When lifting work must be completed inside a building, within a narrow access route, or on uneven ground, conventional cranes may be difficult to transport, position, or deploy. A 1.2-ton spider crane is a compact tracked lifting solution designed for these restricted-access conditions.
The Onchtech 1.2-ton spider crane combines a compact body, rubber tracks, telescopic boom and independently adjustable outriggers to support lifting, installation, transfer and maintenance work where space is limited. It is intended for professional B2B users who need a practical micro crawler crane for controlled, small-to-medium lifting tasks.
Spider cranes are particularly relevant when a project requires lifting capacity but does not have the access, open working area, or ground conditions required by larger truck cranes or conventional lifting equipment. Their application suitability should always be evaluated against the actual load, lifting radius, ground condition, access route and site safety requirements.
Suitable for moving, positioning or installing equipment inside factories, workshops and other indoor facilities where access corridors and operating areas are constrained. The compact format helps the crane enter areas that may be inaccessible to larger lifting machinery.
Applicable to controlled lifting and positioning tasks for curtain wall installation, especially where a compact lifting unit is needed near building interiors, courtyards or restricted construction zones.
Can support lifting work associated with exterior maintenance, high-level equipment handling and repair activities where the working area is too narrow for conventional cranes to set up efficiently.
Relevant for building-floor or rooftop projects involving equipment transfer and installation, subject to confirmation of access conditions, floor loading limits and the planned lifting arrangement.
A compact crawler crane can be considered for installation, maintenance and material-handling tasks at substations and power facilities where site access and operating space require careful equipment selection.
Designed for projects in narrow courtyards, internal passages, limited construction areas and other confined spaces where maneuverability is as important as lifting capability.
The tracked undercarriage and independently adjustable outriggers support deployment on steps, slopes and uneven surfaces. Site assessment remains essential before lifting operations begin.
A 1.2-ton spider crane is not a substitute for heavy-duty lifting equipment. It is best suited to applications that require compact access and precise deployment within its approved operating envelope. Before selecting equipment, project teams should confirm the following factors:
| Assessment Item | Why It Matters |
|---|---|
| Load weight and dimensions | The lifted load must remain within the rated capacity for the planned configuration and operation. |
| Lifting radius and required height | Capacity and working capability depend on the operating radius, boom position and project lifting requirements. |
| Access route | Doorways, elevators, corridors, turns and height restrictions should be checked before site delivery. |
| Ground and support conditions | The surface must be evaluated for levelness, bearing capacity and safe outrigger deployment. |
| Required configuration | Options such as wireless remote control or a moment limiter should be selected according to the operating plan and applicable requirements. |
This micro crawler crane is intended for small-to-medium lifting and precision installation work, not lifting beyond its rated capability. Actual lifting capacity, working radius, configuration and suitability must be confirmed according to the specific jobsite, load, ground condition and operating requirements. Lifting work should be planned and performed by appropriately qualified personnel in accordance with applicable local regulations and site procedures.
