ABSTRACT:
A modular chemical handling apparatus has a first component coupled to a second component. The first component is retained proximate to the second component by a locking mechanism. Fluid conduit connection devices and/or electrical connection devices in the first component are coupled to corresponding conduit connection devices and/or electrical connection devices in the second component by couplers. At least one laterally sliding lock shaft is employed for coupling the first module to the second module and for decoupling the first module from the second module. In one embodiment, counterweights are used to maintain the sliding lock shaft and each of the connection devices in the fully coupled position.
