3) main hook, secondary hook are hooked on respectively to firmly hook position, promoting main hook push and block plate with the movable coupler body lower end of main hook again clockwise rotates, under the resilient force of the hook lock pin back-moving spring of main hook, the movable coupler body lower end that the hook locking lateral pin termination of main hook puts in main hook links into an integrated entity the fixed hook of main hook and Removable hook; Another lower end depress switch control lever of main hook push and block plate, start stop lever lower end cross bar is depressed starting switch and is started wireless launcher and telltale; Then promoting secondary hook push and block plate with the movable coupler body lower end of secondary hook clockwise rotates, under the effect of the hook lock pin back-moving spring of linking up with in pair, the movable coupler body lower end that the hook locking lateral pin termination of secondary hook puts in secondary hook links into an integrated entity fixed hook and the Removable hook of pair hook; The telltale warning that pipes, shows all not yet locking of the hook locking lateral pin of main hook and the hook locking lateral pin of secondary hook;
4) press respectively main hook gauge tap and secondary hook gauge tap, the solenoid of hook lock pin control device obtains electric generation magnetic attraction lock pin body, lock pin body overcomes the elastic force of lock pin body back-moving spring, the cross-drilled hole that puts in hook locking lateral pin one end pins hook locking lateral pin, telltale stops piping, and shows that main hook and secondary hook are all in the lock state;
5) need to mobile main hook time, again press main hook gauge tap, the hook lock pin control device release of main hook, solenoid dead electricity magnetic force disappears, lock pin body departs from the cross-drilled hole of linking up with locking lateral pin one end under the resilient force of lock pin body back-moving spring, the hook locking lateral pin of the main hook that can extract; Start stop lever rises under start stop lever back-moving spring resilient force, and starting switch cuts out, and wireless launcher and wireless receiver are all in closed condition; While guaranteeing main hook release, the hook locking lateral pin of secondary hook is still in the lock state; Then the Removable hook of opening main hook takes off main hook;
6) while needing moving sets hook, again press secondary hook gauge tap, the hook lock pin control device release of secondary hook, solenoid dead electricity magnetic force disappears, lock pin body departs from the cross-drilled hole of linking up with locking lateral pin one end under the resilient force power of lock pin body back-moving spring, the hook locking lateral pin of the pair that can extract hook; The solenoid of main hook remains on to obtain electricity condition simultaneously, the hook locking lateral pin of lock pin body locking main hook;
7) repeating step 3)～4), the good main hook of hook or secondary hook again;
8) complete work high above the ground, need to take off main hook and secondary hook time, repeating step 5)～6) after, the power switch of pressing on main hook electric control gear is cut off the electricity supply, and telltale stops piping; Main hook and the release of secondary hook, extract respectively corresponding hook locking lateral pin, takes off main hook and secondary hook, and ribbon is taken in ribbon coiler simultaneously.
