Open the catalog to page 4UNI-LIFT Solutions in Action ® Engineers utilized two (2) UNI-LIFT® 100-ton Actuators with 15' of travel to raise and lower the ramp on each ferry dock along the Mississippi River, USA. The Department of Transportation engineers needed a way of lifting and lowering ramps during high and low tide conditions, while holding up to the harsh environmental conditions of the Gulf Coast. When engineers needed a quick and compact way of opening the large doors of these plating tanks, they selected a UNI-LIFT® solution. The application utilizes two 5-ton double-clevis Actuators, with a motor and a...

Open the catalog to page 7UNI-LIFT System Design ® Key Points to Consider When Properly Sizing an Actuator • Total system load • Application loading conditions • perating intervals of O the actuator • Linear velocity requirements • Ambient temperature • Environmental conditions • Mounting position requirements • Load screw configuration • Screw length requirements • End mounting requirements • System components needed Refer to technical specifications on pages 14 & 36. Total Load Requirements UNI-LIFT® Actuators can be used individually or in combination with each other to move a load. • When a single actuator is...
Open the catalog to page 8System Design Usage Requirements • Operating Cycle Requirements determine the type and size To of the actuator, calculate the required duty and operating cycles. Refer to the Yellow Pages 70 & 75 for Duty Cycle information to properly size your actuator. • Linear Velocity Requirements Linear velocity is the speed that the actuator moves the load based on the output speed of the motor. Turns Per Inch (TPI) is the number of rotations of the actuator's input shaft required for one-inch of travel. Actuators are available in two to three different gear ratios. • Environmental Conditions The...
Open the catalog to page 9UNI-LIFT System Design ® End Configurations • Threaded End (1) The end of the load screw is machined to include a standard unified V-thread form strong enough to sustain the load capacity of the actuator. This option can be used to attach customer supplied mounting configurations. • Plain End (2) The end of the load screw is machined to provide a smooth, unthreaded portion suitable for engaging pillow blocks or other bearing supports. Bearing supports are highly recommended when long load screws are used. This option is only available with the Rotating design. • Clevis End (3) The end of...
Open the catalog to page 10System Design Determine The Extended Screw Length (ESL) The length of screw that is needed to achieve the required movement, and allow for boot closed heights, traveling nuts, stop nuts and the thickness of the supporting structure between the actuator and the load. Mounting Structure Refer to the Yellow Pages 71 & 76 for more information on ESL. Travel System Arrangement Actuators can be configured in multiple system arrangements to allow synchronized lifting. Even when the loads are unequally distributed, the system can lift uniformly. Enerpac offers a complete line of power transmission...
