Lean manufacturing shop floor with pipe-and-joint flow racks and karakuri devices

Modular hardware for continuous improvement.

We design and build workstations, flow racks, trolleys and karakuri solutions using modular pipes and joints. Built for your process, easy to adapt and ready for the next improvement.

Why a Lean Tool Shop

Hardware that improves with your production.

Your production is constantly evolving. New products, improved processes and higher standards require equipment that can evolve with it.

We design and manufacture customized workstations, flow racks, trolleys and karakuri solutions using a modular Lean system. Every solution is engineered for your process and can be modified, expanded or rebuilt as your production changes.

Instead of replacing equipment every time you improve, you improve the equipment with your production. That means faster implementation, lower costs and a standardized approach that supports continuous improvement for years to come.

Product Categories

Everything you need to build the workplace.

Lean Pipes & Joint System

Lean Pipes & Joint System

The backbone of every flexible workplace

Coated steel pipes and modular metal joints that let you build, adjust and rebuild racks, trolleys and workstations without welding or specialist tools. The same components can be reconfigured as your process evolves.

Gravity Flow Rails

Gravity Flow Rails

Move parts by gravity, not by hand

Low-friction roller tracks and flow rails that turn any shelf into a smooth first-in-first-out lane. Perfect for line-side supply, kanban replenishment and empty-bin return loops.

FIFO Flow Racks

FIFO Flow Racks

Right part, right place, right sequence

Pre-engineered gravity flow racks that enforce FIFO for bins, boxes and kanban containers. Presents material at the operator, moves empties back to logistics, and keeps takt-time work standard.

Karakuri Solutions

Karakuri Solutions

Low-cost automation, powered by gravity

Mechanical karakuri devices that use weight, levers and counterbalances instead of motors or air. A quiet, energy-free way to lift, tilt, indexers and transfer parts along the line.

Ergonomic Workstations

Ergonomic Workstations

Built around the operator

Assembly and inspection workstations tailored to the task: adjustable heights, task lighting, tool shadow boards, ESD surfaces and cable management. Built from the same pipe-and-joint system so they keep evolving with the work.

Kitting Trolleys

Kitting Trolleys

Deliver material just in time

Modular trolleys, dollies and tugger-train wagons that move kits, kanban and finished goods around the factory. Configure the deck, drawers and handles for the load and route.

Individual

Customised solutions based on different pipe racking systems for industrial use.

Flexible

Easy adaptation and optimisation of existing lean solutions with the modular system.

Sustainable

Reusable and flexible components: "Screwing instead of welding".

How we work

From idea to impact.

01

Observe

We visit your production to understand your process and evaluate where customized hardware solutions can improve productivity, ergonomics and material flow.

On-site
02

Design

We design the complete solution-from concept and CAD to material selection, cost estimate and implementation plan. Everything is engineered to fit your production.

Engineering
03

Build

Once approved, we manufacture, assemble and install the solution. Every workstation, trolley and karakuri system is built specifically for your process and ready for immediate use.

Installation
04

Standardize

Once proven, the solution becomes your new standard. We document it, replicate it where applicable (Yokoten) and create a consistent way of working across your production.
