A separation apparatus that includes a weir tank having a plurality of cells and fluid removal apparatus for each cell to remove the fluid from each cell. The fluid removal apparatus includes an actuator and an extension arm whose movement is caused by the actuator. In addition to the actuator and the extension arm, the fluid removal apparatus includes a plunger attached to the extension arm for selectively engaging a first opening in each cell. Furthermore, a method of removing fluid from the separation apparatus via the fluid removal apparatus.

A loading arm includes a stand pipe, a coupler configured to be connected to a tank to deliver a product, and a pipe assembly having a first pipe end pivotally coupled to the stand pipe and a second pipe end pivotally connected to the coupler. The pipe assembly includes a pivot joint disposed between the first pipe end and the second pipe end such that the pipe assembly is movable between a retracted position and an extended position. A linkage assembly has a first portion connected to the pivot joint and a second portion connected to the stand pipe. The linkage assembly is operable to allow for the positioning of the coupler at any of a plurality of points corresponding to the pipe assembly being positioned between the retracted position and the extended position. The linkage assembly is fully supported by the stand pipe such that movement of the pipe assembly does not require manipulating the weight of the linkage assembly.

A device for pulling a hose and nozzle assembly comprises a laterally-extending grip manually engageable by one or both hands to grip the device and pull a hose and nozzle assembly attached thereto. A lock is spaced below the grip and is releasably engageable with the hose and nozzle assembly. The lock or hose and nozzle assembly is movable relative to the other between (i) a locked position, wherein the hose and nozzle assembly is secured by the lock to the device and the hose and nozzle assembly is supported therefrom, and (ii) an unlocked position, wherein the hose and nozzle assembly is released from the lock and detached from the device. In the locked position, the laterally-extending grip is manually engageable to pull the device, including in a position behind the back, and thereby pull the hose and nozzle assembly secured thereto.
