poor design definitely

 

Its an industry standard rod end, how old is that machine, you don't know that and you have no clue about its no doubt long history.

 

The fact that the end that has failed is, by design the bottom end of the ram means that when it failed the broken component stayed in place (failed safe). If it had been mounted the other way up the failure would have been very different indeed.

 

So good design and old age

Re: Safety Rope for MEWP

A dozen possible reasons for needing the fast rope technique.

 

1. A gang of yobs tie up your groundie and start to have some fun with the controls.

2. A gang of yobs start hooning their cars around where you are set up, lose control and crash into a leg

3. There is a mechanical failure which causes the machine to topple but leaves enough time to grab the rope

4. There is a failure of the ground under one of the legs, perhaps an old manhole with a rusty lid then covered with tarmac but not apparent when setting up.

5. An electric cable which was well clear of where you are working is brought down and over by a vehicle running into it and the cable falls across the MEWP making it live.

6. A drunk driver ignores all the barriers and crashes into a leg

7. A stolen car chased by the police rams a leg.

8. A light aircraft with engine failure chooses to land in your vicinity and crashes into a leg.

9. A deadly poisonous snake had found its way into the box section overnight and suddenly appears in your basket.

10. The acetylene gas bottle you were using to do some cutting suddenly has a blow back and safety valve failure and starts to heat up.

11. The can of paint thinner tips over and there is a spark and the whole cage starts to burn.

12. Monica Bellucci walks under the MEWP and says that she will give you a freebie if you slide down the rope.

14. You disturb a nest of asian hornets, and need a quick getaway!
