Product and Company FAQS

Calculate the maximum combined weight of personnel, personal protective equipment, tools and materials on the platform, allowing a margin. The Onchtech SSL-16RT has a rated capacity of 680 kg and accommodates up to 4 people; both limits must be met. Check the manual for the extension platform’s separate load limit.

The Onchtech NC10003 offers all-electric, zero-emission operation, low noise, an 850 mm-wide body and a tracked chassis for challenging terrain and confined sites. It supports wireless remote control up to 150 m and manual driving, with a rated carrying capacity of 1 tonne, a lifting capacity of 0.5 tonnes and an unloading height of up to 1.5 m for transferring materials into trucks or hoppers.

Onchtech explains that platform height is the maximum elevation of the platform itself, while working height is the approximate height an operator can reach while standing on it. For the SSL-10HD, platform height is 10 m and maximum working height is 12 m.

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.

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.
