Bucket truck parts are designed to be tough. The manufacturer intended this to allow the truck to perform work efficiently. One of the modified versions of these vehicles is used for material handling. This type of equipment is growing in popularity because of its capability to elevate both the crew and heavy loads. This is made possible through two useful parts designed for such usage which are the winch and the jib. Lifting Capacity Most material handlers have a jib with a small winch and boom to achieve more lifting capacity than a regular bucket truck. Operators must have additional knowledge about boom angles since the truck’s holding power greatly depends on this factor. The lifting capacity of these handlers ranges from 1,500 to 2,000 pounds for a maximum load. Usage Adding a light duty jib crane to the boom tip enables a crew to hoist material up to the actual aerial working place. The jib crane acts as an additional hand to the operator and is very useful for lifting and positioning. It is typically used by the electric utility industry to handle items such as transformers that need to be raised. Lifting Factors The upper boom's lifting capacity changes as the boom angle varies. As the upper boom approaches a vertical position, or 90 degrees, its lifting capacity increases. In this position, the higher arm is at its greatest lifting capacity. When the boom is positioned horizontally, or 180 degrees relative to the ground, the lateral stress on the boom increases. In this position, the upper boom is at its lowest pulling power position. The lower boom's raising capacity changes with different angle positions as well. With the arm's vertical stance, the elevating ability increases and in this position the boom can achieve its greatest raising potential. In a horizontal stance, the lifting capacity decreases. Winch Another important bucket truck part that is used for material handlers is the winch. These devices are basically a line that can be attached to another object in order to move from one place to another. For bucket trucks, winches are used to pull or move material towards the truck. This piece of equipment can be operated through combustion, hydraulic or electric engines. Safety in Operation The following are some practical ways to be safe during material handling: Be Sure Vehicle is Stationary - Make sure the vehicle is immovable when performing any lift, unless the bucket truck has been otherwise certified according to ANSI standards or the manufacturer’s certification. Be Sure to Set Brakes, Outriggers and Chocks - Bucket trucks should be stable by setting the brakes, outriggers and wheel chocks. Flags or cones can be used to alert surrounding traffic that there is an ongoing operation in the area. Do not compromise load limits; the job should be stopped if a malfunction occurs. Follow Standard Safety Procedures - Bucket crews should not attempt to use any device or other platform to reach the working area while inside the elevated bucket; feet should remain firmly on the bucket floor. Harnesses should be worn for fall protection. Check Overhead Clearance - When working near electrical lines, check the overhead clearance. Bucket crews must wear insulated gloves and other gear that is designed for good insulation. Always refer to the manufacturer’s recommendation for the lifting capabilities of the equipment. Efficiency can only be achieved if the equipment is utilized properly. Workers when operating a bucket truck need to know how to properly use the winch and the jib for best material handling usage that will raise heavy material! Christopher M.
