    • A liquid tank device (1) comprises a tank housing (2) for storing a liquid (11) within a tank volume (3) inside of the tank housing (2) and further comprises at least one conduit (4, 5, 15) for the liquid (11) that is connected in a liquid- tight manner to a corresponding opening (7, 8, 16, 17) within the tank housing (2) such that the liquid (11) can be supplied to or removed from the tank volume (3) within the tank housing (2) through the opening (7, 8, 16, 17). The liquid tank device (1) also comprises a containment housing (19), whereby the containment housing (19) is arranged on an outer side of the tank housing (2) in such a way that it surrounds at least one opening (8, 16) and an adjacent section (18) of the at least one conduit (4, 5, 15). The containment housing (19) can comprise an opening (23) for the conduit (4, 5, 15) or for a power line (12) that runs through the corresponding opening (8, 16, 13) of the tank housing (2) into the containment housing (19). The containment housing (15) confines in a liquid-tight manner a containment volume (17) for any liquid (11) leaking in the vicinity of the opening (7, 8, 13) of the tank housing (2).

    • A system (100) for dynamically testing a ground support element (102) for use in strata control in civil engineering and mining operations, the system including: a buffer (104); a frame (114) to be moved in a direction towards the buffer (104) from a first position, in which the frame (114) is spaced from the buffer (104), to a second position, in which the frame (114) is in contact with the buffer (104) so that movement of the frame (114) in the direction is at least slowed by the buffer (104), the frame (114) having an attachment portion (158) to be coupled to the element (102) so that the element (102) is movable with the frame (114); and a load mass (172) arranged for relative movement with respect to the frame (114) and operatively associated with the element (102) such that contact between the buffer (104) and the frame (114) causes the load mass (172) to move in the direction of movement relative to the frame (114) to load the element (102) thereby causing displacement of a portion of the element (102) in the direction of movement as the movement of the frame (114) is at least slowed, wherein the frame (114) has an end portion (148) to contact the buffer (104), with the load mass (172) spaced further from the buffer (104) in the direction of movement than the end portion (148), prior to contact between the end portion (148) and the buffer (104), such that the load mass (172) continues to move toward the buffer (104) in the direction of movement after the contact between the end portion (148) and the buffer (104).
