Hammer Unions are precision machined to create the highest quality alloy steel and carbon steel finishes, resulting in precision sealing every time. The sizes available are 1 ~ 10″, 1000 ~15000 pressure capacities. Hammer unions allow pipeline couplings to quickly and easily effected or released and are effective under high-pressure conditions. Hammer unions are used in flow line rigging.
Hammerhead Tower Cranes is a fixed jib crane consisting of a steel-braced tower. The jib is extended backwards in order to form a support for the machinery and counter-balancing weight. In addition to the motions of lifting and revolving, there is a racking motion, by which the lifting trolley, with the load suspended, can be moved in and out along the jib without altering the level of the load. These cranes provide repair support for the battle fleet operating far.
