Working platform, type GP-bpw

Application: Working platform, type GP-bpw, produced by BPW Ltd., is the basic element forming bigger platforms used during assembly of temporary and permanent linings in preparatory excavations headings (tunelled by means of heading machines and shot works), or in headings rebuilds.
GP-bpw working platform can be also used building foot-bridges where the floor is locally bumpy.
Characteristics: Certified steel profile with atni-slip surface is used for production of working platform, type PG-bpw.
As far as construction design is concerned, PG-bpw working platform fulfills requirements of polish norm PN-80/M49060 "Machines and Devices. Entries and accesses - Requirements" and BN-77/0414-12 "Pathways over main transport devices - design rules". It refers to design solutions applicable for loads not greater then 2.5kN per square meter of working area.
Technical data: Construction of GP-bpw working platform is compact and solid. Technical parameters of GP working paltforms allow to use them for building platforms, foot-bridges over transportation ways etc.
