SUPERSTRUCTURE
TMS9000-2 SERVICE MANUAL
3.
Tighten the screw against the spring load until the
locking pin (1), (Figure 4-31) is pulled in as far as it will
go and is situated behind the side wall of the telescopic
section.
4.
Unlock the other side of the telescopic section using the
same procedure.
Once the pins are retracted, use your external means
(second crane, forklift, etc.) to retract that section and then
remove the bolts to pin that section in a retracted state. Move
to the next section to be retracted (as necessary).
Locking Telescopic Sections
1.
Retract the telescopic section until the locking pin (1),
(Figure 4-31) is in the middle of the opening.
2.
Remove the screw from the bore hole (4), (Figure 4-31).
The locking pin (1), (Figure 4-31) is then pushed out of the
opening due to spring tension.
3.
Install the grease fitting into the bore hole.
4.
Retract the telescopic section until the recesses (2),
(Figure 4-31) have been set down on the telescopic
section (3), (Figure 4-31) above it.
NEW YORK HOUSE LOCK
The New York House Lock is designed to meet the New York
regulations for a mechanical locking of the superstructure. It
is not intended for other applications, such as traveling with a
load, etc.
It operates with an electrical actuator Up = disengaged
(unlocked) and down = engaged (locked). It can be operated
by either the super cab display or by the hand held remote.
There are 2 proxy switches, one for fully disengaged
(unlocked) and one for fully engaged (locked). This can be
seen on the screen of ODM display or remote.
BLEEDING THE TELESCOPING CYLINDERS
There are two vent screws on the telescoping cylinder for
bleeding the cylinder chambers. The vent screws are
accessible through hand holes in the telescopic sections.
Prerequisites
With the following requirements it is assumed that no lattice
extension is rigged.
•
Park the truck crane on a level surface.
•
Support the truck crane with at least the outrigger span
: 7.00 m X 5.61 m (22.97 x 18.4 ft).
•
Remove the counterweight.
•
Enter the RCL rigging code for the current rigging mode
of the truck crane.
•
Completely retract all telescopic sections.
•
Unreeve the hook block.
•
Swing the superstructure to the rear or to the side.
•
Lower the boom into a horizontal position.
Bleeding Procedure
Carry out the bleeding procedure on all vent screws in turn.
•
Remove the cap from the relevant vent screw.
•
Place a transparent hose onto the vent screw. Hold the
other end of the hose in a container filled with oil.
•
Loosen the vent screw by 1 – 2 turns.
•
Carefully drain the telescoping cylinder of hydraulic oil
until the oil flowing through the hose no longer contains
any bubbles. Carefully extend the relevant telescopic
section in the direction specified.
The oil collected in the container must not be used again as it
contains air.
CAUTION
Released Lock Hazard!
Under no circumstances may you operate the telescoping
cylinder as long as the lock is mechanically released.
Therefore unscrew all screws out of the bore holes
immediately after finishing the repair work.
In this way, you prevent the telescoping cylinder from
hitting the locking system and consequently damaging it.
Do not unlock a section and then boom up until it slides in.
Damage to equipment will result.
CAUTION
Free Swing Hazard!
The New York House Lock is strictly an additional backup
device. The swing brake must always be installed.
Equipment damage or injury possible.
