Escalera ® Stair Climber stair climbing handtrucks are constructed of a tough tempered aluminum alloy, making the handtrucks stronger than magnesium, but lighter than steel. All Escalera Stair Climber handtrucks are 24" wide and range in size from 60" to 72" tall. Every Escalera Stair Climber ships with a sealed gel-cell battery, an automatic battery charger, and one automatic rewind safety strap. These units are built to order and the manufacturer is currently projecting a 3-6 week turnaround time for shipment.
