Unlike most A-frames, the TrestleHoist-2 can have it's two legs set to different lengths to allow the off-loading of a delivery truck followed by transporting the load to its final destination. The Model TH4-36x66 (Shown) allows the offloading of a standard service van.
When not in use, the TrestleHoist-2 folds compactly for storage. Because of the wheel design, the flattened device will usually prop up against a wall out of the way. Notice the winch. Unlike a traditional A-frame, the winch is mounted at the end of the beam and uses a lift pulley that can be positioned along the beam to do the actual lifting. This worm drive winch has the added ability to have the handle removed and be powered by a standard cordless drill. If no power is available, it can also be used manually. As standard, it comes with 18ft of 3/16 aircraft cable for optimum lift versatility.
Unlike most A-frames, the TrestleHoist-2 can have the vertical risers set anywhere along the horizontal beam. If you are lifting a tall but narrow object (like an XQF-50) the wheels can be positioned close to the unit for maximum maneuverability. The drop down pulley can be set on one foot increments including at the very end of the beam. This allows you to create a cantilever lift by placing counterweights on the winch end of the wheel assemblies.
The TrestleHoist-2 is versatile. The model shown can also be set up to have seven feet of clearance under the beam. Because the winch is located at the end of the beam, no height is lost under the beam or above it. This allows you to get into tight spaces and low overhead clearances with a minimum of fuss. The vertical risers can be exchanged with taller ones for higher lifts. The telescoping members have no metal to metal contact. They ride on delrin slides for smooth operation and all weather storage. The vertical risers can be set at three inch hight adjustments for optimum versitility.
