What happens here

An excavator equipped with a specialized grapple attachment is used to carefully lift and place large precast stair treads. Each tread is precisely lowered onto the prepared gravel base, and then fine-tuned for levelness by a worker. The presenter stresses extreme caution when working near heavy machinery, especially in 'pinch points' where body parts could be crushed, and advises against getting underneath suspended loads.

Goal: Precisely place heavy stair treads using machinery

[Music] all right so the next thing we're going to do is actually set one of the precast stone stairs so the front of the block he's got a pad in place he just wants to kiss it not crush it [Music] don't get under that block [Music] hey art you're in a pinch point you know art whatever you do don't get yourself trapped in pinch points where you can't get out if a piece of equipment does its own thing because we've seen equipment blow hoses crash down just be very careful about pinch points please and thank you [Music] so he's already got that all leveled okay [Music] we decided [Music] 99 of the work is in the preparation so although that looked pretty easy it wasn't easy to make sure that everything was set and ready so that he could make it look easy as he set the block in place
