The present disclosure discloses an automatic leveling control method for a four-leg support working platform, which comprises the steps: determining the mass center position of the working platform, determining the main bearing quadrant and distinguishing active legs from the driven leg; adjusting the driven leg to weak state, controlling all legs to synchronously actuate for leveling; calculating the limit compensating actuation length of the driven leg, and performing compensating actuation until accomplishing the leveling process. The method is advantageous in: high speed, high robustness, no repeated oscillation. The mass center always stays within the bearing zone of the active legs, thus completely eliminating capsizing risk of the working platform. The compensating actuation of the driven leg ensures there is no weak leg, and hence high attitude and load-bearing stability of the working platform is achieved.

A landing pad that mounts to a foot of a vehicle support. The landing pad includes a bottom with an opening. A side wall extends upward from the bottom with the side wall positioned around a perimeter of the bottom. A top shelf extends radially inward towards the opening from the side wall with the top shelf extending over and being spaced away from the bottom. One or more slots extend from the top shelf to the opening. Each of the one or more slots includes a first section that extends into a lower surface of the top shelf and a second section that extends into a top surface of the bottom with the first section and the second section of each of the one or more slots being aligned to direct water to the opening.

A system and method for remotely controlling loading dock components is disclosed that includes a distribution center having at least one dock station for exchanging materials and a dock component configured to in at least two operational states. An actuator is included that is configured to change the operational state of the dock component in response to an activation signal. A mobile remote control is configured to generate the activation signal to cause the actuator to change the operational state of the dock component and at least one predefined non-activation zone is included such that changing of operational state of the dock component is inhibited when the mobile remote control is located within the at least one predefined non-activation zone.
