OPERATING CONTROLS AND PROCEDURES
3
Attaching the Load
The hoist rope must not be wrapped around the load as the
wire rope will be damaged.
The load must be attached to the hook by means of slings or
other devices of sufficient capacity.
Holding the Load
The operator must not leave the controls while a load is
s u s p e n d e d . A n e x c e p t i o n t o t h i s i s u n d e r t h o s e
circumstances where a load is to be held suspended for a
period of time exceeding normal lifting operations, the
operator may leave the controls provided that, prior to that
time, the appointed individual and operator establish the
requirements for restraining the boom hoist, telescope, load,
swing and outrigger functions, and provide notices,
barricades or whatever other precautions may be necessary.
No person should be permitted to stand or pass under a
suspended load.
Moving the Load
1.
The person directing the lift must see that:
a.
The crane is level and where necessary, blocked.
b.
The load is well secured and balanced in the sling or
lifting device before it is lifted more than a few
inches.
c.
The lift and swing path is clear of obstructions.
2.
Before starting to lift the load, the following conditions
should be noted:
a.
That the boom when extended, is laterally straight.
b.
That the hoist rope is not kinked or damaged.
c.
That multiple-part lines are not twisted around each
other.
d.
That the hook is brought over the load in such a
manner as to minimize swinging.
e.
If there is a slack condition in the wire rope, it must
be determined that the rope is seated on the hoist
drum and in the sheaves as the slack is removed.
f.
The effect of ambient wind on the load and crane
stability.
3.
During lifting operations care must be taken that:
a.
There is no sudden acceleration or deceleration of
the moving load.
b.
Load, boom and other parts of the crane do not
contact any obstruction.
4.
The load must not be lowered below a point where less
than three full wraps of rope remain on the hoist drum.
5.
When two or more cranes are used to lift one load, one
designated person shall be responsible for the
operation. That person must analyze the operation and
instruct all personnel involved in the proper positioning,
rigging the load and the movements to be made.
Decisions such as the necessity to reduce crane ratings,
load positions, boom location, ground support and
speed of movement must be in accordance with this
determination.
6.
When rotating the boom with a load, sudden starts and
stops must be avoided. Rotational speed must be such
that the load does not swing out beyond the radius at
which it can be controlled. A tag or restraint line must be
used when rotation of the load is hazardous.
Traveling with a Load (Pick and Carry)
NOTE:
Pick and carry is not allowed when the boom
extension is attached and used to lift the load.
When traveling with a load, a designated person must be
responsible for the operation. Decisions, such as the
necessity to reduce crane ratings, load position, boom
location, ground support, travel route and speed of
movement must be in accordance with that person’s
determination. Specified tire pressure must be maintained.
The boom should be carried in line with the direction of travel
Sudden starts and stops should be avoided. Tag and
restraint lines should be used to control swinging of the load.
Turning Clearances
The front end of the boom extends beyond the end of the
frame. The operator must be aware of the maximum sweep
of the boom when turning and allow for adequate clearance
between boom and other objects.
Machine Shutdown
1.
Park the crane on level ground.
2.
Place the travel select lever in Neutral (N) and engage
the parking brake.
3.
Lower any load to the ground and full retract and lower
the boom.
4.
Turn the ignition switch to the OFF position and remove
the key.
