Retraction systems.No loop that keeps snagging.
A spring on the upper arm that pulls the protective hose back as the robot retracts, and releases it as it extends. That way there is never a loop in the cell and the hose wears less.

Retraction systems
- Operation
- Spring pulls excess hose back
- Place
- On the upper arm, behind the clamp on axis 3
- Hose sizes
- 17 to 70 mm
- Springs
- In different lengths per hose size
When a robot extends, the package needs more length than when it retracts. Without a retraction system that extra length hangs as a loop beside the arm, where it hits the cell, the workpiece or the robot itself.
The retraction system works like a ring the hose runs through. A protective ring on the hose engages the spring: when the robot extends, it pulls hose out of the safe zone behind the robot; when it returns, the spring pushes the hose back again.
Reiku supplies three versions of spring holders. We choose the version and the spring based on the hose size, the length of the arm and the movements of your robot.

Where it sits on the robot
A dress pack consists of hose, holders per axis and a retraction system. The highlighted part shows where this component sits; the other components link on.
- 1Protective hoseCorrugated hose for the cables and hoses to the tool. Absorbs abrasion, kinking and spatter.
- 2Rotary flange on axis 1Holder on a rotating flange, so the package rotates 360° with the base of the robot.
- 3Clamp on axis 3Clamp with clamping jaws that guide, hold or let the hose slide through on the upper arm.
- 4Retraction systemA spring that pulls excess hose back when the robot moves in, so no loop is left hanging.
- 5Ball jointLet the hose move along at an angle at the wrist, where axes 4 and 5 rotate.
- 6Mounting on axis 6End fixing at the tool. This is where the hose arrives at the welding torch, gripper or spray head.
Why
What makes retraction systems strong
- 01No hanging loop
- The hose stays close to the arm, in every position of the robot.
- 02Less wear
- No hitting the cell or workpiece, no kinking on entry.
- 03Safe zone
- Excess hose lies behind the robot, outside the working area.
- 04Fits in the system
- On the same clamps and hoses as the rest of the dress pack.
Application
Used in
- Welding robots with a long upper arm
- Handling with a long reach

How to choose
What to look out for when choosing
Not sure? Send us your details and we'll calculate it for you free of charge.
01Hose size
The version and spring follow the size of the protective hose.
02Movement of the arm
Lots of up and down movement? Then a tilting version or spherical shape.
03Difference in length
The spring length is determined by how much extra hose the robot needs.
04Space behind the robot
The retracted hose must be able to lie somewhere safe.
