How to Select Remote Control, Moment Limiter, Hydraulic Fly Jib and Basket Options for a 12-Ton Spider Crane
A 12-ton crawler spider crane may operate in confined lifting zones, uneven terrain and elevated work areas where the lifting plan requires more than standard crane configuration. For the Onchtech 12-ton spider crane, remote control, moment display, hydraulic fly jib and personnel basket options should be selected according to the intended task, site access, load path, ground conditions and applicable safety requirements.
These options are project-dependent. They should be reviewed together with the approved lifting plan, local regulations and the equipment documentation for the final machine configuration.
Start with the lifting task, not the option list
Option selection begins with a clear definition of the work requirement. A crane used for structural installation inside an industrial plant may need a different configuration from a crane used for rooftop lifting, substation construction or bridge maintenance. The same option can support different workflows, but its suitability depends on the actual operating conditions.
What each option is designed to support
| Option | When it may be considered | Selection considerations |
|---|---|---|
| Wireless remote control | Restricted lifting zones or tasks where an appropriate operating distance can improve the operator’s view of the load and surrounding area. | Confirm communication procedures, visibility, designated operating position and site safety controls. |
| Moment display | Lifting operations where operators need clearer reference information for monitoring lifting conditions. | Use the display in accordance with the machine instructions and lifting plan; it does not replace competent planning, inspection or operational judgment. |
| Hydraulic fly jib | Tasks requiring additional reach or greater flexibility in positioning a load around structures or obstructions. | Evaluate the required working geometry, clearance, load chart applicability and the effect on the planned lift. |
| Personnel basket | Applicable elevated-work requirements where a personnel-lifting arrangement is permitted and specifically planned. | Confirm local legal requirements, approved procedures, compatible equipment documentation and all applicable personnel-lifting safety measures. |
Remote control for restricted lifting zones
A wireless remote control can be considered when the operator needs to work from an appropriate position away from the crane, such as in narrow spaces, around structural obstructions or where direct observation of the load is important. It can support a more flexible operating position while the team maintains safe communication and site control.
Planning point: Remote operation should be incorporated into the site communication plan. The operator must remain in a suitable position with awareness of the load movement, exclusion zones and nearby personnel.
Moment display for lifting-condition awareness
A moment display provides information that can help operators monitor lifting conditions during planned work. It is particularly relevant where working radius, load positioning or changing operating geometry requires careful attention throughout the lift.
Planning point: A moment display is an operational reference tool. Final decisions must continue to follow the applicable load chart, equipment instructions, lifting plan and site safety procedures.
When added reach or elevated work is part of the project
Hydraulic fly jib
A hydraulic fly jib may be relevant where the main boom configuration does not provide the required positioning flexibility for the planned task. Before specifying this option, the project team should assess the target lifting point, required reach, clearance around structures and the machine configuration approved for the work.
Personnel basket
A personnel basket is not a general-purpose lifting accessory. It may be considered only for applicable elevated work requirements, subject to project approval, relevant regulations and equipment compatibility. The intended work method, rescue planning, operator procedures and required safety measures should be established before a basket configuration is confirmed.
Configuration review for the Onchtech 12-ton crawler spider crane
The Onchtech 12-ton crawler spider crane has a compact 1.86 m overall width, a crawler undercarriage and a combined outrigger arrangement designed for complex jobsite conditions. Its stated machine data include up to 21 m ground lifting height, up to 19 m working radius and an outrigger extension of up to 7,600 mm. These characteristics provide useful context for access and setup planning, but do not by themselves determine whether an option is appropriate for a specific lift.
- Define the work: identify the load, required lift point, lifting radius, elevation and movement path.
- Assess the site: check access, ground bearing conditions, slope, outrigger setup area, overhead clearance and surrounding hazards.
- Match the option: select remote control, moment display, fly jib or basket only where it supports the approved work method.
- Verify documentation: confirm the final configuration against the relevant product documents, load charts, safety requirements and project-specific instructions.
- Prepare the operation: establish inspection, communication, exclusion-zone and emergency arrangements before work begins.
Configuration principle: Choose options to suit the lifting plan and work environment—not simply to add functions. Final equipment selection should be confirmed for the specific project, site conditions and applicable safety obligations.
As the equipment brand of Hunan Hongchang Machinery Co., Ltd., Onchtech supports B2B equipment and configuration discussions for project-specific requirements. For a 12-ton spider crane option review, provide the intended lifting task, worksite information and relevant project requirements so that the proposed configuration can be assessed against the applicable equipment documentation.
