Da Inglese a Italiano Tecnico/Meccanico Automobilistico/Auto e autocarri Autom. equipment

From a commercial letter:

"It was interesting to see the ramps in production and I was impressed by the machinery and the vast technology. I was also surprised to learn of all your different product ranges i.e. bench presses, gearbox jacks and oil drainers and I am sure we will be placing some orders in the near future."

What is "bench press" in automotive context? Trovo solo macchine per la palestra (le panche piane) ma ovviamente qui non ha niente a che fare...

Aiuto, è urgente! :)
