Schwing SP 1800-D, Original Operating Instructions

Page: 87 / 390

Do not carry out more than one movement at a time. If a movement is
stopped, the entire volume of fluid is available for the remaining
movements, and can increase their speeds. Depending on the de‐
sign, it may be the case that carrying out several movements at once
(as opposed to carrying out a single movement at maximum speed at
any one time) does not bring any advantage in terms of time. Carry‐
ing out several movements at once requires an increased level of at‐
tentiveness.
Lock all supports mechanically, if this is provided for in the design.
Close all shut-off valves in the support hydraulics. Leaks can cause
the supports to sink on one side.
The machine must be made level in all directions. Provided the manu‐
facturer does not state otherwise, the maximum permissible deviation
from the horizontal is 3 °. Greater deviations from the horizontal over‐
load the slewing gear for the placing boom as well as its overall sup‐
port structure, jeopardising the stability of the machine.
Check stability regularly during operation. The elastic distortions to
the machine frame occasionally occurring under extreme positions of
the placing boom (one support foot lifts from the ground) must be
compensated for by resetting the support cylinders until all support
feet are firmly placed on the ground.
2.4.5 Driving
When preparing the machine for driving, you must perform the follow‐
ing tasks in particular:
● The placing boom must be folded in fully and positioned on the
placing boom support provided.
● The support legs and support feet must be fully retracted and se‐
cured.
● Raised or locked axles must be lowered and released.
