Ladders & Stepladder assembly lines.

ME-A

Semi-automatic line which fixates pre-assembled ladders by riveting and expanding the ladder-steps into the frames.

• Pre-assembled ladders are placed by hand on insert-conveyor and automatically fed into the line.
• Automatic punching of holes in vertical profiles.
• Riveting and expanding is done automatically by double heads.
• Ladders are transported to output where they can be picked up by operator.

ME-PEA

Automatic line for punching and assembling pre-sized ladder-steps in pre-sized vertical profiles with extra automation steps.

• Pre-sized vertical profiles are placed by hand in insert of the line.
• Pre-cut profiles for ladder steps are placed by hand in magazine.
• Automatic punching of holes in vertical profiles.
• Automatic bar threading.
• Riveting and expanding is done automatically by double heads.
• (optional) Drilling in vertical profiles for attachments.
• Ladders are transported to output where they can be picked up by operator.

Stepladder machine

This assembly line is used for manufacturing aluminum stepladders. This line uses a high performance assembly technique by BOLLHOFF, normally used in the automotive industry. By using this technique, a very resistant assembly is made, with higher quality then the general pop rivet assembly.

The steps and vertical profiles are loaded manually by the operator on a special mobile tool. This tool is able to move in the caged part of the line.

4 BOLLHOFF crimping units move over the assembly by a carriage system, performing the automatic pop riveting of the stepladder.

Machine with mobile jig

This semi-automatic assembly line is made to automate the riveting and expanding of flared or conical aluminum ladders. The ladders are pre-assembled by an operator on a jig, this jig is specifically made for the parts to fit in their right positions. Afterwards the coinical ladder is automatically assembled by a two-headed riveting and expanding. By using a servo motor the jig gets driven.

Afterwards the assembled ladder can be taken off the jig at the output-side of the line.

This line is made to be handled by one operator.
