The farther forward the center of gravity moves, the smaller the load weight must be and the more likely the truck is to tip forward. It does this by adding its own weight to the load side of the fulcrum, and by moving the truck's load center forward. Normally, an attachment tends to move the center of gravity of the combined truck and load forward. In addition to the safety aspect - stability and avoidance of damage to the truck - you should assure yourself that the truck can do the work you need done. The capacity factor is important in your selection regardless of whether you are buying the truck with the attachment or are adding the attachment to a truck yourself. Their data reflects, in most cases, testing with specific trucks and attachments. But you should work closely with your truck manufacturer before making a decision.
#Forklift clamp trucks free#
Although free rigging is a common practice, it could affect the capacity and safe operation of a powered industrial truck.CAUTION: Formulas can give you a good ballpark estimate of how capacity will be affected. This type of lift does not use an approved lifting attachment. Free rigging is the direct attachment to or placement of rigging equipment (slings, shackles, rings, etc.) onto the forks of a powered industrial truck for a below-the-forks lift. See Forklifts: Free Rigging Requires Manufacturer's Approval, OSHA Standard Interpretation, (October 22, 1999).
The forklift nameplates must be changed accordingly.
#Forklift clamp trucks professional#
A qualified registered professional engineer must perform a safety analysis and address any safety or structural issues contained in the manufacturer’s negative response before granting approval. If no response or a negative response is received from the manufacturer, written approval of the modification/addition from a qualified registered professional engineer is acceptable. Capacity, operation, and maintenance instruction plates, tags, or decals shall be changed accordingly. Modifications or additions that affect capacity or safe operation shall not be performed without prior written approval from the forklift truck manufacturer. If the truck is equipped with front-end attachments other than factory installed attachments, request the truck be marked to identify the attachments and show the approximate weight of the truck and attachment combination at maximum elevation with load laterally centered. Inspect mechanical and hydraulic components and maintain in accordance with the manufacturer’s instructions. Tailor inspection steps to the attachment.Įxamine load-bearing components for deformation. Include attachments in a scheduled maintenance and inspection program. Treat an unloaded forklift with an attachment as partially loaded. Know the mechanical limitations of your forklift.Ĭhange capacity, operation, and maintenance instruction plates, tags, or decals when a forklift truck is equipped with an attachment.

Consult the operator's manual for instructions on how to use the new equipment.ĭo not exceed the rated capacity of the forklift/attachment combination. Retrain an operator if a new attachment is added to the forklift. Train operators in the fork and attachment adaptation, operation, and use limitations. The attachment increases the load center by moving the load further away from the balance or fulcrum point. The weight of the attachment reduces the lifting capacity of the truck. Attachments affect the truck's performance by changing its center of gravity, visibility, and capacity. Operators must be trained in the proper use of attachments because they alter the performance of the forklift. Personnel platforms specially designed for lifting personnel.
