Import Double Beam Crane — Buy in Bulk from Supplier in China

The double beam crane from SMF Heavy Industry (Suzhou) Co., Ltd. is a QD model overhead crane with lifting capacities ranging from 5 to 50/10 tonnes, designed for heavy-duty workshop and warehouse operations. It features a welded steel main beam structure, bridge, trolley, running gear, and electrical systems, with working classes A5 and A6 based on load frequency and duty cycle. The crane is configured for side, end, or top cab entry, with the operator cabin typically mounted at the left end as shown in the provided diagrams.

The main beam is constructed from thick steel plates welded into a box-type profile, which is prone to deformation under dynamic loads. SMF’s engineering analysis used finite element modeling to optimize the beam’s geometry, resulting in a design that improves strength by 38.7% and stiffness by 33.9% compared to the original structure. This reinforcement method is specific to their design process and addresses known fatigue issues in thin-walled crane beams under repeated cyclic loading.

This crane is used in industrial settings requiring precise, high-capacity material handling, including manufacturing plants, steel yards, and logistics centers. Buyers typically require compliance with A5 or A6 duty ratings and safe electrical conduction via slide wire or angle iron, installed either alongside or opposite the cab. Packaging is in plywood cases for sea freight, and trade terms are FOB from Shanghai or Ningbo ports, with lead times confirmed directly with the supplier.

SMF Heavy Industry (Suzhou) Co., Ltd. is based in Kunshan, Jiangsu, with a manufacturing address at No. 21, East Chaoying Road. The company is classified as an imported supplier with harbor trust tier, indicating verified export history. The listing does not state years in operation, employee count, or certified quality systems. Their technical documentation shows engineering analysis of crane beam deformation, suggesting in-house design capability rather than pure assembly.

The supplier does not claim ISO certification, export volume, or client names. Their focus appears to be on structural optimization of crane beams using finite element simulation, as evidenced in the product description. No information is provided about after-sales service, spare parts availability, or installation support. Buyers should confirm these details directly with the supplier before placing orders.
