WM8060 Column-Boom （Fixed and Revolve)
This welding center mainly consists of weld manipulators、SAW and electric system.
(1)This weld manipulators is mainly composed of：boom-elevate unit、boom travel unit、column revolve unit、movable trolley
、cross-slides、column、boom、trolley worktable and electric system；(if fixed type ,not provide trolley part)
(2) Both column and boom of weld manipulators are rectangular-section beams, with double-rail, which is welded into shape、stress-relieved and mechanical machined finely, ensuring higher precision；
(3)Boom-elevate unit is installed at column-top, composed of A.C. braking motor、reducer、chain and sprocket. It has counter-balance, making stable boom elevation. To prevent chains from incidental broken, ratchet-type anti-dripping unit on the column is used for safe and reliable operation.
(4) There are 8 sets of control rollers on the saddle along vertical and horizontal movement. Each set has 3 control rollers. These control rollers are contacted with rails of boom and column through 3-sides, of adjustable eccentric structure, with great loading capacity, making good contact between them and rail surface, ensuring smooth and no shivering boom travel；
(5) Boom travel is realized with A.C. inverter motor through worm-gear reducer
driving gear-rack. Its speed can be adjusted within 100-2000mm/min through inverter,
(6) Column is fit onto trolley through heavy-duty crossroll bearing. Column can be revolved within ±180° manual ; if no trolley part, column is fixed on one steel plate.
