Product and Company FAQS

The Onchtech 3-ton tracked spider crane is only 0.8 m wide and can theoretically pass through access routes at least 0.8 m wide. Additional clearance is recommended for turns, slopes, obstacles, crawler travel, and on-site safety.

When the lifting radius increases, the load creates greater overturning moment, so the allowable lifting capacity must decrease to maintain stability. Actual capacity depends on working conditions, outrigger status, and the load chart. Onchtech recommends technical confirmation before operation.

Learn which overseas safety certifications Onchtech machinery supports, including CE, ANSI, and CSA compliance, plus EN280 and EN474 standards, compliance nameplates, and documents for smooth market entry.

Learn where Onchtech construction machinery is exported, including Europe, South America and Southeast Asia, and how verified local project feedback supports supplier evaluation.

Learn how Onchtech equipment helps rental businesses reduce downtime, lower maintenance costs, improve utilization, and shorten investment payback periods.

Onchtech recommends electric power or a diesel-electric dual-power configuration for spider cranes. Electric drive is preferred for indoor, factory, low-emission, and noise-sensitive environments, while dual power improves adaptability for outdoor transfers and complex working conditions. Diesel engines should comply with EU Stage V or EPA emission standards.

The two-section telescopic outriggers of this 5-ton spider crane have a maximum extension of approximately 5800 mm. Actual space requirements should be confirmed based on lifting weight, working radius, ground conditions, and site obstacles. Onchtech recommends a site assessment before project use.

Before purchasing an Onchtech spider crane, provide the total weight of the load and rigging, actual working radius, lifting height, access and doorway dimensions, ground or floor load capacity, slope, outrigger deployment area, operating environment, required configuration, project location, and planned start date. This information helps assess equipment access, support, and lifting feasibility.

Onchtech explains that spider cranes feature a compact body and crawler mobility for indoor, confined, and complex lifting sites, while truck cranes are generally suited to locations with better road access and more open working space. Selection should consider load, lifting radius, ground conditions, and site access.

Learn how Onchtech LiFePO4 batteries deliver an 8–10-year design life and support reliable charging and discharging at temperatures as low as -20°C.

Learn why Onchtech machinery costs slightly more than low-end Chinese alternatives but remains more affordable than leading European and American brands, delivering stronger durability, residual value, and overall ROI.
