Preventing Overturning And Tipping - Jungheinrich DFG 316s Betriebsanleitung

Be especially careful when tilting the load forward or back, especially when stacking
at great heights. Lifted load carriers may be tilted forward only to set down the load
during stacking, or to deposit a load on a shelf or a rack. The load must be tilted back
until it is stabilized for stacking or depositing.
Qw W
The handling of loads suspended from a crane boom or other equipment can
induce dynamic forces, which may adversely affect the stability of the
industrial truck and may not comply with the manufacturer's requirements in
accordance with ASME B56.1-2004. Tilting the load, sudden acceleration,
braking, and turning can cause the load to swing and be dangerous.
When handling suspended loads:
– The load capacity of industrial trucks designed for transporting suspended goods
as defined by the manufacturer must not be exceeded;
– The load must be raised vertically and must never be pulled in a horizontal
direction;
– When transporting the load, the bottom of the load and the lift mast must be
positioned as low as possible;
– When the load is raised, the truck must be maneuvered slowly and carefully; the
operator must limit the vehicle to movements allowing the load to be lowered into
the transport position;
– Where possible, use guide ropes to prevent the load from swinging.
Transportation of liquids:When transporting liquids, the center of gravity can vary
according to the movement of the industrial truck, and this can have a very adverse
effect on the vehicle's stability. All necessary precautions must be taken when
maneuvering; accelerating, braking and tight corners should be avoided where
possible, as should any sudden movement.
Flattened wheels:If the vehicle has been parked for a lengthy period of time, the
running surfaces of the wheels may become flattened. This does not adversely affect
the safety or stability of the vehicle, however, since the flattening will disappear once
the vehicle has been driven for a short distance.

Preventing overturning and tipping

Special safety precautions are required when operating a high-lift industrial truck with
counterweight and central controls where the driver has a fixed driving position:
1. A laden or unladen truck can tip over if the driver does not brake to a safe speed
before a bend. The following signs indicate that a truck is approaching a bend
too fast:
– Wheel slip;
– Tilting to one side;
– Lifting off of a tire
