Design
CRANOIST electric overhead traveling cranes are designed & manufactured accordance with IS 807, IS 3177, code of practice for design, manufacturing, erection, testing of structural part of the crane and IS 3177 code of practice for design of overhead traveling crane. In the design of components adequate factors of safety as per relevant code is allowed impact, fatigue, wear and stress concentration factors are taken whenever applicable. All drives are designed to give sound & efficient performance.
Bridge Girder
The bridge girder is fabricated from RSJ / Box type construction in the manufacturing. The maximum deflection of the bridge girder is limited to span / 1000 of the live loads. Bridge girder designed to sustain stress creating due to vertical & cateral forces with impact.
Hoisting Machine
The hoisting machinery / crab is designed with IS 3938 in modular construction which simplifies repair & maintenance consist of a CRANOIST heavy duty industries type std. wire rope hoist.
Controls
- The crane is controlled from pendent push button station is suspended from one end of bridge at a suitable height from the floor level with stepped down voltage of 110v, 24v.
- Dust proof powder coated sheet – metal housing consists of contactors overload relays fuses, transformers etc.
- Emergency stop button in all cranes to shutting of the power to the main connectors.
- The motors used are specially crane duty suitable for frequent starting, reversing and braking in accordance with IS 225.
- All trolley are drive motors have suitable AC / DC / brakes as std. equipments with smooth running properties.
