Acquire mechanical design(s) options for a locking assembly to secure a 20" manlid for a tanker trailer.

LoadLock is a multi-component security system for liquid food and chemical road tankers. The system secures the commodity through a self proving electrical or pneumatic lock assembly at multiple charge and discharge points on the vessel. The mechanism will be powered with 12VDC and the mechanical action can be driven using either an electrical or pneumatic actuator. The working pneumatic pressure is roughly 100 psi. Each lock mechanism provides a contact closure signal that is monitored by an MCU controller. When all points are in a CLOSED state, the MCU arms the security system and the vessel is then considered to be sealed.
