HMA - Hydraulic Manipulator Arm

The HMA is Ergonomic Partners' heavy-duty hydraulic manipulator arm, designed for precise handling of large, awkward loads. Its parallel arm articulates at three rotation points using precision bearings, allowing smooth, controlled movement throughout the work area. Operators position the load horizontally by moving the arm, while a hydraulic cylinder provides proportional vertical movement. Low-voltage variable-speed controls can be handheld, machine-mounted, or integrated into a dedicated control station.

ABA - Air Balancer Arm

The Air Balancer Arm (ABA) shown here was designed for handling boxes weighing up to 75 lbs. in a low-headroom application. Its extended handle includes two sets of controls, allowing the operator to control the arm when placing boxes at upper or lower levels. An interlocking control is intended to prevent the load from being released accidentally while suspended. This application-specific arm is less than 10 ft. tall and can place boxes at heights up to 73 in.

SJM - Super Jib Manipulator

The Super Jib Manipulator (SJM) is a lightweight jib designed to provide extended vertical travel and reach for industrial handling applications. Depending on the application, vertical movement can be provided by an air balancer, VFD-controlled hoist, air hoist, or intelligent zero-gravity hoist. Its reach makes the SJM suitable for machine-access applications and paint-line loading and unloading. An optional high-speed hoist is also available for applications requiring faster vertical movement.

EMA - Easy Manipulator Arm

The Easy Manipulator Arm (EMA) is a pneumatic manipulator designed to provide smooth load movement with proportional operator control. Its lift cylinder uses compressed air for vertical movement, while a standard operator-controlled up/down metering valve supports precise positioning.

Multiple handle styles are available, including an extended handle for applications requiring a different operator position or reach. Precision bearings at each articulation point help minimize resistance during horizontal movement. The EMA can also be configured for drum-handling applications that require lifting, rotating, and pouring.

SVL/VLC - Straight Vertical Lift Cylinder

The standard SVL/VLC models shown below offer lifting capacities up to 850 lbs. for straight-line transfer, over-the-assembly-line handling, and reach-in operations when combined with an overhead rail system.

The SVL/VLC can be configured with a pneumatic lift cylinder or an electric chain hoist. The system provides smooth, controlled vertical movement and can accommodate off-center loading. Control circuits and auxiliary components mount on the cylinder case, helping keep the tooling area and operator sight lines clear. The vertical lifter can be mounted on a dual monorail or double-girder overhead crane. Ergonomic Partners fabricates manual push-pull crane systems as well as electrically powered systems with variable-frequency drives.

RIA - Reach-In-Arm

The Reach-In-Arm (RIA) combines design elements of the EMA and LMA in a pneumatic manipulator developed for applications requiring extended reach under restricted overhead clearances. Its low-headroom configuration makes it suitable for CNC machine loading and other applications where the arm must reach beneath or into equipment.

The RIA can rotate up to 360 degrees and allows the operator to work from the side of the machine while positioning the load. This arrangement extends the operator's reach without requiring them to stand directly in front of the equipment.
