Ideal for high-speed or high-cycle automated systems. GENERAL Principal components of the M Series are guide columns, carriage and a motor-gear reducer drive. STRUCTURE Guide columns are 6” wide flange sections. Carriage is fabricated with heavy structural steel members and a steel deck plate. Other deck surfaces can be supplied. Straddle or cantilever carriage available, depending on application. OPERATION Carriage is lifted and lowered by roller chain attached to an electric motor/reducer assembly mounted on the guide columns. Standard units employ 2 HP to 15 HP TEFC brake motors. ELECTRICAL Standard power requirements are 230/460VAC, 3-phase. Control voltage is 110VAC. Standard control panels and push button stations are NEMA 12 rated. Push button stations provided at each level include momentary contact, call/send operators and mushroom head emergency stop. SAFETY FEATURES Travel of the carriage is controlled by a limit switch. When the switch is tripped or power is lost, the motor shuts off and the mechanically actuated brake is engaged. Overload protection is provided by a relay that measures the motor current. If the current exceeds the amount required to move the maximum load, it will shut the unit down and engage the brake. Chain sensors shut down the lift if chain tension is lost. Chain tensioners and guides prevent chains from jumping on sprockets. NO RIDER signs posted at each point of operation. CARRIAGE SIDE GUARDS Carriage is equipped with safety rails on non-operating sides, and a safety chain, drop bars or gates on operating ends. Optional expanded metal or sheet metal carriage side guards available. SAFETY ENCLOSURES / GATES Safety codes (ASME B20.1) require interlocked gates with enclosures on all sides of the lift.

Carriage remains level regardless of load placement. GENERAL Principal components of the 21 Series are guide columns, carriage and hydraulic actuating mechanism. STRUCTURE Guide columns are 6” wide flange. Carriage is fabricated of heavy-duty structural members with steel deck plate. Other deck surfaces available. Straddle or cantilever carriage available, depending on application. OPERATION Carriage is lifted and lowered by two hydraulic cylinders mounted on guide columns. Cylinders are actuated by a remote mounted hydraulic pump. Transmission of the lifting force is through roller chain attached to the cylinders and carriage. A torsion bar links the two cylinders to equalize the load and ensure carriage remains level at all times. ELECTRICAL Standard power requirements are 208/230/460VAC, 3-phase (single-phase available). Control voltage is 24VAC. Push button stations and pump mounted pre- wired control panel are NEMA 12 rated. Push button stations provided at each level and include call/send operators and mushroom head emergency stop. Quick connect pre-wiring is optional. SAFETY FEATURES Upward travel of carriage limited by mechanical stops that ensure positive leveling with upper deck. Positive mechanical stops prevent overtravel. Pressure builds to “lock” carriage into position at upper level. NO RIDER signs posted at each point of operation. DeckLock Safety System available for added security at critical upper levels. CARRIAGE SIDE GUARDS Carriage is equipped with safety rails on non-operating sides, and a safety chain, drop bars or gates on operating ends.
