Crane capacity upgradation can save over 50% of cost as compared to replacement of existing crane by new. However, Crane upgradation needs high degree of understanding of crane design and analytical ability to carry out accurate reverse engineering. In most of the cases manufacturing drawings of existing crane are not available with the crane user and in such a situation detailed study of existing crane is essential to determine its suitability for capacity/ span upgradation. Study of Crane Operation to determine duty cycle, Crane audit, Visual observation, dimensional verification, NDT testing of plates to determine residual thickness of load bearing structures, measurement of speeds of Hoist, CT and LT motions, measurement of motor currents, measurement of crane girder deflection under load and analysis of structures using computerised software such as STAAD & ANSYS are some of the technique that we employ to determine whether the crane is suitable for upgradation. We also undertake upgradation of complete electrical system of crane. This may include replacement of slipring motors by Sq Cage motors with VVVF Control, provision of compact festoon cable system / drag chain in place of open wire system for trolley power supply, replacement of Angle Type DSL / open wire DSL by Shrouded Bus bars, Changing of Electrical Cables and Installation of Electronic Load weighing system/ Overload limiter on Crane. Our design team has hands on experience of designing cranes for wide range of application ranging from Workshop duty, Power Plant, Cement Plant, General Engineering to Steel Mill duty. Our team has designed Ladle Handling Cranes, Magnet Cranes, Grab Bucket Cranes, Tong Cranes, Rotating Beam Crane up to 500 MT Capacity. Our head of Design has more than 40 years of experience in Design of EOT and Gantry Cranes.

• capacityup to 250 MT

Double girder cranes are rugged in construction and find their use in a wide range of hoisting capacities and applications. The promoters of Aditya Cranes have experience of designing cranes up to 500 MT capacity.Double girder EOT crane find their application in power plant, workshop duty, transformer industry, cable industry, process plants, steel plants, coal fields, cement plants, engineering industry to just name a few.

• capacity ranging0.5 MT to 5 MT

Aditya make Pillar mounted (Free Standing) Jib Cranes are best suited for work station application. These cranes are directly installed on shop floor without any need for support from building column. Available in capacity ranging from 0.5 MT to 5 MT and outreach of 8 meters, these cranes serve the need of local station without use of shop EOT Crane.

• capacities ranging125 kgs to 2,000 kgs

Lightweight portable gantries are available to meet needs of warehouse and small workshops. These cranes can be easily dismantled and transported to another location in a truck. The portable gantry crane is provided with solid rubber or rubber tyred caster wheels that move on warehouse floor. The gantry can be easily pushed manually at desired location. The portable gantry crane is available in capacities ranging from 125 kgs to 2, 000 kgs with a span up to 5 meters. These cranes are best suitable for light duty application and are much more economical than permanent shop cranes.

Aditya make Single Girder cranes are modular in construction using standard wire rope hoist. Compact and light weight design ensures lower building space, most optimum utilization of floor space and lower building loads.Light Weight and compact construction minimizing building loads and space saving.

The Under slung single girder crane is very similar to overhead travelling crane except for the fact that the end carriages are hung below the gantry girders made of I section.The Crane’s end carriages are hung below the shop I Beam. The Long travel wheels move on the beam flanges and the beam girder is supported below the end carriages.The Under Slung Cranes can also be supplied with overhang (girder extending beyond crane span) on one side or both the sides as per the requirement of customer.
