Im not in construction..but in service you torque them up to however strong u are...and the strength of the spanner....

Motor horsepower requirements for elevators and lifts is determined by capacity, out of balance equipment weight, payload and operating speed. (i.e. - Total Lift Force X Speed) Other considerations include gearbox losses and overload requirements for acceleration.
