Marco van Grinsven of van Grinsven Crane Hire and Transport BV approached Broshuis with a special request. If Broshuis was interested to develop and produce a platform trailer suitable for a 50 ton / meter rolling crane.

This trailer would have to be suitable to transport 3 metre high ‘portacabins’, and also long length loads up to 22 metres of steel, concrete and PVC etc. A trailer should be as functional as possible.

 

Knowledge and experience versus development and innovation

In the past Broshuis has manufactured various extendible platform trailers with a floor height of 1.150mm. However in combination with a 50 t/m rolling crane, with different stresses on the cross members and the central main beam was completely new. Naturally we gladly accepted the order and it would be a challenge for our engineering department. First of all smaller tyres (235/75 R17.5” in stead of 275/70 R22.5”) are fitted to improve the platform height.

Then we used different types of steel with a greater tensile strength in combination with special constructed (low) cross members. Normally one would use high cross members and central main beam to create sufficient rigidity in the chassis, but this was not an option due to the required platform height of 1.150mm.  

The platform height of 1.150mm is essential due to obtaining a dispensation in Holland unto a height of 4.15m (3 + 1.15m).

 

 

 

Cooperation

The trailer was delivered in June 2007 to Kluitmans in Budel (NL) for the fitting of a Kennis crane and ‘operational test’. The trailer was tested to 125% over load and passed with flying colours. This was also noted by Marco Van Grinsven, who was very pleased by the cooperation with his company, Kluitmans and Broshuis.

The experience that Broshuis has achieved with the design, manufacture and testing of this extendible platform trailer with a heavy crane profile has led to various follow on orders.

 

Once again a customer wish is completed to full satisfaction.
