- A column-mounted manipulator transfers loads to its base. The foundation must resist vertical loads and overturning moments from rotation and eccentric loading.
- Foundation assessment covers bearing capacity, concrete condition, anchors, embedded components, level and working radius.
- Select foundation thickness, anchor specifications and fastening methods for the equipment load, working radius and installation drawings. Do not apply one fixed set of values to every installation.
- Do not install directly on an inadequate foundation; evaluate an embedded or reinforced foundation, or use an overhead-mounted or rail-mounted configuration.
A column-mounted pneumatic industrial manipulator connects to its foundation through a base. During lifting, rotation, extension/retraction and pick-and-place movements, loads from the machine, workpiece, gripper and motion transfer into the foundation. Foundation verification must cover the complete working range.
01Foundation loads and equipment stability
Inadequate foundation capacity or connections may cause a loose base, column movement, unstable rotation and positioning errors. With increased working radius, eccentric workpieces or long grippers, the base carries an overturning moment in addition to vertical load. Calculate these effects from the load and motion range; floor appearance alone is insufficient.
02Foundation assessment
Ground bearing capacity
Capacity checks must include the weight of the machine, workpiece and custom gripper, as well as dynamic and repeated loading. Verify foundation conditions for the specific model, load and working radius, and document them in the installation drawings.
Concrete condition
Inspect concrete for hollow areas, cracks, surface dusting, layers, loose material or settlement. A surface leveling layer is not automatically a reliable structural foundation. Where trenches, drainage channels, underfloor heating, embedded services or voids lie below, submit site information for qualified personnel to review installation conditions.
Expansion and chemical anchor requirements
Choose expansion anchors, chemical anchors or other anchoring methods for the foundation conditions. Verify drilling permission, reinforcement and service locations, embedment depth and continuity of the mounting surface. Address insufficient concrete strength or loose layers in the anchoring area before proceeding.
Foundations with embedded components
For higher loads, larger working radii, frequent use or demanding positioning stability, assess a foundation with embedded mounting components. Implement its dimensions, structure, reinforcement, embedded parts and construction requirements according to the installation drawings and complete it before equipment installation.
Mounting-surface level
An uneven mounting surface can affect column verticality, rotational resistance and arm loading. Recheck level before installation and perform leveling, shim-plate adjustment or foundation repair as specified. Do not use equipment adjustment to conceal foundation problems.
Radius and load variation
Foundation verification should cover different rotation angles, extension lengths and load orientations, especially maximum radius, eccentric pick-and-place tasks and flipping or rotation. The site assessment should also record the actual handling path, maximum extension position, operator positions and surrounding layout.
03Options when existing foundations are unsuitable
Do not install directly on an inadequate foundation. Assess an embedded or reinforced foundation, a different mounting position, an independent foundation, structural steel reinforcement, a wider base, a jib crane, an overhead manipulator or a rail-mounted system. Each option still requires calculations for rated load, working radius and the building structure, supported by corresponding installation drawings.
04Foundation checklist
| Item | Required checks | Risk | Recommended action |
|---|---|---|---|
| Bearing capacity | Confirm whether the installation area can withstand equipment, workpieces, fixtures and dynamic loads | Insufficient load-bearing may result in settlement, shaking or loosening of the base | Verify against equipment load, radius and installation drawings |
| Concrete floor | Inspect hollow areas, cracks, surface dusting, layers and loose material | Insufficient ground integrity affects anchoring reliability | Site engineering review; repair or relocate the mounting point where required |
| Expansion anchors | Confirm whether the ground is allowed to drill holes and whether the holes are located away from pipelines and structural weak areas. | Unreliable anchoring may cause long-term loosening | Install to the drawings and recheck fastening after installation |
| Chemical anchors | Verify foundation condition, hole cleaning and installation conditions | Incorrect installation reduces anchoring strength | Qualified personnel to follow the specified installation procedure |
| Embedded foundation components | Determine whether independent foundations or embedded parts need to be made in advance | Missing embedded components can delay installation | Complete and inspect before equipment installation, following the drawings |
| Level | Check the flatness and level of the installation surface | An uneven surface affects column verticality and slewing stability | Level before installation or adjust according to plan |
| Working radius | Confirm the maximum extension position and rotation range | Overturning moment increases under large radius conditions | Review based on rated load and actual handling actions |
| Load variation | Check workpiece weight range, tooling weight and eccentric loading | Load fluctuations may affect equipment stability | Provide information on the largest, smallest and most commonly used workpieces |
| Long-term stability | Assess frequent use, continuous operation and impact loading | Long-term repeated stress may cause foundation fatigue or looseness | Regularly check the condition of the base, bolts and columns |
| On-site review | Review foundation, space, interference and safety areas before installation | Incomplete on-site information may lead to rework | Complete joint site verification before installation and commissioning |
