HYDRAULIC WINDSHIELD SYSTEM HWS 

5.

 

FEATURES 

5.1.

 

MAXIMUM PROTECTION SCREEN 

One of the HWS system’s limitations is the size of the protection screen that can be erected (mainly due to wind loads) 

The following limit value is meant to orient the user on the size of a protection screen including two masts: 

 

Pouring height: 4.5 m 

 

Screen width: 4.9 m 

The  maximum protection  screen  size  varies depending on the configuration of the HWS structure, and therefore each 

case requires a specific study. 

5.2.

 

PLATFORM CONFIGURATIONS 

Different platform configurations (elements and dimensions) depend on the live loads expected in each application. For 

that reason, an independent study should be performed for each different application. 

As general criteria, the maximum length of the platform will be limited by the protection screen width. 

Concerning the platform width, a study should be performed in each case. 

 

5.3.

 

HYDRAULIC SYSTEM LIMITATIONS 

Each 

Hydraulic Cylinder

 is capable of applying its maximum load on the 

Head HWS

 where it is positioned. The weight of 

the structure to be lifted must be considered to avoid any problems when lifting. 

 

Working load of the “Cylinder HWS”: 50kN
