How is the parking brake on the MHU-110/M applied?

The parking brake on the MHU-110/M is engaged by pulling either one of the two hand levers located on each side of the front of the trailer. This mechanical method provides a straightforward and reliable way to secure the trailer in a stationary position. The use of hand levers is designed for ease of access and operation, allowing personnel to quickly apply the brake without needing to enter the trailer cab or manipulate complex controls.

The other options would typically imply different systems or methods of braking. For instance, pressing a foot pedal would suggest a system that is more common in vehicles with driver compartments, while a central knob or electronic switch would indicate more modern, automated braking systems not utilized in this particular trailer design. The MHU-110/M utilizes a pneumatic system and manual engagement to ensure the parking brake is firmly applied and easily released by personnel directly interacting with the trailer, emphasizing practicality and effectiveness in its operation.
