GENERAL SPECIFICATIONS
Sequence of Operations for Vertical Reciprocating Conveyors that Comply with ANSI/ASME B 20.1
FlorLIFTs are constructed with all steel framework and platform designed in accordance with conservative engineering practices.
FlorLIFT raises and lowers a steel platform with ball bearing steel roller wheels in guided 4" steel channels - using a single acting hydraulic ram coupled to an electric pumping unit, using two lifting chains alloy hardened heavy duty single strand roller chain.
OPERATION OF UNIT: Push the button, motor pumps oil and lifts cylinder. Push the down button, oil returns to tank and lift descends to first floor. Each chain travels over two steel sprockets that are mounted in a leveling cross head and attached to the cylinder; this crosshead levels the lifting platform. The chains are welded to the cylinder rises, the chains pull the platform to the desired height.
CONTROLS: Controls are either constant pressure or momentary contact call and send. One control at each level is either call or call and send with lighted switches.
POWER: 208/230 single phase or 3 phase 60 HZ.
SAFETY FEATURES
SLACK CHAIN SWITCHES: To prevent accidents, we installed an electrical slack chain switch. As the lift descends, if the chain slacks one inch, the slack chain shuts off the power and the cylinder and the lift stops immediately. Push the up button and the lift will rise and whatever is obstructing the unit underneath has to be removed and then the lift will work properly again. Then and only then will it descend.
PLATFORM SAFETY FALLING DEVICE: If the slack chain switch fails, then the platform safety falling device comes into action. Should both chains break simultaneously, the slack chain switch would not work, but when the chains break, the lift will fall about 3 or 4 inches. The platform safety device is mounted on the lifting platform carriage. It has self-generating type cams, spring loaded and have machine hardened teeth which rapidly engage the mast uprights, dig in hard and deep and hold the lifting platform and prevent the load from falling.
LIFTING CHAIN: Two single-strand, alloy, hardened, heavy duty, and roller. LIFTING TYPE are each capacities to sustain many times total rated load capacity of lifter. Chains attached at one end at OUTER EDGES OF LIFTING PLATFORM to provide extra load stability, are mounted over chain LOAD ROLLERS carried in an equalizing type RAM CROSS HEAD and at the other ends are attached to MAIN FRAMEWORK with adjustable anchor TAKE-UPS. Each chain is capable of supporting the entire load and has an ultimate breaking strength of 7,000 lbs. each - a total of 14,000 lbs.
HOSE: Hose leading from pumping unit to the cylinder has a bursting strength of 7,000 lbs.
FOLDING GATES: Manually operated. At each entrance or exit is a folding gate. Gate is equipped with an electrical mechanical switch. Lift will not operate if gates are open.
SAFETY FLOW VALVE: Safety flow valve is mounted at the bottom of the cylinder and adjusts the descending speed of the lift. Attached to this is a hose that goes to the pumping unit. Should the hose break or develop a leak, the safety flow valve keeps the lift from falling and descends at the rate of 15 feet per minute. Hand lowering valve - In the event of power failure, the lift can be let down by a hand lowering valve on the pumping unit.
SAFETY RELIEF VALVE: The unit is designed to lift between 750 to 1000 lbs. If the lift is overloaded, it will not go up until the proper weight is reached.
SAFETY DOOR LOCKS: At each opening, there will be an electric door lock which prevents the door from opening until the platform has reached that height. Should the door be left open, the lift will not leave that floor until the door is closed.
LIMIT SWITCHES: The unit is equipped with upper and lower limit switches to prevent over-travel. The hydraulic cylinder is also designed to prevent over travel.
HAND LOWERING VALVE AND PUMPING UNIT: FlorLIFT is equipped with a hand lowering valve to be used only in an emergency. If power is lost, the hand lowering valve is used to lower the lift to the lowest floor. The pumping unit must be remote and placed outside the shaftway for easy access to use the hand lowering valve or any electrical repair. No one should be under the lift when using the hand lowering valve.
The lift has been approved as a material lift under B 20.1 ANSI/ASME in most states. It is your responsibility to obtain permits from your local elevator department or building department.
All FlorLIFTs are custom-made to suit your needs in regards to platform size, height and special equipment.
FLORLIFT OF NJ, INC. RESERVES THE RIGHT TO CHANGE SPECIFICATIONS AND/OR FEATURES
Our FL-102 vertical reciprocating conveyor is installed under ANSI/ASME b 20.1 - Under the code, there is no riding switch. Riding the conveyor shall be forbidden to all personnel. Warning signs to this effect should be prominently posted at each point of access and at each point of operation. The sequence of operation is as follows.
The operator can call or send the unit to any floor from outside the shaftway only. No riders or personnel are allowed to ride the lift. All doors are equipped with electro-mechanical interlocks. If shaftway doors are open, the unit will not operate. If a folding gate is provided, the folding gate is provided with an electrical limit switch. If the doors or gates are open, the unit will not operate until all doors and gates are closed or locked. The pumping unit must be installed outside the shaftway. In the event of complete power failure, the pumping unit is equipped with a hand lowering valve so the unit can be lowered to the lowest point. The emergency hand lowering valve is to be used only in the event of power failure.
