Devices of the SR-250 type (standers) are intended for loading and unloading oil and oil products into sea and river tankers. Multi-row hinges provide ease of movement of the moving elements of the stander during long-term operation. Ideal balancing and low weight of the stander allow it to be operated manually by one person without additional mechanization. The outer cages of the hinges are interconnected by a bracket, which allows replacing the sealing collars without dismantling the stander and without disassembling the hinges. The grips can be rotated around the axis of the connecting head by 360 Β°, which allows them to be installed in any convenient place on the receiving flange of the tanker.
