Case Study
One person, on the ground, changing a light five stories up
A Japanese facility maintenance tool brand asked us to make a light bulb changer pole. Japan expects a high standard of quality and safety, and this pole is built to it. The product design and the market are the client's; we handle structure, tubing, locking, inspection and shipping.

01 What the pole has to solve
Changing high bulbs used to require a lift. This pole lets one person do it from the ground: it reaches high enough, the head lines up with the bulb, and the lock holds firm while the pole turns. Faster, and lower cost.
02 What makes it hard
The higher, the harder to control
The longer the pole, the harder it is to line the head up with the bulb.
Easy to hold at full length
The total weight has to stay low enough for one person to control.
The lock must hold while turning
Changing a bulb means turning the pole, so the lock has to stay engaged and never collapse onto the user.
Long service life
The locking structure must not turn brittle over years of use.
03 How we built it, step by step
A 52 mm base section
The base section is 52 mm aluminum, with each section stepping down so the pole gets lighter toward the top.
Fluted reinforcement
The base section uses externally fluted aluminum for strength and stability.
External twist lock
Locks firmly, holding still while the pole turns the bulb.
Quick-change coupler
Delivered semi-finished: the pole plus a quick-change coupler for the client's own bulb head.
Length by ceiling height
Length and section count follow the building height, up to five stories.
04 How it is used
Three steps: attach the bulb head, extend and lock with the external twist lock, then turn the pole to remove or fit the bulb.
05 How it is tested
•Destructive test of the locking structure: confirms it will not turn brittle with long use
•Pull test: the force it withstands along the shaft when locked
•Axial load test: the weight it carries along the shaft when locked
•Telescoping cycle test: about 7 cycles per minute, extending and collapsing repeatedly

07 These capabilities can work for your product too
Destructive testing
Locking structures are destructively tested to confirm they will not turn brittle.
Sized by height
Set the working height first, then work back to section count and length.
