It is mainly composed o€★↔f hoist structure, steel¶£ wire rope, rake buckδ ↓et, steel wire rope pulley, ra ke bucket elongation device, mechanica₹♦"l torque protection, motion drive, grou♦≥∑nd fixed track and m ♦obile drive positioning device. The pδ∏∏♠ositioning and cleaning ×≠function of the whole↕≥ machine, the lifting of the rake "'bucket, the opening and closin π¶g of the rake bucket dirt, and the≈↑ scraping of the rake b↔γ ucket dirt are the same as tha£ε<δt of the fixed installation of the ≈β÷steel wire rope traction rake bucket£$₹¶ grid decontamination machine, only th π≤εe shelf is separated from th§™e shelf, and the upper frame is ≈±all set on the moving dri€↔<Ωve. When decontamination ε♠is controlled with a stroke swi©α✘£tch, the rack can be mλσoved to the grille location where d≥₩<econtamination is required.
