Supplier typeThe supplier is explicitly identified as a trading company and limited company, established in China in 2016, with six employees. Its stated product focus is used concrete pump trucks and parts, supported by broader machinery sales and related service activities.

After-Sales capabilityThe supplier states that its technology engineer provides technical support for production and after-sales service, and its business scope includes electrical-equipment repair and machinery-related services. This supports the existence of some after-sales capability, although the small team size and absence of detailed service resources limit the strength of the assessment.

R&D capabilityThe supplier has one R&D engineer responsible for customer-request confirmation, new-product design, and technical support. However, it reported no new products in the past year and no ODM, popular-brand OEM, or SDK capability, indicating limited demonstrated innovation output and service breadth.

Customization capabilityThe supplier explicitly offers customization from samples and designs. Its single technology engineer is responsible for confirming customer requirements and designing new products, directly supporting customization capability despite limited documented engineering capacity.
