Buy & Import Crane Duty Helical Gearboxes from Hangzhou Starred-River Machinery Co., Ltd. - Wholesale Supply

The Crane Duty Helical Gearboxes are engineered for crane mechanisms and are also suitable for transport, metallurgy, mining, chemical and light‑industry equipment. Gears and bearings are made from 20CrMnTi, 40Cr and 42CrMo steels and are hardened to 58‑62 HRC (217‑255 HB) through a carburizing and quenching process. The product line offers nominal speed ratios from 10 to 200 across single‑stage to three‑stage configurations, providing flexibility for different torque requirements. The design includes a compact size and reduced overall height to meet crane agency specifications.

In the broader gear industry, helical gearboxes of this class typically achieve mechanical efficiencies between 94 % and 96 % and operate with low noise levels. The use of forged and tempered 42CrMo and 35CrMo shafts extends service life, while the gear circumferential velocity is limited to 20 m/s and the high‑speed shaft speed to 1500 r/min. The units tolerate ambient temperatures from - 40 °C to 45 °C and can run in both forward and reverse directions, matching standard crane operating conditions.

Typical buyers include original equipment manufacturers and system integrators that require reliable transmission in heavy‑duty cranes and related machinery. The gearboxes are packed in wooden cases and shipped from Shanghai or Ningbo ports, with delivery scheduled within 25‑35 working days after full payment is received. The supplier can produce up to 3000 sets per month and offers a one‑year warranty together with post‑sale technical support.

Frequently Asked Questions About Crane Duty Helical Gearboxes from Hangzhou Starred-River Machinery Co., Ltd.
The gears are manufactured from 20CrMnTi, 40Cr and 42CrMo steel, while the bearings use compatible steel grades. These grades are chosen for their wear resistance and strength in crane applications.

Sourcing Crane Duty Helical Gearboxes from Hangzhou Starred-River Machinery Co., Ltd. - China Import Guide

Before placing an order, verify the material grades (20CrMnTi, 40Cr, 42CrMo) and the hardness range of 58 - 62 HRC with the supplier. Request the latest ISO certificate and any material test reports to confirm compliance with your project specifications. Confirm that the gearbox dimensions and centre distance (560 mm nominal) match your design drawings.

Logistics should be clarified early: the supplier states a delivery window of 25‑35 working days after full payment, with loading from Shanghai or Ningbo ports on an FOB basis. Discuss the preferred Incoterms, payment schedule and any required customs documentation before confirming the contract. The monthly capacity of 3000 sets allows for sizable orders, but ensure your order quantity fits within their production plan.

Arrange for a pre‑shipment inspection by a recognised third‑party agency to check gear geometry, hardness and heat‑treatment records. Request the heat‑treatment certificate, material test report and a one‑year warranty document as part of the final paperwork. These steps will help guarantee that the delivered gearboxes meet the required performance and quality standards.
