MRI Suites
Direct Answer: Can you use traditional industrial machine skates to move equipment into an MRI suite?
Traditional steel rigger skates and dollies cannot enter active MRI suites because the intense, continuous magnetic field transforms ferromagnetic tools into dangerous airborne projectiles. Nonmetallic Machinery Sliders™ provide a safe alternative; constructed from 100% solid engineered polymer with no metal wheels, bearings, or hidden pins
, they offer an ultra low profile (3/8″ to 1″ ride height) that safely spreads multi-ton equipment weights without point-loading sensitive, shielded medical floors.
The Magnet Is Always On
The Danger of Projectile Hazards:
A superconducting MRI magnet typically remains fully energized around the clock, regardless of patient schedules or room lighting. Any ferromagnetic object brought into the magnet room is pulled toward the scanner bore with immense, life-threatening force. This includes standard steel skates, hydraulic toe jacks, rigging chains, hand tools, and even small hidden fasteners inside seemingly nonmetallic enclosures.
To manage this extreme risk, medical imaging centers enforce a strict four-zone access framework. Zone IV—the magnet room itself—remains under the tightest surveillance, and every equipment move must be pre-approved by the healthcare network’s MR safety leadership. For reference, standard hospital compliance details can be found under the University of California, San Francisco (UCSF) MRI safety guidelines.
Why Ramping Down Is Not an Option:
Conventional heavy equipment skates and dollies are constructed from steel frames, iron axles, and metal ball bearings. Near an active magnet, these components are an immediate catastrophe waiting to happen. Healthcare facilities will not shut down or “quench” a superconducting magnet for a routine equipment replacement or service call. Ramping down a scanner is a major, logistically complex, and exceptionally costly procedure that releases cryogens—never a viable shortcut for a rigging crew.
Why Machinery Sliders™ Fit MR-Controlled Environments
100% Solid Polymer Engineering:
Machinery Sliders™ are molded as solid, high-tensile engineered polymer blocks. There are no metal inserts, no internal structural pins, no hidden hardware, and no greasy roller bearings. This pure nonmagnetic and nonmetallic composition provides the ideal starting baseline that MR safety officers require when evaluating tools for the facility’s outer security zones.
Low Profile Configurations for Shielded Openings:
Medical imaging suites are built as strict radiofrequency (RF) shielded enclosures. The specialized doors, waveguide openings, and access pathways feature exceptionally tight physical tolerances.
- Single-Direction Sliders: Raise the machine just 3/8″ (9.5mm) off the floor surface.
- Multi-Directional Sliders: Add 1″ (25mm) of overall height, which drops to effectively 1/2″ on the 4″-opening model where equipment leveling feet rest recessed inside the slider block.
This ultra-low clearance profile ensures tall medical or mechanical components pass under tight doorway thresholds without striking structural frames.
Crucial Non-Point Loading Floor Protection:
The floors inside healthcare facilities and MRI suites contain embedded copper or steel RF shielding mesh and sit over delicate structural frameworks. Concentrated wheel point-loads from standard machine moving skates compress flooring materials, causing expensive, disruptive damage. Sliders distribute weight evenly across their entire flat bottom face. This non-point loading architecture protects high-end sheet vinyl, linoleum, and transition thresholds along the entire delivery route.

The Approval Chain Governs the Move
Screening Every Single Component:
Within MR-controlled areas, the host facility’s designated MR Safety Officer (MRSO) must physically inspect, test, and approve every piece of rigging equipment before it crosses the safety threshold. This includes the machinery itself, the sliders, the non-ferrous pulling rigs, hand tools, and personnel.
Important Safety Note on Accessories: The structural retaining pins and alignment bolts sometimes utilized with our 1″-hole multi-directional sliders are user-supplied and typically made of standard steel. These accessory items must remain completely outside the Zone IV magnet room unless they have been explicitly screened, verified, and tagged as safe by the facility’s MRSO.
The Honest Fine Print:
No responsible industrial vendor can or should market rigging hardware as universally “MRI Safe” out of the box. Official MR-environment classification is legally the sole responsibility of the facility’s medical physics team, who must evaluate the complete product layout for their specific scanner site and static magnetic field strength (e.g., 1.5T or 3.0T). What we guarantee is the physical makeup of our hardware: solid polymer blocks containing zero metal, zero hidden fasteners, zero roller assemblies, and zero greasy bearings.
The Practical On-Site Workflow:
By switching to nonmetallic sliders, rigging teams keep large steel components completely out of the high-risk zones. The heavy machine rides low and highly stable over the hospital floor. The forklift, tow vehicle, and steel-wheeled low profile skates dollies remain safely outside the controlled zone perimeter. Final placement inside the magnet room is executed smoothly using manual push force or nonmagnetic winches, backed by 360-degree multi-directional sliding control.
MRI Suite Moving Questions, Answered
Yes. Superconducting MRI magnets remain continuously energized even when the facility is closed or patients are not present. Assume the static magnetic field is live at all times. Demagnetizing or quenching a scanner is an expensive emergency procedure, never a routine step for an equipment installation.
The sliders are molded into a solid engineered polymer and contain absolutely no metal components, steel axles, or bearings. However, formal site-specific clearance remains the legal responsibility of the facility’s MR Safety Officer, who must inspect and screen every piece of equipment prior to room entry.
RF-shielded access doors, waveguide entries, and specialized corridors have very tight overhead vertical clear spaces. At just 3/8″ to 1″ of added ride height, sliders maximize available space that 4″ to 6″ wheeled industrial skates would completely consume, preventing building structural impacts.
The hospital network’s MR safety leadership team holds absolute control. They screen all equipment, define the supervised travel path through the security zones, and verify the safety plan. Rigging crews operate strictly inside these parameters to ensure medical facility compliance.
