Note!
Please see the Definition of 'inspection' and 'examination' below.
Inspection:
Looking at the crane for defects and checking the operation of the controls, limiting and indicating devices without loading the crane.
this is much more than a check but does not normally require any part of the crane to be dismantled other than removal or opening
of covers or housings.
Examination:
Verification that the crane can safely continue in service including a functional test of all safety devices i.e. limiting, indicating
equipment, brakes, clutches, safety valves etc to verify that they operate within the required tolerances. An examination is more
thorough than an inspection.
5. ASSEMBLY/STORAGE INSTRUCTIONS
5.1
ASSEMBLY.
a)
Attach the rear support (no.02) to the main post assembly (01) using four M10 - 21mm bolts (29) with four split washers (30).
b)
Attach the two swivel castor wheels (12) to the rear support using a large spacer washer (34), followed by a split washer (33) and an
M16 nut (32).
c)
Attach the small wheels (45) to the two 'u' shaped brackets on the lower front edge of the main support using two M8 - 45mm bolts
(39) and secure each with a split washer (40) and nut (41).
d)
Attach a wheel (12) to each leg (03 & 04) using an M10 - 45mm bolt. secure each with a split washer (43) followed by a nut (44).
e)
Lay each leg in turn (03 & 04) into the channels either side of the main support (01). secure each leg with an M10 - 70mm bolt (38)
remembering to use a split washer (31) in each instance.
f)
Assemble the leg locking pins (see item f) by screwing a knob (16) to an Ø18mm - 85mm long pin shaft (14) and push a 'c' clip (17)
into the groove on the locking pin. Ensure that the locking hole in each leg is aligned with the two holes in the channels and insert a
locking pin completely through each leg and the frame. retain each locking pin by inserting an 'r' clip (18) through the hole in each
locking pin.
g)
Attach the bracket (09) to the base of the hydraulic unit (08) using three M10 - 30mm bolts (49), three split washers (50), and three
nuts (51). then attach the hydraulic unit assembly to the bracket on the main upright using an M14 - 65mm bolt (35), secured with a
split washer (36) and a nut (37).
h)
seek help from another person when attaching the jib to the top of the main post. Align the holes at the back of the jib with the
holes in the top of the post and insert an M20 - 100mm bolt (24). secure the bolt with a split washer (25) and a nut (26).
i)
Position the ram piston in between the jib bracket and align the hole in the top of the piston with the holes in the bracket and
connect the two together using an M16 - 90mm bolt (21). secure the bolt with a split washer (22) and a nut (23).
j)
Assemble the jib locking pin (see item B) by screwing a knob (16) to the Ø12.5mm - 90mm long pin shaft (15) and push a 'c' clip
(19) into the groove on the locking pin.
k)
slide the jib extension (06) into the jib (05). Align one of the holes in the extension with the
holes near the end of the jib and retain it by inserting the jib locking pin. secure the jib
locking pin by inserting an 'r' clip (18) through the hole in the pin. further lock the jib by
inserting the locking bolt (27) into the hole in the top of the jib including a split washer (28).
l)
fasten the hook assembly (see item A ) to the end of the jib extension with an M12 - 70mm
bolt (46). secure the bolt with a split washer (47) and a nut (48).
m)
check that all fastenings, nuts and bolts are tight before using the crane.
5.2
BLEEDING THE HYDRAULIC SYSTEM
Before being put into use the hydraulic system must be bled to ensure that no air remains
in the system that may have gathered during transit.
a)
remove the rubber filler plug from the body of the hydraulic cylinder.
b)
the release valve is spring loaded so that it always automatically closes when released.
Get someone to hold the release valve open against the spring pressure by
approximately a 1/4 to a 1/2 turn. Pump the hydraulic unit 7 or 8 times to expel any air
and allow the valve to close. continue pumping until the boom has raised by about 50cm.
c)
Before replacing the rubber filler plug check that the oil level is just below the filler hole. If
the oil needs topping up this must only be done with good quality hydraulic oil such as
sealey Hydraulic Jack oil.
notE. Always allow the release valve to close automatically under spring pressure.
Do not tighten it when it has shut as it may then become difficult to 'crack' open.
5.3
STORAGe.
a)
Always store the crane fully closed so that the jib is in lowest position and the ram is
closed as shown in fig.2.
b)
to save space the legs may be folded into the upright position and secured in place using
the Lock Pins as shown in fig.2
.
