SummaryXuzhou Bob-Lift Construction Machinery Co., Ltd. is a China-based manufacturing factory established in 2013, with 165 employees and a reported manufacturing area of 40,000 m². It specializes in truck-mounted, knuckle-boom, telescopic-boom, marine, port, forestry, and related cranes. The supplier reports ISO9001:2008 certification, more than 10 production lines, 8 years of R&D engineer experience, and 6–10 quality-control staff. It has self-operated import and export rights, began exporting in 2013, and derives 41%–50% of sales from exports. The company mentions maintenance sites in some countries, but the locations and service scope are not specified. Available customer evidence identifies one buyer with four recorded transactions, indicating some transaction history but limited breadth. Financial information is insufficient for a reliable credibility assessment.

Supplier typeThe supplier is explicitly identified as a factory and limited company in Xuzhou, China, specializing in the design, manufacture, and sale of truck-mounted cranes. Its stated industry is manufacturing, supporting classification as a direct manufacturer rather than only a trading intermediary.

CertificationsThe supplier reports holding an ISO9001:2008 management-system certificate. This is explicit evidence of certification, although the slices do not provide its validity period, issuing body, or any additional certifications.

After-Sales capabilityThe company states that it has established maintenance sites in some countries, indicating an overseas after-sales service presence. However, no countries, staffing, response arrangements, spare-parts capability, or service coverage details are provided.

R&D capabilityThe supplier describes itself as a private high-tech enterprise and reports 8 years of R&D engineer experience. Its broad crane product range and stated design capability support some R&D capacity, but no patents, new-product achievements, testing capability, or R&D team size is provided.

Production capacityThe supplier reports a 40,000 m² manufacturing plant, more than 10 production lines, and annual production output in the stated range. Its product specialization and manufacturing description further support established production capability for construction machinery.

Client casesThe available trade records identify ТОО KBK ALMATY HOLDING as a buyer across four transactions. This provides evidence of at least one customer relationship and export transaction history, but the customer base shown is narrow and no project details, product descriptions, repeat-order evidence, or customer evaluations are supplied.
