Between Floor Lift

PLM/2P/1500/2850/B/G Double Pillar Between Floor Lift

This Double Pillar Between Floor Lift has a Safe Working Load of 1500 Kgs and a lift height of 2850mm. The lifting platform was big enough to allow a standard pallet (1200 x 1000mm) to be loaded using a hand pallet truck. At the upper level, there was a landing plate to allow easy unloading. The Between Floor Lift was manufactured from mild steel with a powder coated finish and is a welded construction throughout. The Between Floor Lift was designed to be bolted to the floor without the need for a pit. The lifting is accomplished via chains driven by a motor gearbox mounted at the top of the one column with a crossover shaft to the other column.

To suit the plant layout, the pallets were loaded and unloaded from the same side of the lift at the lower and upper levels. To fit within the space available at the end of the mezzanine floor, the main columns of the Between Floor Lift were mounted at the rear of the between floor lift on the opposite side to the loading doors. The Between Floor Lift was made in two sections which were assembled on site during installation. There was ramp fitted at the ground floor and a landing plate and ramp on the mezzanine floor level.

Safety Guard to BS EN 14120:2015 Safety of Machinery Guards

The safety guard is constructed from 40 x 40 x 3mm box section and 2mm sheet to meet the guidelines of BS EN 14120:2015 Safety of Machinery Guards. This guard will reach to a height of 2200mm above the upper floor level, having a pair of hinged doors at each level through which the Between Floor Lift can be loaded and unloaded. Each door is electrically interlocked to prevent the between floor lift being operated with a door open and in addition, the doors are mechanically locked closed whilst the between floor lift is running. Each door may only be opened when the lifting carriage is at the appropriate level. The guard doors can be meshed with 25 x 25mm mesh if preferred at no additional cost.

Between Floor Lift Electrical Control

This Between Floor Lift is fitted with an IP65 Stainless Steel Control Panel which is mounted on the safety guard at a convenient position to give good maintenance access under the Provision and Use of Work Equipment Regulation 1998 (PUWER). The control panel incorporates the following controls; Up, Down, Guard Release, Emergency Stop, Cleaning Key Switch and a Reset Facility. There will be a remote push button station at the upper level incorporating the following controls; Up, Down, Guard Release and Emergency Stop.

The between floor lift operation is latched so that pressing the respective ‘Up’ or ‘Down’ push buttons once will raise or lower the lift to the other floor level. Each time the Lift Carriage activates the upper limit switch, an electrical actuator will be driven out underneath the lift carriage to support it while it is loaded. Before the lift can move again, the actuator will retract automatically once the down button is pressed.

Between Floor Lift Cleaning System

This cleaning system will be fitted to your Between Floor Lift during manufacture to allow access to the floor beneath the lift carriage for cleaning. The cleaning system will operate as follows:-

• The lift frame must be empty, at the full up position and the safety guard gate must be closed
• At the full up position, the lift carriage is prevented from falling by a 50mm support bar driven out beneath the lift carriage using an electrical actuator
• As the bar is engaged, it will alter the state of 2 off separate safety limit switches
• The one switch will disable the between floor lift safety circuit and relay
• The second limit switch will allow the lower safety guard door to be opened providing that the Cleaning Key Switch has been operated
• It is now safe to enter the lift enclosure for cleaning purposes with the between floor lift disabled and the lift carriage supported
• Once cleaning is complete, the above sequence is reversed
