D28 series welding table with locking casters and adjustable legs
The D28 series welding table with locking casters and adjustable legs is a modular precision fixturing platform designed for welding, assembly, and inspection of heavy/large workpieces. Its core features include φ28mm standard positioning holes (D28 system) and a 100×100mm equidistant grid, combined with heavy-duty locking casters (for mobility) and precision adjustable legs (for leveling/fixing). This design balances mobility and operational stability, and is widely used in heavy-duty welding applications such as steel structures, construction machinery, automotive frames, and rail transit. It complies with CE/ISO safety and precision standards.

Core Features and Advantages
- D28 Heavy-Duty Positioning System: φ28mm large aperture + 100mm large spacing, providing stronger load capacity, suitable for large/heavy workpieces, compatible with global standard D28 fixtures, modular design for quick changeover, reducing tooling costs and changeover time.
- Mobile + Fixed Dual Mode: Heavy-duty locking casters enable quick movement within the workshop, and a one-button lock switches to a fixed workstation; adjustable legs provide precise leveling, solving uneven ground problems and ensuring welding accuracy and stability.
- High Rigidity + High Durability: HT300/Q355 base material + stress relief treatment, resistant to deformation and impact; nitrided/hardened surface, resistant to welding slag adhesion, wear-resistant and rust-proof, long service life, and low maintenance costs.
- CE Compliant + Precision Assurance: Complies with EU machinery safety standards, complete precision testing reports, suitable for export and high-end manufacturing scenarios; seamless splicing allows expansion into large welding production lines, suitable for multi-variety, small-batch/large-batch production.
- Multi-functional Integration: Optional features include pneumatic interfaces, welding slag collection troughs, fixture storage racks, grounding devices, tool carts, etc., improving operational efficiency and workshop cleanliness.

Comprehensive services for foreign trade procurement
- Accurate quotation service: Supports all international quotation terms such as FOB/CIF/EXW/DDP. Based on the customer's destination port and product specifications (including customized configurations), accurately calculates sea freight, customs duties, insurance fees, and provides detailed Chinese and English quotation sheets, indicating product specifications, configurations, fixture lists, certification documents, delivery dates, logistics details, and other information at a glance; Batch orders (≥ 5 units) can enjoy a 5% -15% discount.
- Heavy load logistics and packaging services: professional international heavy equipment logistics team selects the best logistics channel for customers (whole container/combined container shipping), adopts reinforced IPPC fumigation wooden box+multi-layer foam corner protection+waterproof film+rust proof paper, and adds additional steel belt reinforcement+wooden support for heavy models to prevent collision, corrosion and deformation during transportation; Provide a complete set of customs clearance documents including fumigation certificate, certificate of origin, bill of lading, commercial invoice, etc. along with the goods to ensure smooth customs clearance.
- Technical support and training services: Provide installation manuals, operation manuals, and maintenance manuals in both Chinese and English, equipped with a 24/7 online technical team in both languages to solve customer installation, debugging, fixture matching, troubleshooting, and other problems; For large batch orders (≥ 10 units), professional technicians can be arranged to come on-site for installation, debugging, and operation training (overseas customers will charge transportation/labor fees according to the actual situation), explaining core knowledge such as heavy-duty movement/fixed switching, table leveling, fixture matching, and daily maintenance.
- Lifetime after-sales support service: providing lifelong technical guidance, even if the warranty period has expired, we will still answer technical questions for customers free of charge; When the equipment malfunctions severely, it is supported to return to the factory for repair and bear the repair and processing costs. Customers only need to bear the round-trip transportation costs; D28 fixtures, casters, legs and other accessories are supplied at a lifetime affordable price, with no problem of later parts supply interruption, solving customers' worries.
