Special controls such as automatic devices should be identified, preferably according to
the recommendations in Figure 3-6.
When a function is controlled by a pair of push buttons, they should operate in the same
sense as the lever controls. For example, pushing a button located to the rear (relative
to the operator’s position) should serve the same function as moving a control lever to
the rear.
3.16 Clamp Open Control
Effective October 7, 2010, safety standard ANSI/ITSDF B56.1, Section 7.25.7
covers all lift trucks with a load bearing clamp (paper roll clamp, carton clamp,
etc.), and requires the driver to make two distinct motions before opening or
releasing the clamp. For example, you must press a switch and then move a
lever to unclamp the load. This requirement applies to new and used attachments
being mounted on trucks which shipped from the factory after October 7, 2010,
and is a recommended feature to be installed on dealer orders and existing
applications.
WARNING
Load loss hazard.
Injury or equipment/load damage may result if a fork
positioner attachment is used to clamp a load. The fork
positioner does not have enough clamping force to safely
hold a load.
Always support the load with the forks. Do not use fork
positioning attachments as clamps.
