Simply slide the forklift tines into the sleeves under the platform, secure it, and the lift truck is converted to a portable manlift. The platform is diamond plate with formed 4" toe-boards. The unit is secured to the lift truck with a tine lock, a mechanism that rotates up behind the left forklift tine, preventing the platform from sliding forward off the tines. In addition, a chain with a hook is welded to the base, which wraps around the lift column of the lift truck and hooks back to itself or to the platform.
