Overhead Cranes | Lifting Systems
We deal in Overhead Cranes like Single Girder Overhead Crane, Double Girder Overhead Crane, Jib Overhead Cranes, Gantry Overhead Crane and Semi-Gantry Overhead Cranes. We specialize in Designing, Manufacturing, Installation and Maintenance of Overhead Cranes. We follow the CMAA & ASME standards for the Designing, Manufacturing, Installation and Maintenance of Overhead Crane. Overhead Cranes are of different duties ranging from 1 hour operating time to 16 hour with variable & constant load conditions. We know your requirements according to your process and nature of work. Single Girder Overhead Crane Single Girder Overhead Crane consists of bridge fitted on two end carriages. The end carriages are fitted with wheels that travel on the rail by motors. The hoist is under hung on the bridge and a control pendent is attached to the hoist for the cross and transverse motion of crane. The hoist reeving is 2/1 or 4/1 depending on the duty of overhead crane. The power supply is single phase or 3 phases depending on the duty and capacity of the overhead crane used. The electrical system consists of PVC Bus bar and Festoon system attached to the bridge. We have single girder overhead cranes ranges from 250 kg to 15000 kg with lifting height from 4 m to 18m with different overhead crane duties. Double Girder Overhead Crane Double Girder Overhead Crane consists of two girders mounted on two or four end carriages depending upon the duty of the overhead crane. The end carriages are fitted with wheels that travel on the rail by LT motors. The hoist is mounted on the trolley that travel on the upper sides of bridges on a square bar or rail. The power supply is single phase or 3 phases depending on the duty and capacity of the crane used. The electrical system consists of PVC Bus bar and Festoon system attached to the bridge. We have single girder overhead crane ranges from 5000 kg to 50000 kg with lifting height from 4 m to 18m with different overhead crane duties. 1

Gantry Overhead Crane The Gantry Overhead Crane may be single girder or double girder depends upon the capacity and duty of the overhead crane. The bridge of gantry overhead crane installed on its four pillars and the pillars are attached with the end carriages that move with the bridge on the rail. The rail is fitted on the floor level. The power supply may be single phase or 3 phase depending upon the duty of the crane. The electrical system consists of cable reeling drum and Festoon system attached to the bridge. We have different capacities of gantry overhead cranes ranges from 500 kg to 100000 kg with different overhead crane duties. Semi Gantry Overhead Crane Semi Gantry Overhead Crane is a combination of both girder crane and gantry crane. One end carriage of the crane is move on the floor and other end carriage is move on the gantry bridge. The power supply may be single phase or three phases depending upon the duty of the overhead crane. The electrical system consists of cable reeling drum or PVC bus bar system and Festoon system attached to the bridge. Any electrical system can be use for the long travel of the overhead crane. We have different capacities of semi gantry overhead cranes ranges from 250 kg to 50000 kg with different overhead crane duties. Pillar Mounted Jib Overhead Crane The Jib Overhead Crane is the form of cantilever beam system. The pillar mounted jib overhead crane installed on solid foundation design to bear the load of overhead crane. The jib overhead crane is also called a slewing crane. The power supply may be single phase or three phases depending upon the duty of the overhead crane. The electrical system consists of Festoon system attached to the jib arm. We have different capacities of jib overhead crane range from 150 kg to 10000 kg that rotate about 330 to 180 Degree about it axis 2

and arm length may be 2 m to 8 m with different overhead crane duties. Wall Mounted Jib Overhead Crane The Jib Overhead Crane is the form of cantilever beam system. The wall mounted jib overhead crane installed on side wall or concrete column with bolts. The jib overhead crane is also called a slewing crane.. The power supply may be single phase or three phases depending upon the duty of the overhead crane. The electrical system consists of Festoon system attached to the jib arm. We have different capacities of jib crane range from 150 kg to 10000 kg that rotate about 180 degree about it axis and arm length may be 2 m to 8 m with different overhead crane duties.
