TRAVELING MACHINERIES & WHEEL ASSEMBLIES

Travelling Machineries & Wheel Assemblies

Reva offers one of the finest available selection of energy efficient Travelling Machineries with built-in reliability, in-house manufactured components and optimal engineering using the latest designs, materials, manufacturing & quality assurance techniques. Keeping pace with technological advances in terms of modularisation and standardisation, Reva has developed a system of 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 CasesGear 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.

Gears & PinionsGears are designed in R-20 series. All gears and pinions manufactured from low carbon alloy steels are 100% Helical, Case Hardened & Profile Ground conforming to DIN-7 standard.

ShaftsOutput shafts of travelling machinery are manufactured from medium carbon alloy steels and are hardened and ground. All keys are as per DIN-6885.

WheelsWheels are manufactured from forged medium carbon alloy steel and are machined on up-to-date on CNC turning centres. The wheels are hardened to hardness of 26 HRC and axles, shrunk-fitted into the wheels, are also hardened and 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 BlocksWheel 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 BushAn 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.

BearingsThe moving axle in the wheel assemblies are mounted on amply rated spherical roller bearings to give maintenance-free service for a long time.

Surface FinishAll 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
