Recent Jobs
RPS was recently contracted to undertake an environmental impact study for a proposed wind farm. they hired us to install two microphones and a recording unit on two test towers including this 85m mast.
Cairns Rope Access have been working closely with High Access Communications providing Tower riggers and grounds crew. to assist them on mobile phone towers and masts up to 110m tall throughout central and far north Queensland. Our rope access background means we bring skills and techniques to the table which complement Hi Access's extensive industry knowledge and experience.
On a recent job our client needed to remove a 2.5m Microwave dish from the very top of this 110m mast and replace it with a 4.5m dish at 70m. The company's standard procedure is to run a winch through a puly slung off the steel work above then take up the strain un bolt the dish and lower it to the ground with a tag line. this mast presented a few problems firstly we would have needed more than 220m of winch rope and we would be exerting twice the weight of the load plus twice the already considerable wind loading on the very top of this mast well above the top guy wires. After discussing the pros and cons it was decided that we would lower the load from the top halving the force on the top of the mast and only needing 110m of rope the strain was taken up on a small come along then transferred onto the lowering rope on a porta wrap then lowered safely to the ground.
Cairns Rope Access have done another silo clean out for Cement Australia this time in there fly ash silos in Brisbane. in conjunction with transpacific industries we moved about 200t of old product.
Cairns Rope Access has just returned from Gladstone Where we have been performing visual inspections of the inside of Cement Australia's Clinker silos. The Clinker silos are a very hostile environment with poor visibility, low light, very high dust levels, extreme heat and difficult rescue scenarios.
Cairns rope access recently assisted Kelly's Aqua Jetting by pressure cleaning the inclined penstock as part of their major conduit cleaning contract at Koombooloomba hydro plant.
At 11:30 am on a Saturday in July,we received a phone call. Cement Australia Gladstone had called an emergency shutdown on Friday night to perform urgent repairs to one of the kilns. Welders where to enter the the base of the 70m high structure on Monday. The usual procedure is to install a number of protective decks from the top down but that takes about 4 days so they planed to just build the bottom one.
With about 60m of heat bricks and refractory over head there was no way the Riggers where going to be allowed to go in to build it.
Which is why they were calling us. They wanted to know if we could put a crew in Gladstone for Monday morning to perform an inspection and make safe work from the top down, before the Riggers went in. So we set to work and by Sunday night we had a crew in Gladstone with all their kit.
The work went well. We rounded off the trip by providing rescue cover for the riggers building the deck.
Laing O'Rourke has just finished building the new government offices in Cairns and needed to pressure clean the concrete slab edges. They looked at bringing in a large crane to suspend a man box to work out of. However putting a crane that close to the building so near hand over would have been risky, especially with the winds we get this time of year. So when we told them we could do the job quicker cheaper and safer they were interested.
They were still concerned about damaging the the top edge of the building which was made from apolic sheeting so we developed an edge protection system that spread the workers load over a meter.
As usual the wash down came off without a hitch and we were able to save them time and money.
