    Do not attempt to lift or drag a load from the side! The boom can fail far below its rated capacity. WARNING Do not weld, modify, or use unauthorized components on any Auto Crane unit! This will void any warranty or liability. Also, failure of the crane may result.

  • Page 8: Introduction

    The cranes are attached to your 12-volt truck electrical system. The crane is another highly efficient Auto Crane product. The use of a maintenance-free battery is not recommended on any Auto Crane product. The recommended alternator and battery that will give the longest life with the most useful duty cycle is a 60-amp alternator with a 500 cold cranking amp battery. These specifications should be considered minimum.
