The Reineveldbrug is a movable bridge which is in proportion to other bridges rather broad for its cover.  As it happens she contains 4 lanes, 2 foot paths, 2 bicycle paths and 2 tram lines.

It is a modernisation project where a new bridge fall and new traction are placed.   Because of the lack of space in the existing cellar there has been opted for a split up, synchronised, mechanical traction.

The designconcept of the bridge fall and traction have been executed by a study office, designated by the construction lord. The task of Demako started with the detail design of the turn points and the movement work.

After approval of the implementation drawings the next phase has started, namely, the production. After fabricating and preserving all parts are as much as possible preassemblied in our works place, so that it could be placed in the cellar afterwards.

The drive mechanism exist of a centrally established electric engine with handbrake, which operates a square reduction case. The square reduction case operates 2 externally beared shafts which for their part intervenes on a central shaft with beared pannamawheeles.

The pannamawheel is not a complete wheel. .  It has been balanced with a leverage. These pannamawheels have been linked on the ballast side of the bridge fall by means of a spring buffer .

In case of electric panne the bridge can be handmoved with 2 speeds.

The bridge fall has been hinged established on 4 support points in line.  The 4 shafts twist in ballbearings with self-employed maintenance-free.  This whole movement mechanism is build on one frame and has a total mass of 180kN.
