There is a huge difference between carrying it up a ladder to the loft and pushing a button and watching it go there by itself. Somewhere in between, a part-time mechanical helper arrives to take the grunt out of grunt work and then goes away until the next challenging hoisting or lifting job. Not only can this clever unit hoist heavy boxes into attics and second-story loft openings, but it can lay itself right down on a stairway to take heavy loads upstairs -- safely and reliably.
This unit uses an extendable aluminum ladder as a portable railway and a rugged trolley to control loads while they are being lifted or lowered. A compact electric hoist with a remote hand control module allows the user to precisely control movements either while raising or lowering loads. The unique feature of the system is that it easily adjusts angles to steep ladder-like climbs or shallow ascents for stairways. A lift-actuated safety latch senses whether the load is being supported by the cable or not. If any aspect of the drive train or cable let go, the latch immediately engages the next step and locks the load there. A manual hand-winch backup allows the load to be lowered until the problem can be ascertained.
Cable Hoist Strategy
A 220-pound single cable electric hoist attached to the bottom of the ladder rails lifts the trolley along the track via a single direction-changing cable pulley at the top of the ladder. The hoist uses 115 VAC wall current. It has up-and-down push-buttons on the wired remote-switch, handheld module. The trolley has six polypropylene rail wheels with three being evenly spaced on each side. The load platform is covered with a high-traction mat tread and has a continuous channel to allow strapping or tying down critical loads. It also tilts to any of 10 different angle settings to allow slightly negative camber lifting under all ladder-lifting situations. In other words, the platform always tilts slightly toward the ladder so the load will not come off. Two small bubble-level vials indicate zero tilt or negative five-degree tilt angles.
Two extra sections that are four feet long may be added to its 16-foot-long base to bring the total ladder rail length up to 24 feet. The ladder base has retractable wheels that allow you to roll it into position at the lifting site.
Using the Multi-Hoist as a Ladder Lift
For ladder-like use lifting heavy items into attics or lofts, lean the ladder against the side of the building. Attach the electric hoist winch to the bottom of the ladder. Extend the self-locking pulley with the two cable lengths to the top rung of the ladder. Connect the loose end of the cable to the trolley. Adjust the trolley platform to the negative five-degree position. Load the cargo onto the trolley platform and operate the lift.
The difference in operation on a stairway is that the angle is lower, with the ladder assuming approximately a 45-degree angle. Adjust the trolley’s platform angle to set the negative 5-degree angle, and proceed as with the ladder.
