% efficiency.
Crane Wheels
The double flanged cylindrical wheels are made from high
strength C55MH75 steel. Running surfaces are hardened to
26 HRC. The wheels run on self aligning antifriction roller
bearings and have substantial flanges on either side of the
machined running face. The wheels are shrunk fit onto their
respective axles. The split housing design allow easy
replacement of the wheels.
End Carriages
End Carriages are of standardised wheel bases in R-10 series.
These Box shaped carriages are of welded construction with R-Block
bearings. The fabricated end carriages are machined on a horizontal
boring machine ensuring perfect axial alignment, parallelism and
perpendicularity of the wheels individually and in pairs.The
construction of R blocks is such that it is easy wheel
maintenance/change. Rubber/spring buffers are supplied according to
requirements.
Planetary Gear Boxes /Micro-Drives
Depending on customer needs the crane can be equipped
with micro-drive using Reva’s own well balanced planetary
gear boxes for obtaining creep speeds (ratio 10:1 or 5:1) for
hoisting, traveling and traversing motions. The planetary
units have favourable volume to power ratio because of
power sharing between gear meshes.

4.
Cabin
Constructed from sheet-metal the cabins are suspended either
on one side of the crane or in the middle. They are open types
for indoor use or close types for outdoor use. Air conditioned
cabins are also available. All cabins have a protective panel and
controls are ergonomically placed for maximum comfort to the
operator. Emergency switches too are provided.
Controls
Pendant, cabin or radio remote
operated cranes can be supplied in any
mode or combination of modes. As a
standard Trailing type Pendant is
provided in Double Girder crane.
Adequate protection by way of single
phasing, phasing reversal, overloads ,
brakes are some of the standard
features. Dynamic brakes suitable for
slipring/squirrel cage motors for precise
handling can also be supplied. The sheet
steel-metal housings are constructed to
accommodate the power and control
circuits in a single cubicle having
built-in cable trench underneath. The
spacings and making are as per IS
specification. Cranes with VVVFD
control can help achieve stepless speed
variation and have various inbuilt
motor protections.
Brakes
Reva provides 100% Redundancy in Hoisting brakes by
providing 2 brakes each of 150% of the required torque.
The thruster brake are operated by an integral 3 phase
squirrel cage motor. In travelling motions, electromagnetic
disc brakes are mounted directly on motors. D.C brakes
and other combinations for hoisting and other motions can
be provided for specific application on request.
Rope System
The drums are made of seamless steel
pipes or pipes fabricated from plates
tested as per ATSM/IS. The drum is
coupled to the gearbox and this
facilitates easy removal and
maintenance. Wire rope is fixed with
double slot camps. Nonrotating, high
strength special Hyflex wire ropes,
manufactured for use on hoisting
equipment, are used with safety as per
IS standards.

5.

Structure
Tested steel plates to IS:2062 Gr. A or B are
obtained directly from the main steel producers and
cut to needed sizes, All weldings are done with Modern
day welding machines and qualified and experienced
welders ensuring proper edge preparations and weld fit-ups etc.
Further radiography is used for weld in tension to ensure perfect weld.
Certain percentage of tillet weld is subjected to DPT (dye penetrant
test). We have used techniques to avoid distortion and reduce stress
concentrations. Proper comber is provided for long life of the girders.
Design
The strength of any product is ensured by its design. At Reva, we lay
special emphasis on the all aspects of design - functional, structural,
aesthetic and economic. There is a continuous evolution of the
components and of the production processes at our design
department, to give you improved functionality
and new features in the product line.
We are fully equipped with CIM facility
and dynamic design programmes which
allow optimised designs for different
requirements.
We are abreast with latest international
standards and practices in material
handling. Renowned academic institutions
also help in upgrading the products.
FEM technique is used to design the
structures of the crane. Alongside is the
picture of the behaviour of the traverser
end-carriage with the application of load.
Gear Boxes
Gear boxes and couplings are the heart of any crane and are responsible
for the reliability factor. Reva therefore, chose to manufacture vital crane
components in house, ensuring their quality, compatibility and
serviceability. The gear unit use hardened helical gears in R 20 series,
which run silently with good lubrication and are vibration-free steel
fabricated stress relieved or graded cast iron housing. The gear units
have long life and are almost maintenance free. All gears, pinions in gear
boxes conform to DIN-8/AGMA-12 tolerances.
The design of gears and pinions is verified with the help of the software
from CMTI based on the Buckingham Method of Gear design.
The weight/power ratio is optimised by the use of case hardened low
carbon-alloy steel of high strength (58-62 HRC).
The gear reduction efficiency is as high as 99% per reduction.
Computer aided design based on Buckingham dynamic
load equation is adopted by Reva for pinions and
gears for compact and robust gear boxes with
safety factor > 1.25. The pinions are integral
with shafts for better strength characteristics
ensuring life of 40000 hours or more.
Couplings
Reva’s flexible geared couplings meets the
acceptance norms, set forth in
IPSS:1-01-005-86 specification followed the
Indian Steel Industry.
The couplings are known for the highest
possible torque transmission capability,
great mechanical flexibility and ease of
compensation for angular, parallel and axial
misalignments of connected shafts with minimum
power loss.
Gear Hubs and outer sleeves are manufactured from medium
carbon steel. The teeth are induction hardened to 30 HRC for
longer life and are generated by an involute system with 30 degree
pressure angle, making a quantum breakthrough in coupling design
and performance. The coupling parts and gears are interchangeable.

Travelling/Traversing and other mechanical engineering requirements which are
divided into 4 independent modules:
1) Shaft Mounted Gear Boxes in sizes TM 04, 06, 08, 10, 12, 16 to suit various motor rating and
output speed requirements with added features given below.
• The staggered and rationalised centre distances reduce the overall size and
reduce noise due to balancing of forces.
• The arrangement for mounting a torque arm is an integral part of these
gear machineries.
• The free-input shaft is an option to suit any international IEC motor frame size/
we also provide standard crane duty brake motors.
• The output gear shaft is either hollow ground to be keyed or solid shaft to be shrink
disc fitted with the required driven equipment.
2) Double flanged Rail Wheel assemblies of diameter 160mm to 500mm, in R-10 series,
are suitab le for travelling/traversing for varied sizes of rail and for different standardised
speeds.
3) Squirrel Cage motors from 0.18 to 25.0 KW are available. All squirrel cage motors are
standard motors with built-in disc brakes manufactured by an ISO:9001 company and
have C.E. marking also.
4) State of the art voltage variable frequency A.C drives are available for stepless speed control.
Gear Cases
Gear Cases are cast iron FG 200 or cast aluminium LM-6
duly shot peened, stress-relieved and machined on
up-to-date CNC manufacturing centres.

ground. The driving wheels have an extended axle to fit into
the hollow shaft of the travelling machinery with a key or
shrink disc.
Wheel Blocks
Wheel Blocks are fabricated from IS:2062 steels. These blocks are
accurately fabricated and machined to achieve required parallelism
and perpendicularity of the wheels. An adapter plate is provided for
welding of distance pieces to obtain required wheelbase. The distance
pieces can either be standard rolled channel iron or fabricated box or
tube depending on the design requirement. After fixing the distance
piece these wheel blocks become end-carriages for cranes or are used
for other mechanical engineering usage.
Eccentric Bush
An eccentric bush is provided in the wheel block for the purpose of
height adjustment of the wheel to the tune of 5mm. For eg, if some
particular wheel is not sitting properly on the rail, then with the help of
an eccentric bush the wheel can be lowered to make it sit on the rail.
Bearings
The moving axle in the wheel assemblies are mounted on amply rated
spherical roller bearings to give maintenance-free service for a long time.
Surface Finish
All wheel blocks and travelling machineries are epoxy coated to
make them suitable for indoor and outdoor application. All exposed
machined components are suitably protected from corrosion.

These cranes relieve the overhead cranes for
carrying out more useful work on the shop floor.
Being designed on through FEA, these are
extremely reliable & safe. These have standard
Reva Electric Wire Rope Hoist for lifting of
loads.
The cranes operate at a lower height than the overhead crane,
with the lift in the range of 3-5 metres. The lifting capacity could
be in the range of 0.5 tonnes to 10 tonnes. (Higher lifts and
capacities can also be supplied). The hoisting Speed could be
chosen from our standard 3mpm or any desired speeds
depending on application.
Jib cranes swivelling could be hand operated, but , electrically
operated cranes with electric wire rope hoists, are the order of
the day for increasing production. Rotational speeds of 0.5 rpm
are mostly desired, however can be designed as per your
requirements.
The Jib Cranes are very versatile in handling
material to and from machining bays, small part
assembly shops, hammer/press shops, repair
bays, etc. compared to overhead cranes, which are
meant for handling heavier and bulky material,
the jib cranes are very useful for faster operations.
Jib cranes require lesser investment than
overhead cranes. Apart from the capital cost, the
running and maintenance costs are less as jib
crane parameters can be optimised as per
job requirements
