A vehicle is disclosed for providing increased friction between the wheels of a vehicle and the ground. An example vehicle includes an anti-lock brake system, inertial sensor, and wheels. The vehicle also includes a computing system configured to deploy aggregate to an area proximate the wheels, responsive to determining that a vehicle traction value is below a first threshold. The computing system is also configured to, after deploying the aggregate, deploy a friction mat to an area proximate the wheels, responsive to determining that the vehicle traction value remains below a second threshold.

There is provided a patient transport apparatus. The apparatus includes a height-adjustable assembly having a longitudinal axis. The apparatus includes a brake cable. The brake cable includes an elongate portion extending along the height-adjustable assembly and includes a slack portion. The apparatus includes a brake cable housing coupled to and axially offset from the height-adjustable assembly. The slack portion of the brake cable is enclosed within a hollow interior of the brake cable housing.

The present invention provides a method and apparatus for braking mecanum or omnidirectional wheels, by applying force to the rollers of a mecanum or omnidirectional wheel to prevent them from rolling when in contact with the ground or the floor. In some embodiments, it engages the rollers with teeth, rods, or wedges to generate friction and prevent them from rotating. The teeth, rods, or wedges rotate with the mecanum or omnidirectional wheel on the same axle, so the force can be applied and the rollers braked whether the wheel is rotating or not. In some embodiments, the force is applied using a servo or motor to push a thrust bearing, which then engages the rollers. In some embodiments, the servo or motor applies force using one or more gear racks, levers, cam wheels, or mechanical linkages.
