Key Selection Parameters to Confirm Before Purchasing a Spider Crane
ONCHTECH · Tracked Spider Crane Solution
In narrow construction zones, complex terrain, or heavy-duty operations at height, the nominal lifting capacity should not be the sole consideration when purchasing spider cranes. Actual selection should be based on a combination of factors.Operating radius, head, site accessibility, outrigger deployment space, ground bearing capacity, and safety configurationPerform a system judgment.Onchtech 12-ton spider craneFor engineering projects that require both tight traffic flow and heavy-duty lifting, this provides project purchasers, equipment rental companies, and professional contractors with options for equipment selection that can be further technically evaluated.
Compact heavy-duty lifting equipment for constrained working conditions
The Onchtech 12-ton tracked spider crane is an industrial-grade mini mobile lifting machine suitable for confined spaces where large lifting equipment cannot access, as well as construction areas with complex terrain. The machine features a tracked chassis and telescopic boom structure, supporting the planning and execution of heavy-duty lifting tasks within a compact overall layout.
The equipment is equipped with a Yunnei 76kW power system and hydraulic transmission system, and features...5-meter x 5-section high-strength manganese steel telescopic boomAccording to the equipment specifications, the machine weighs approximately 12.5 tons, has a width of approximately 1.86 meters, a maximum ground lifting height of 21 meters, and a maximum operating radius of 19 meters. The specific lifting capacity must be confirmed based on the actual operating radius, boom length, outrigger condition, ground conditions, and the corresponding load table; product name or a single parameter cannot replace the assessment of project operating conditions.
What parameters should be carefully confirmed before purchasing a spider crane?
For heavy-duty lifting projects in confined spaces and complex terrain, it is recommended to establish a basic evaluation framework based on the following dimensions before requesting quotations, comparing solutions, and providing technical briefings:
| Evaluation Dimensions | Core content to be confirmed | Key points for judging project suitability |
|---|---|---|
| Lifting Capacity and Load Table | Lifting weight, weight of lifting tools and auxiliary equipment, and allowable lifting capacity at different amplitudes. | The key is to verify the actual liftable load under the target radius and target height, and leave a reasonable operating margin. |
| Operating radius and head | The horizontal distance from the lifting point to the landing point, the height of obstacles, the installation elevation, and the coverage area of the boom. | The equipment data shows a maximum operating radius of 19m and a maximum ground lifting head of 21m; the actual operating conditions should be verified according to the path and load table. |
| Overall dimensions and access conditions | Clear width of transport channels, doorway dimensions, floor entrances, turning spaces, and access routes. | The machine is approximately 1.86m wide and can be used to assess access conditions in narrow passages; site obstacles, slopes, and turning margins should also be considered. |
| Tracked chassis and terrain adaptability | Track width, ground condition, ramps, steps, soft soil areas, and ground bearing capacity. | The 400mm wide steel track chassis helps with traversing complex terrain; however, the foundation bearing capacity, slope, and anti-settlement measures still need to be confirmed on site. |
| Outrigger deployment and support conditions | Outrigger type, maximum deployment range, outrigger landing point, pad arrangement, and surrounding clearance. | The equipment uses a combination of manually rotating, hydraulically telescopic, and hydraulically supported outriggers, with a maximum extension range of 7600mm; it should be verified whether the site has the conditions for complete or limited deployment. |
| Control and safety features | Requirements for operating visibility, micro-motion control, torque monitoring, remote control, and work area management. | The suitability of optional configurations such as wireless remote control, torque display, suspended platform and hydraulic boom can be evaluated according to project requirements. |
Equipment Structure and Key Points for Project Evaluation
Compact body, focus on approach path
For operations inside factory buildings, on floors, rooftops, or around existing facilities, the primary condition is whether the equipment can reach the lifting position. In addition to the overall width of the machine, the dimensions of the transport configuration, passageway corners, doorway heights, ground obstacles, and on-site organization routes should also be checked.
Tracked travel, focusing on ground foundation
Tracked structures are suitable for operations that require traversing rugged or uneven terrain, but this does not mean that site assessment can be ignored. Ground load-bearing capacity, slope, underground facilities, edge areas, and outrigger pad designs should all be taken into account in the lifting plan.
Hydraulic control, focusing on working condition matching
Hydraulic transmission and micro-motion control capabilities can be used in hoisting operations that require precise positioning. For tasks such as high-altitude installation and equipment relocation, qualified operators should perform the work in accordance with load, line of sight, wind conditions, and operating procedures.
Typical application directions
Based on its compact tracked chassis, telescopic boom, and outrigger support structure, the Onchtech 12-ton spider crane is a viable equipment evaluation option for the following projects:
- Steel structure installation and equipment hoisting in large industrial plants;
- Heavy component transportation and installation in restricted areas such as floors and roofs of high-rise buildings;
- Lifting coordination in the construction of large substations and power projects;
- Engineering operations that are subject to terrain or spatial constraints, such as the construction of municipal roads, dams, and bridge maintenance.
The actual application scope should be based on the project site conditions, work plan, equipment technical data and relevant safety requirements.
Recommended project information to prepare before technical communication
To improve equipment matching and technical communication efficiency, the purchaser or leasing operator can prepare the following information in advance:
- Lifting object:Single piece weight, dimensions, center of gravity, lifting points and lifting equipment requirements;
- Work location:The height and horizontal distance between the lifting and lowering points, obstacles, and turning space;
- Entry requirements:Net dimensions of roads, doorways, passageways, ramps, ground materials, and foundation bearing capacity;
- Supporting conditions:Outrigger deployment area, outrigger landing point, underground pipeline or edge risks, and pad arrangement;
- Safety and operational requirements:Operating methods, line of sight requirements, on-site wind conditions, work permits, and applicable project specifications.
Professional advice:"12 tons" is typically used to identify product level or maximum capacity and does not mean that the equipment can continuously lift 12 tons in all operating radii, boom conditions, and outrigger positions. Heavy-duty lifting should be based on the corresponding equipment load table, site survey results, lifting plan, and applicable safety regulations.
