China Best Famous Varibloc Gear Reduction Manufacturers - crane gearbox – Intech

Product Description

There are hoist reducers and travel reducers in cranes. Hoist reducer is a key transmission equipment of the hoist cranes. Travel reducer is a key transmission equipment of the long travel and cross travel on crane structures, which is also a core part of all kinds of cranes like metallurgical cranes, bridge cranes, gantry cranes, dry quenching cranes, nuclear plant cranes. Our star products (520t casting cranes, 1300t bridge cranes, 900t gantry cranes) have the advantages like advanced structure, heavy load, high reliability.

Increases in productivity and lifting capacity require a fresh look at the hoist and wheel drive gearboxes of your cranes. INTECH specializes in developing newly designed crane gearboxes from your drawings or by reverse engineering your existing gearbox. Our engineering team stands ready to evaluate your current gearbox and provide a solution to improve its performance.

Cranes gearboxes are an excellent application for INTECH carburized and hardened gearing. INTECH gearing provides additional load capability in your existing gearbox housing through improvements in the gear metallurgy and quality. Our design and manufacturing approach will increase the strength and durability of your crane gearing, thereby increasing the service capability of your crane.

For new or reconditioned gearboxes for your crane applications, contact an INTECH representative today to learn all INTECH has to offer.

Specification:

Feature

1. carbon constructional steel, carbon constructional quality steel, low-alloy steel.

2. It has good rigidity , resistance to impact ,transmitting large torque and run-stop frequently.

3. The gearbox features compact structure, light weight, small volume, high ability of load ,low noise and vibration

4. The gearbox can achieve test of temperature and vibration automatically.

5. The gear is manufactured by high-quality alloy steel with carburizing and quenching. The tooth surface hardness is HRC57+4.The gear is modified with serrated form .The class of precision is 5～6.The material of cutting edge: 4Cr5WMoVSi

6. The case s structural style is horizontal split structure which is combined with high intensity bolt , which is manufactured conveniently and fine appearance. The case is welded manufactured which is annealed after welding .The case will be dealt with aging treatment in order to eliminate residual stress. So, the case deforms hardly .

7. The gearbox adopts mechanical sealing, which has good effect. It’s sealing structure is reliable and non-maintaining .

8. The gearbox uses forced spray oil lubrication, the lubrication pipelines is distributed in or out of the gearbox, which can lubricate the gear and bearing sufficiently. The oil inlet and the oil discharge mouth are mounted on the gearbox .The pressure switch, the flux monitor and the cut-off valve are mounted near the oil inlet. The pressure switch and the flux monitor can monitor the oil supply and feed back the pressure and flux signal which is switch quantity or analog quantity to primary control system.
