Series M Lift at Mezzanine

Mechanical Vertical Lifts - M Series Specifications


The M Series moves materials between two or more levels. Principal components are guide columns, carriage and a motor-gear reducer drive.


Lifts loads up to 10,000 lbs. Carriage sizes up to12’ x 10’ or more. Maximum vertical rise of 200’. Standard travel speed is 25-30 FPM (500 FPM or more available).


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.


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 10 HP TEFC brake motors. 


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 are provided at each level and include momentary contact, call/send operators and mushroom-head emergency stop.


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. Safety cams, mounted on the carriage prevent uncontrolled descent if chains break. Chain sensors shut down the lift if chain tension is lost. Chain tensioners and guides prevent chains from jumping on sprockets. NO RIDER signs are posted at each point of operation. Available with optional DeckLock Safety System.


Carriage is equipped with safety rails on non-operating sides and safety chains or diagonal drop bars on operating gates ends. Optional expanded metal or sheet metal carriage side guards available. 


Safety codes (ANSI/ASME B20.1) require interlocked gates and enclosures on all sides of the lift. Enclosures must be a minimum of 8' high and reject a ball 2" in diameter. PFlow manufactures gates and enclosures with 1/2" expanded metal in a structural angle frame.
