Here’s a short video from Prime Alliance Marketing on some of the features of the Presto LiftStik Series of Lifter-Transporters. There’s never been a more versatile lifter/transporter than the LiftStik series from Presto. With capacities ranging from 185 lbs to over 400 lbs, there’s almost nothing these sleek, attractive, user-friendly machines can’t do.
Lift tables are used to raise and position workpieces for ergonomic access. They are used for material positioning, load positioning, or lifting in applications such as construction, automotive and garage service, electrical and power service, telecommunications, manufacturing, and inventory management. Lift tables are also used in the wire and cable industries and in other applications, such as painting, where access to above ground locations is required. Important specifications for lift tables include lift capacity, vertical lift travel, platform width, platform length, and actuation method. Lift capacity is the maximum force or load supported by the lift. Vertical lift travel describes the difference between fully lowered and fully raised lift positions. Platform width is the narrow dimension of the lift platform. Platform length is the long dimension of the lift platform. Lift tables may be actuated by hand cranks, screw drives, foot pumping and ratcheting, pneumatic air cylinders and air motors, hydraulic cylinders and motors, or electrical motors.
There are a number of mechanisms by which industrial lift tables may be raised or lowered. These include scissor lifts, screw lifts, rack and pinion lifts, telescoping lifts and articulated lifts. Scissor lifts use linked, folding support members to achieve lifts. The lifting action occurs when the members are drawn together, typically with a screw mechanism. Screw lifts employ the mechanical advantage of threads to lift a workpiece vertically. Rack and pinion lifts function via a small drive gear (pinion) that drives a straight-toothed rack to lift the load. The telescoping lift mechanism has multiple sections that retract and extend into and out of each other. Articulated lifts have multiple sections that unfold or articulate to lift a platform or bucket. Frequently, cherry pickers are articulated lifts.
Features common to lift tables include tilting, rotating, counterbalance, wheels, hand or safety rails and truck mounting. Lift tables may have tilting and rotating functions in addition to lifting. A counterbalance is a weight feature on load lifts to prevent lift overturning without relying on legs or supports under the load. They may also come equipped with wheels to provide rolling for load transport and positioning; typically equipped with a brake or stabilizing outriggers. Hand and safety rails provide for personnel safety or to prevent load from falling or sliding off the lift.
PALLET LOAD LEVELER
A new hydraulic load leveler for use in the manual loading and unloading of pallets has been introduced by Presto Lifts Inc.
The P4™ improves worker productivity and reduces fatigue. Its platform lowers to floor height so that pallets can be placed and removed using a hand pallet truck.
In loading operations, a pallet is placed on the platform and the platform is raised by hydraulic power to its full “UP” position. As goods are loaded onto the pallet, the platform is lowered so that each succeeding tier of goods can be loaded at the same height.
When unloading pallets, the platform starts at its lowest height and is progressively raised so that each succeeding tier of goods can be removed at the same height.
When unloading pallets, the platform starts at its lowest height and is progressively raised so that each succeeding tier of goods can be removed at the same height.
The P4 can be accessed from all four sides. Units are equipped with a photoelectric toe guard which will stop downward travel if the beam is interrupted.
The units have capacities up to 4000 lbs., making them suitable for most pallet loads that can be moved with hand equipment.
SCISSOR LIFT TABLES FOR A VARIETY OF USES
Presto Lifts Inc. offers a complete line of scissor lift tables for a wide variety of uses. Standard Duty lifts are available with capacities from 2000-6000 lbs. with platform sizes up to 48”x88” and satisfy most application requirements.
Special requirements can be accommodated by special use units. Light Duty lifts are available in 1000 & 1500 lb. capacities in both electric and manual lift styles. Portable lifts feature DC Power, can be easily moved from location to location and can be equipped with single or double high lift mechanisms. Many units are also available with pneumatic actuation.
SKID LIFTER IS A TRANSPORTER/WORK POSITIONER
Presto Lifts, Inc. announces the availability of a new skid lifter. Designed to pick up a load on a skid or open-bottom pallet, the Presto Skid Lifter can transport the load to a workplace and then raise it to a convenient working height. It is ideal for feeding presses, binders, cutters, conveyors and a wide variety of production machines.
The unit has a 3000-lb. capacity and a raised height of up to 32”. Lift is achieved by a two-speed manual pump. For loads under 600 lbs., the unit automatically goes into “Quick Lift” mode so the forks can be raised the full 32 in just 18 strokes of the ergonomically designed steer handle. For heavier loads the unit shifts to “Ergo Lift” mode, raising the forks to full height in 55 strokes. Automatic load stabilizers prevent the unit from being moved when the load is raised. Standard forks are 45” long with an outside dimension of 27” or 20.5”.
PNEUMATIC LOAD LEVELER AUTOMATICALLY ADJUSTS PALLET HEIGHT AS BOXES ARE ADDED OR REMOVED
The P3™ Pneumatic Leveler from Presto Lifts Inc. allows operators to build or break down pallet loads with a minimum of bending, reaching, stretching, or walking around. The unit automatically adjusts the height of pallets as boxes are added or removed. Height adjustment is achieved by a heavy-duty reinforced rubber airbag combined with a permanent spring.
Because the P3 is pneumatic it can handle a widely varying pallet load weights (from 400-4,500 pounds). It can be used anywhere that shop air is available.
A large turntable equipped with anti-friction bearings allows loads to be quickly and effortlessly rotated so that operators can always be working on the nearside of the pallet.
The extra-wide base means no lagging is necessary, and fork pockets allow the unit to be easily relocated by a fork truck or stacker.
SLEEK, STYLISH, ERGONOMIC WORK POSITIONERS
Long known as the leader in manual stackers, Presto Lifts Inc. introduces the availability of a new line of fully powered stackers. With lift heights of 62”, 101”, 125” and a full 2,200 lbs. capacity, the new Power Stak™ line is loaded with ergonomic features. Narrow mast design and offset control handle, provide operators with a clear view of what’s in front of them with virtually no blind spots. An ergonomically designed handle puts all controls within easy read for maximum operator comfort and convenience. Forward and reverse drive “thumb” switches are located on both sides of the handle to accommodate left or right hand operation. An auto reversing belly switch protects operators from potential injury when walking the unit backwards while an automatic brake immediately halts travel when reversed.
The Power Stacker is built on an extremely stable, yet short wheel base to provide maximum maneuverability even in tight quarters. Power is achieved via two 12-volt maintenance free batteries. A 110-volt built-in charge is also a standard feature. Units are available in fork-over design for use with open bottom pallets, or adjustable straddle design for use with closed bottom pallets.
POWERED STACKER IDEAL FOR TIGHT SPACES
