Main Components

Steel coil loading table:

This table is used to store steel coil and it is convenient to load steel coil on coil car. Buyer needs to find a suitable area for this loading table. The table outer form is “V” style, max loading capacity is 15000kg.

Suitable steel coil outer diameter: 800~1800mm. Suitable steel coil width: 400~1220mm

Coil car:

Coil car is used to load steel coil and make steel coil load on decoiler shaft.

Max loading capacity: 15 tons. Lift height: 750mm. Horizontal moving speed: 6m/min. Lift power hydraulic cylinder diameter: ¢180×75mm. Move speed: 6m/min

Hydraulic power drives hydraulic cylinder to push coil car support table, and make it lift up and down. The support table is “V” style, the surface is covered nylon plate. Main aim is to protect the steel coil surface quantity. Motor and decelerator drives coil car move on rail, it is convenient to load steel coil on decoiler shaft. Coil car support table surface matches with rubber plate, in order to keep steel coil fixing well on it.


The decoiler is automatic model, motor power drives decoiler shaft open steel coil and hydraulic power expands steel coil inner surface, in order to make steel coil fix well on decoiler shaft. Decoiler is single head model, it has assistant support device, it will protect decoiler shaft to load well steel coil on working condition.

Max capacity of decoiler 15 tons
Decoiler shaft expanding range 50mm
Suitable steel coil width 1220mm
Suitable steel coil outer diameter 800~1800mm
Main motor power 11kw

Decoiler also includes one press arm, when decoiler is on working condition, press arm will push down and press well steel coil surface, it will protect operator and do make operator to be hurt by steel coil.
