Product Details
Crawler Spider Crane ｜ 12‑Ton Class
Heavy‑Lift Equipment for Confined Spaces and Complex Terrain
The Onchtech 12‑ton crawler spider crane is an ultra‑compact industrial micro mobile lifting device engineered for extreme heavy loads and complex high‑altitude environments. It is available with engines from Yunnei, Yuchai, Yanmar, Deutz, and Cummins, meeting Euro V and EPA emission standards. The machine combines a compact body, telescopic boom, crawler undercarriage, and composite outriggers, making it suitable for steel structure installation in large industrial plants, high‑rise floor or rooftop lifting, substation construction, and bridge maintenance projects that require equipment to reach core work areas. For buyers facing restricted access for conventional large cranes, uneven ground conditions, or the need to balance working radius and support conditions, this crane offers a 12‑ton heavy‑lift configuration option.This product is CE certified.
Core Performance and Key Structure
Customizable Power System & Hydraulic Transmission: Available with engines from Yunnei, Yuchai, Yanmar, Deutz, and Cummins. The powerful system with efficient hydraulic transmission supports lifting operations and micro‑movement control, suitable for installation and positioning tasks requiring fine adjustments.
5‑Section Telescopic Boom: The 5 m × 5‑section high‑strength manganese steel telescopic boom provides a maximum above‑ground lifting height of 21 m and a maximum working radius of 19 m, offering reference coverage for lifting points on floors, rooftops, and around obstacles. Actual capacity should be verified against load charts for specific working conditions.
Compact Crawler Travel Structure: With an overall width of approximately 1.86 m and 400 mm wide steel tracks, the undercarriage enables access to restricted passages, uneven ground, and areas beyond the reach of conventional large cranes. Pre‑entry verification of clear width, bearing capacity, and turning radius is required.
Operation, Safety, and Configuration Adaptation
Composite Outrigger System Combining manual swing‑out, hydraulic extension, and hydraulic support, with a maximum span of 7600 mm, enabling support deployment on slopes, steps, and other site conditions. Site assessment of ground bearing capacity, slope, and outrigger deployment space is required before setup.
Standard Operating Configuration Equipped with safety interlock design and an intuitive control panel for easy monitoring and execution of lifting movements; suitable for conventional work organization requiring close observation of loads and work positions.
Optional & Custom Content Wireless remote control, load‑moment indicator, work basket, and hydraulic jib are optional and not included in the standard configuration. Onchtech can discuss adaptation solutions based on project control methods, attachment needs, colors, branding, and OEM/ODM/OBM requirements.
Typical Applications
Industrial Steel Structure Installation: Lifting steel components and electromechanical equipment inside factory buildings or densely equipped areas; the compact crawler body helps access restricted passages and approach installation points.
High‑Rise Floor & Rooftop Lifting: Used to lift heavy components or equipment to designated positions on floors and roofs; the boom's lifting height and working radius cover certain overhead installation tasks.
Substation & Power Engineering: Performing component installation or maintenance lifting around equipment foundations and structures; micro‑movement control is suitable for tasks requiring fine positioning.
Bridge, Municipal Road, & Dam Maintenance: In maintenance areas with site boundaries, elevation changes, or restricted access paths, equipment positioning can be planned using crawler travel and outrigger deployment.
