Go-Go-Gadget Chinese Bomb Disposal

I was crossing the border into China the week before last week and spotted this rather interesting bomb disposal equipment, parked metres away from the queue in which I was standing. It seems somebody has to wheel up to the suspicious package or bag and using the go-go-gadget-like claw, pick up said object and place it inside the spherical caldron-like thingamajig (also on wheels). It must be quite scary and somehow comical at the same time. Apologies for the poor quality photo - I was trying to be discreet (note the yellow ‘No Photography’ sign on wall).
