A free climber who successfully ascended a 1,280ft crane in Dubai was surprised to find it covered in grease, causing his hands and feet to slip.

In July last year, YouTuber Adam Lockwood, also known as Nuisance, shared a thrilling video of his crane climb. If you're feeling daring, you can view the footage here.

In the video titled "Hanging off the tallest crane in Dubai (390m) after getting caught," the free climber recounted how he was initially blocked from climbing the crane but managed to find an alternate route by chatting "some s**t".

Lockwood then goes on to explain: "I didn't want to walk up 77 floors in the 45 degree heat. I didn't think anyone would be in the elevator.

"He starts shouting at me in Arabic. I used Google Translate to explain how I was working on site and forgot something (obviously not true but it's always worth a try) so he sent me down the stairs, on my own.

"He showed me the stairs, watched me walk down a floor and left. I changed to the opposite stairwell and carried on going up, my blag worked."

As he climbed, he could hear workers occasionally on several floors and had to change stairwells multiple times during a two-hour period.

"When I reached the top I realised I had only brought one GoPro battery, and it was on 20 percent, meaning I could only film for a few minutes," Lockwood said.

The YouTuber then showed footage of himself climbing the structure and doing stunts, including hanging from one hand and suspending himself upside down with his legs looped over a bar.

He also displayed his dirty hands on the camera, initially believing the dirt was desert dust before realizing that the crane bars were covered in grease as the sun rose.

After safely returning to the ground, Lockwood stated that he had no intention of repeating the frightening ascent.

He ended the video with the words, spoken breathlessly: "Wow, I'm not doing that again. On my life, I'm not doing that again."

After performing the dangerous stunt, Lockwood cautioned, "Do not attempt this yourself," and went on to say: "When I first looked at the footage, I was thinking to myself, 'this is it, this is the most incredible thing I've done'.

"The fact I hung off the tallest crane in Dubai on the doorstep of the world's tallest building is something special and I feel like it was definitely worth the risk and legal consequences if I was caught.

"I put a hard hat on to blend in whilst walking past 100 workers and slipped out the back gate without being noticed.

"Climbing up the jib, I quickly realised the whole crane was covered in grease that I couldn't even see, at first I thought it was dust from the desert but checking my hands it was grease, feet and hands slipping on everything I touched.

"I had four close calls whilst climbing up and coming down I had a few close calls too."

Lockwood added: "Hanging off things doesn't feel like much, it feels surreal to be suspended that high with no safety, but like all my other hangs, my brain is blank, my heartbeat doesn't go up, and it feels almost peaceful.

"It's something I know I can do and that 99 per cent of the world can't and never will do, so I feel obliged to use my ability and enjoy doing it in the process.

"I love seeing things from height, I love having my body suspended hundreds of meters in the sky, I love the challenges of infiltrating secure places to achieve these goals and it's something that has kept me alive since I started, and I don't think I can give it up.

"I slept for the whole day when I got back to my accommodation because I was so tired."
