Manual Ergonomic Wheel-Lok

The Manual Ergonomic Wheel-Lok, or MEWL for short, is our new manual vehicle locking system. It provides reliable and effective protection against unintentional truck departures and trailer creep during loading and unloading operations at the loading point. Once the truck has docked at the loading point, the system is operated by the driver or the loading personnel on site.

The locking arm, mounted on a smooth-running slide, is positioned along the guide rail directly in front of the wheel to be secured. When the control lever is pressed, the arm moves forward and locks into place in front of the tire. Once engaged, the arm cannot be released from the outside—it can only be unlocked after receiving a signal from the control box inside the building.

Advantages of the MEWL:

Intuitive and simple to operate
Ergonomic and smooth-running
Robust system, solid construction, not very susceptible to damage
Temperature-resistant and weatherproof; due to the height of the product, the locking components have no contact with the ground. No sensitive electronic components.
Safe in case of water accumulation at the loading dock
Virtually maintenance-free, few moving parts
System meets FEM* Class 3 requirements for fully loaded semi-trailers
Full 24-month warranty; extension to 60 months possible – contact your Rite-Hite sales partner!
