Hydraulic pressure loading trolley:

1. Function:Working as prepare, transit and hang materials. Lifting and horizontal movement,which is very convenient to lead the steel coiler to collapsible drum coiler, using hydraulic cylinder to lift,using cycloid reducer to horizontal movement
2. structure:welded by steel plate and profile steel
3. Max weight load:30T
4. Walking motor:BWED41-121-2.2KW(Changzhou )

Singer - cantilever type of Hydraulic pressure uncoiled:

1. function:Singer – cantilever rectangular pyramid has expansion and contraction ways materials hanging conformation,magnetic powder clutch(mode: FZJ-500) controls constant tension open-book:it is with emergency brake,feeding materials steady as the speed of main cutting machine.
2. structure:Made by uncoil rack and roll drum. uncoil rack is welded by steel plate and profile steelRoll drum made by center axis and sector board.
3. Max weight load:30T
4. adaptive swelling coil inner hole:φ508mm  φ610mm(need to add diameter-increase pad)

material hanging support:

1, The main function is reducing load for main bearing,make main bearing uniform load,in case of main bearing's deform.

2, made by rack,oil cylinder,support,swing arm,shaft pin and so on,automatic hydraulic pressure driving feeding machine, leading terminal and shoveling terminal:

• function:through automatically feeding materials and working by hydraulic shoveling terminal,move leading terminal safely, then send in Traction pinch initial correction machine.
• power:BWED42-187-2.2KW(Changzhou) GERMANY LISNO
• structure:Welding by steel plate and profile steel.

Traction pinch initial correction machine:

1, function:For uncoiling steel coil and sending to next step. Control hydraulic cylinder and synchronous up/down device to adjust pinch roll and uncoil roll.

2, motive power:22KW DC adjustable speed motor
