A jack including a first fluid actuator (228) having a first barrel (260) and a first piston (270) slidably received in the first barrel (260). The first piston extends relative to the first barrel in a first direction. The jack further includes at least one second fluid actuator (232) coupled to the first fluid actuator. Each second fluid actuator has a second barrel and a second piston slidably received in the second barrel. The second piston extends from the second barrel in a second direction opposite the first direction. |
