A Melbourne tram operator Yarra Trams, and a contractor Downer EDI, required better access to the side and top and edge protection for the roof of the A, B and Z Class trams during the life extension program works, which included a full interior strip-out and replacement, servicing or replacing air-conditioning units on the roof work on the pantograph.

USAGE SCENARIOS

Here’s what SafeSmart’s custom shop designed and built, so workers could get the job done more safely and efficiently.

Side Roof Access Platform

• 6.4mL x 2.7mH x 1.0mW access platform.
• Platform base width 1.0m.
• Interchangeable LH and RH side guardrail frames allows the platform to be used on either side of the tram.

• Guardrail, midrail and toeboard frames to both sides of the platform with an access gate central on one side.
• Handrail and midrail on both sides of the stairway.
• Self-closing swing gate at both ends of the platform and casters set back allowing end-joining of two platforms.

Cross-Roof Guard Rail System

• Telescopic clip-on guardrails 2.5mL – 3.5mL

• Self-closing gates.
• Box section aluminium used in manufacture instead of C-channel or I-channel.
• Full design drawings completed for customer to sign-off before manufacture.
• Large 200mm swivel/lock castors as opposed to smaller castors which make it difficult to roll across tracks.
• Telescopic grasper rails allow use on multiple different tram types, saving money.
