PRODUCT INTRODUCTION
Thank you for purchasing a fork-mounted Lift Master boom (“boom”, “product” or simply “LM”) made by Vestil
Manufacturing Corporation (“Vestil”). Our booms are durable, high-quality products that combine safety-conscious design
features and rigorous engineering. Although operation and use procedures are relatively intuitive, all persons who might
use or operate of this product must familiarize themselves with the instructions provided in this manual
.
Standard design features include: 2 fork pockets that receive the tines (forks) of a fork truck; 2 load attachment points
(hooks); and either a safety chain or safety strap to wrap around the fork carriage and prevent the boom from sliding off of
the forks during use. Dimensions of offered models, as well as other product specifications appear in the following table:
