Description of Overhead Travelling Crane
Single Girder Electric Overhead Cranes (SGEOTCs) are electric cranes that consist of usually one monorail hoist mounted underneath a single girder, usually either an I-beam or box girder. They generally cater for relatively smaller loads of up to 12.5 tones and spans of within 30 meters. The entire crane travels on a runway beam installed directly onto the building columns via corbels or on its own column. Standard SGEOTCs have 6 axes of motion: up & down (hoisting), left & right along the girder (cross travel), and forward backward along the runways (long travel).
Our SGEOTCs can handle most standard industrial material handling needs and have found service in a wide and diverse set of industries, such as:
Steel and hardware distribution industry
Warehousing
Machining stations
Engineering fabrication shops
Equipment servicing workshops
Maintenance and servicing crane
Automotive and commercial vehicle industry
Aerospace industry
SGEOTCs can be designed to various capacities, heights, and spans to suit your needs.
Our wire rope hoists utilize extra high strength galvanized wire rope, with multiple times factor of safety to meet and exceed requirements established by the European FEM.

Detailed Configuration of Suspension Overhead Travelling Crane
Motor:
Hoist Motor is a taper type rotor motor with braking, it is made by Nanjing special motor factory, it is of the best quality motors,it has bigger torque, so it can be adapted to moving frequently, the Maximum torque is 2.4-3 times than the rated torque.
Gear Box:
Hoist Gear Box has specially treated gears for high wear resistance. Each Geared Shaft assembly is supported on ball or roller bearings, to ensure smooth, low-friction operation.
Wire Rope:
Hoisting ropes comply with the exporting standards. The leading rope taken by the Drum does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six.
Rope Drum:
Grooved Drum, seamless pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided. Drum Shaft resolves on Ball Bearings for ensuring smooth running.
Electric apparatus
controlling system:
Model CD 1 and MD 1 is composed of the contactor box, controlling switch, cut-off limiter, the working voltage of controlling switch is 380V, 36V or 24V(safety voltage).
Rope Guide:
Rope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may not uncoil even when the Hoist is in unloaded condition. The rope guides of our company is thickened and dilated, so that it is not easy to be damaged.
Hook:
The Hook Block is tested to 150 % of full load before assembly. The rope sheaves are fully guarded with protective steel casting. All sheaves rotate on ball bearing the pulley is thicken and dilated than domestic common pulley.
