JingShi manufactures free-standing and wall-mounted jib cranes for machine loading, assembly, maintenance, mold handling and localized material transfer. Standard systems are available in 125 kg, 250 kg and 500 kg capacities, with engineered configurations up to 5 tons. Working radius, lifting height, rotation range, rail type, hoist and control method can be customized for your workstation.




Six questions worth answering before a spec goes final — the ones we hear most often from procurement and plant engineering teams sizing a jib crane for a new or expanding cell.
Rated capacity should account for the load, the rigging, the gripper, and any offset tooling — not the part alone. Keep steady-state working weight at 70–80% of rated capacity to preserve smooth response and long-term reliability. Move up a size when picks are frequent, reach is long, or the load sits off-center.
Structural margin is governed by moment — load multiplied by horizontal distance — so the crane needs to be designed around the furthest, heaviest lift on the line, not the average one. Fixing column placement and rotation range early avoids interference with conveyors, machine doors, and safety fences later on.
Anchor design, slab thickness, and reinforcement layout all affect deflection and fatigue life over time. For multi-unit or multi-site orders, agreeing on one civil interface standard upfront keeps installation repeatable across every location.
| Mounting type | Best fit | Key verification items | Common pitfall |
|---|---|---|---|
| Floor-mounted column | General workshops, flexible layouts | Concrete strength, anchor pull-out, grout planarity | Underestimating slab reinforcement near joints |
| Wall-mounted jib | Tight floorspace, fixed stations | Wall/column structural capacity, bracket stiffness | Assuming masonry walls can take moment loads |
| Embedded foundation (new build) | High-repeatability, high-duty areas | Embed depth, rebar integration, alignment control | Misalignment that forces shimming later |
Operators tend to describe a crane as "light," "stable," or "twitchy" — useful feedback, but hard to act on until it's converted into start force, acceleration ramp, and micro-position stability. Once those are defined, the same handling experience can be replicated across shifts and sites. Separate speed profiles for transfer moves and final alignment usually solve this without retraining anyone.
Most handling complaints blamed on the crane actually trace back to the gripper. Use a spreader or dual-point grip when the center of gravity shifts between SKUs, add anti-rotation features for long or narrow loads, and define contact materials for finished surfaces to avoid cosmetic damage during handling.
Rated-load testing alone won't surface handling-feel or micro-positioning problems. For precision sheet metal, mold changeovers, or assembly support, these checks belong in the factory-acceptance plan:
| Test category | What to verify | Why it matters |
|---|---|---|
| Handling feel | Smooth start/stop, no oscillation, predictable response | Reduces operator fatigue and training time |
| Micro-positioning | Millimeter-level positioning under representative load | Prevents rework and tooling collision |
| Safety behavior | Overload response, limit actions, e-stop accessibility | Reduces incident probability |
| Structural stability | Deflection and settling behavior at typical reach and load | Protects precision processes |
