Reinforced steel body for high load capacity - Original design with SGCC galvanized steel plate and SPCC cold-rolled plate surface finished with powder coating to enhance durability and rigidity. Long-life pulley bearings - Pulley bearings use stainless steel components and a strong elastic spring, consisting of 20% steel clamps, designed to withstand repeated high-strength operations. Three-stage locking construction with roller bearings - Three-stage locking mechanism paired with roller bearings provides secure positioning and smooth, reliable movement. Enhanced safety and high temperature resilience - The SGCC galvanized plate and SPCC cold-rolled surface, combined with powder coating, offer improved safety features, including explosion-proof capability and resistance to high temperatures. Key benefits - Robust construction supports heavy loads in demanding environments. - Durable, low-maintenance components extend service life. - Secure locking and smooth operation reduce setup time and misalignment. - Safety-focused design suitable for intense or high-temperature settings. Materials and compatibility - Steel body: SGCC galvanized plate; surface: SPCC cold-rolled plate with powder coating. - Bearings: stainless steel roller bearings. - Spring and clamps: high-strength elastic components including 20% steel clamps. Applications and use scenarios - Belt pulley installation and alignment in manufacturing lines or mechanical workshops. - Maintenance, inspection, and assembly of heavy equipment requiring stable, repeatable positioning. - High-temperature or safety-conscious environments where explosion-proof and fire-resistant characteristics are beneficial.
