The LTA5512E is the preferred aluminum model for moving grills, spas, and stoves. It has a 1200 lb/544kg weight lift capacity. The built-in leverage bar allows you to obtain better leverage when using your LECTROTRUCK. Adjustable strap bars can easily be attached, moved and detached without the use of any tools. This model also features a user friendly, detachable, battery pack. Two clips located on the sides of the battery pack quickly release, so you can remove the entire battery pack without removing your load from the LECTROTRUCK. The battery pack also has a built-in battery charger, so all you need to do is bring the power cord to your battery pack. Each unit includes two flat strap bars and a battery charger.
