Mechanical Vertical Lifts - F Series Specifications
The F Series move materials between two or more levels. It feature four-corner support for heavy-duty, vertical material handling jobs. Principal components are guide columns, carriage and a mechanical lifting mechanism.
Lifts heavy, bulky oversized loads up to 50,000 lbs or more. Unlimited carriage sizes and vertical rise. Standard travel speed of 20 FPM (400 FPM+ available).
Guide columns are 6” wide flange. Carriage is fabricated of heavy-duty steel structural members with deck plate. Other surfaces can be supplied. Can be loaded/unloaded from all four sides.
Carriage is lifted and lowered by roller chain attached to an electric motor/reducer assembly mounted on the guide columns. Standard speed units employ 7-1/2 HP to 25 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.
Upward/downward travel of the carriage is controlled by a limit switch. When 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 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 SIDE GUARDS
Carriage is equipped with safety rails on non-operating sides and safety chains, gates or diagonal drop bars on operating ends. Optional expanded metal or sheet metal carriage side guards available.
Safety codes (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.
