MACLEAN MC-790NG is a manual height-adjustable desk designed to provide a stable, ergonomic workspace without the need for electrical connection. The mechanism uses a hand-operated crank to raise and lower the work surface up to a maximum height of 120 cm and reliably supports loads up to 60 kg. The desk is intended for home offices, shared workspaces and other environments where a simple, durable solution for height adjustment is required.

Advantages

The robust construction offers a stable surface for monitors, laptops, keyboards and other peripherals, and the wide adjustment range enables ergonomic positioning for various users and tasks. Compact installation requirements and straightforward operation make the desk suitable for locations where silent, reliable height changes are preferred.

How to use

Position the desk on a level floor and ensure sufficient clearance around the work surface before operation. Use the hand crank to raise or lower the desktop to the desired height; rotate the crank smoothly and stop when the work surface reaches the preferred ergonomic position. Secure any cables and devices on the desktop to prevent interference with the adjustment mechanism. Regularly check fixings and fasteners and tighten if necessary.

Recommendations

To maintain optimal performance, avoid exceeding the specified maximum load of 60 kg and distribute weight evenly across the surface. Use the full adjustment range periodically to keep the mechanism working smoothly. For ergonomic setup, adjust the desk so the top of the screen is at eye level and forearms are parallel to the floor while typing.
