Using Your Load Chart - Manitowoc Grove TMS800E13 Operator's Manual

TMS800E13 OPERATOR MANUAL
NOTE: Always operate the control levers with slow, even
pressure.
Preload Check
After the crane has been readied for service, an operational
check of all crane functions (with no load applied) should be
performed. Preload check is as follows:
• Extend and set the outriggers and level the crane.
• Raise, lower, and swing the boom right and left at least
45 degrees.
• Telescope the boom out and back in, ensuring all
sections extend and retract properly.
• Raise and lower the cable a few times at various boom
lengths. Make sure there are no kinks and that the cable
is spooling on the hoist properly.
CAUTION
Run the engine at or near the governed RPM during
operation of all crane functions.
NOTE: Carefully read and become familiar with all crane
operating instructions before operating the crane.

Using Your Load Chart

NOTE: One of the most important tools of every Grove
Manitowoc crane is the Load Chart found in the
crane operator's cab.
R e f e r t o F i g u r e 3 -1 9 f o r t e r m s t o k n o w i n
determining lifting capacities.
The Load Chart contains the lifting capacities of the crane in
all allowable lifting configurations, and must be thoroughly
understood by the operator.
The Load Chart is divided into capabilities limited by crane
structural strength and stability which is shown by a bold line
GROVE
OPERATING CONTROLS AND PROCEDURES
across the chart. Structural strength limits are above the line
and stability limits are below the line.
The left column is the load radius, which is the distance from
the axis of the crane rotation to the load center of gravity. The
top row lists various boom lengths from fully retracted to fully
extended (with swingaway extension). The number at the
intersection of the left column and top row is the total load
limit for that load radius and boom length. The number in
parentheses below the total load limit is the required boom
angle (in degrees) for that load. Boom lengths between
increments should always be treated as if it were the next
longer length. For example, if the actual boom length is 15.2
m (50 ft) and the chart shows boom lengths of 14.6 - 16.4 m
(48 - 54 ft), use the load capacity shown in the 16.4 m (54 ft)
column.
Another important section is the range diagram. The range
diagram shows the operating radius and tip height that can
be achieved at a given boom length and angle. If the
operator knows the radius and tip height required for a
specific lift, the angle and boom length can quickly be
determined from the range diagram. Or if he knows the boom
length and angle, he can quickly determine the tip height and
operating radius.
A lifting diagram is included for over-side, over-rear, and
over-front lifting areas. The lifting area diagram shows that
the locations of the outrigger stabilizer cylinders in the full
extended position are used to mark the boundaries of the
lifting areas.
Another section contains notes for lifting capacities. Be sure
to read and understand all notes concerning lifting
capacities.
The Load Chart also gives weight reductions for Manitowoc/
Grove load handling devices such as hookblocks, overhaul
balls, jib sections, etc, which must be considered as part of
the load. The weight of any other load handling devices such
as chains, slings, or spreader bars must also be added to the
weight of the load.
