Ergomart's mobile triple monitor cart is a heavy-duty, sturdy unit that can support the substantial weight of three monitors while still providing easy movement of the entire device. Its large informational display area makes it ideal for many applications, including lobbies and storefronts, education environments and medical facilities such as operating rooms and other patient care environment monitoring.

Each of the monitors is attached via a VESA-compatible Tilter Head that provides individual tilt, swivel and rotation movement. The monitor attachments can be placed anywhere along the three-part articulating beam. If placed at the edges, the beam can accommodate three equally-sized monitors of 27" in width. The two outside monitors can be curved inwards for an arc-like formation, providing their size allows it. The maximum size is approximately 24" in width for the arc formation with equal sized monitors with bezel depths of 2".

At the base sits four heavy-duty casters which provide easy movement even when the largest monitors are attached. An easy-to-grip, flexible handle located under the monitors facilitates this movement. When the unit is stationary, two of the casters lock to keep the device stable and in place.  Cables and wires are kept close to the pole via cable clips attached at various locations.

The mobile monitor cart is also available in several other configurations - the dual mobile monitor cart and the compact triple mobile monitor cart with one monitor placed over two.


Our heavy-duty monitor carts can be augmented to support a large number of applications. This is because the SERIES-192 mounting pole available on all MCARTs is compatible with many modular devices.

  • Direct Mount components can be directly installed on the pole for mounting CPUs, monitors and other devices. 
  • The pole also accepts three types of mount kits, namely MKIT-E (single mount that installs anywhere along the pole), MKIT-J (a similar dual mount) and MKIT-Y (pole top mount). All three of these accept any SERIES-118 monitor arm or other device.
  • Accessories, such as monitor adjustment handles, barcode reader cradles and more can be added to these mounts.
  • Modularity also means that you can easily modify an existing cart at later time to accommodate your changing needs
  • If you need assistance with additional requirements, please do not hesitate to contact us. We have worked on many interesting solutions over the years and may already have a design that fits your needs.

MSpec drawing of MCART-03 rolling monitor cart shown from an isometric view.

The triple monitor cart comes standard with a 5-foot pole. The three monitors are attached to the three section articulating mounting beam and arranged side-by-side in a flat configuration.



Specification drawing showing the top view of the rolling monitor cart base.

This top view of the rolling monitor cart base illustrates the footprint of the base, which measures 23.7" x 25.0". The outside diameter of the pole fitting is 4.5" and the inside diameter is 1.9" - designed for the installation of a SERIES-192 pole mount.



Specification drawing showing the front and side views of the rolling monitor cart base, its height and clearance.

The monitor cart features four heavy duty casters, measuring 4" in diameter. The top surface of the base is 5.6" off the ground. The ground clearance is at 3.1", which is where the flange and the bottom of the pole are positioned. The total height of the cart is then found by adding 3.1" to the pole length. The flange that accepts the pole is offset towards the back of the 23.7" deep base.



Specification drawing showing the cross-section of the pole and a front view of the top portion of the pole, including the wire access opening.

The left image shows the crossection of the mounting pole with a 1.9" outer and 1.6" inner diameter. The right image shows a side view of the top of the pole, including the top wire access port, its location and size. A minor pole seam is visible through the opening.



MCART-03 specification showing the pole and base dimensions from a front view, including monitors in a flat configuration.

The total maximum width of the MCART-03 with the beams extended is 57". The central beam measures 30", whereas the left and right beams each provide 9.5" of effective length. The outer tilter heads can be positioned anywhere between 18.7" and 26.5" with respect to the center of the pole. The maximum height for mounting the triple beam while keeping the wire management opening accessible is 39" for a 4' pole, 51" for a 5' pole, and 63" for a 6' pole. All measurements are relative to the top surface of the base, which is itself 5.6" off the ground.



MCART-03 specification showing the monitor mounting dimensions from a top view, including monitors in a curved configuration.

The MCART-03 has outer beams that can be angled in for a curved viewing experience. The tilter mechanisms cam also swivel. In a flat configuration, each monitor’s maximum width can be approximately 27" wide. If the lateral beams are angled, the maximum allowable width for the monitors is slightly diminished. At a 24 degree beam angle, the maximum width can be around 24", assuming the monitors are 2" deep.

This large VESA bracket is intended for mounting a monitor or TV with a 200x200 mm, 100x200 mm, or 120x180 mm hole pattern. The central hole patterns are 50x50 mm, 75x75 mm, and 100x100 mm, enabling this bracket to attach to the mounting location (e.g. an Ergomart Tilter Head) using a VESA 75/100 adaptor.
