This disclosure describes a dock leveller lip control system designed to maintain continuous contact between the leveller lip and a trailer bed during loading or unloading operations. The system addresses the problem of trailer suspension settling, which causes the trailer bed height to decrease as its load increases, potentially leading to a loss of bearing for the leveller lip. It incorporates mechanisms for detecting lip contact loss and features an interlock with a vehicle restraint system to ensure operational safety and efficiency. The control system permits a designated settling range while actively managing lip position to ensure proper load transfer.

This disclosure describes an arrangement for suppressing dust at bulk material transfer points. It employs a staged enclosure around the material drop zone, paired with an induced air balance system. The enclosure design promotes staged particle settling while skirt seals minimize uncontrolled air ingress. An air extraction system maintains a net inward airflow, preventing dust escape. The induced air volume is determined by material flow characteristics and drop height, ensuring efficient capture of airborne particles. Adaptations for sticky materials are also detailed, addressing potential accumulation and flow issues within the system.
