3.2 Counter weight drawings
The ballast has two specifications,PHZ3000A and PHZ2000,both are cast with reinforced concrete.
For specific dimensions, refer to Fig. 3.2-1a、3.2-1b、3.2-2a、3.2-2b
In the hand book, the size of the Counter-weight is designed as the density is 2400kg/
m3 . It is permited that the direction of the thickness should be adjusted if the density is
not the same to 2400kg/m3.
We suggest weight every ballast exactly, and make the lasting sign on the surface
of them. Permitted weight deviation is 2%, concrete grade no less than C20, Stamped
concrete, the curing period of the counter-weight must not be less than 15 days after
pouring.

2. Weld the joint of part 1 and part 3,steel pipe and part 2,part2 and part 4, part 3 and
part 4,part 4 and part 5,firmly together.
3. First,connect the reinforcing fabric with spot welding at the contact point,and put
it into the frame(part6,7,8).Then weld the angle steel frame firmly at the connect
point. Last,connect the reinforcingfabric and the frame with welding.
4. It is necessary to keep the dimensions 300x1220mm and to keep the same level of
the concrete surface as the frame when pouring.
5. Weld the part 9 and the part 10 firmly to the frame in order to fixing the part
1 and steel pipe.Weld part 10 to part 11 firmly.
6. The concrete strength is over c20.The allowable weight variation is 2%.
7. The weight should be printed at the two side of the top of the counter-weight;
8. All parts of the drawing are provided by user.

4 Foundation drawings
4.1 The foundation drawing for the outrigger crane
Foundation drawing for the outrigger crane TC6520-10E is shown as Fig 4.1-1.Its
technical requirement are as follows.
(1) Excavate a trench to hard formation until the ground bearing pressure accords
with the value in the following table, and make the bottom level. And then backfill and
tamp 100mm gravel stratum. After making formwork or laying bricks for the side walls,
pour concrete into pre-made reinforced rod net. The concrete block surface should be
100mm higher than neighbouring ground for the drainage of storm water, then removal the
formwork and backfill the neighbouring ground with gravels.
(2) The depth of the concrete cover of the main reinforcement is 40mm. Fix the
embedded anchors on the locating reinforcement bar and make sure that the verticality
of the embedded anchors centrelines and horizontal plane is less than 1.5/1000. Concrete
filling rate around the embedded anchors must be over 95%.
(3) The concrete strength grade shall be no less than C35. The curing duration of
concrete is more than 15 days.
(4) If it is difficult to pass through the anchor, the main reinforcing rod can be turned
aside, but must not be reduced or cut off.
(5) NO.6 which must driven 1.5m into the ground. Not connected with the steel
reinforcement of the building foundations.
(6) The NO.10 is insulated copper cable with at least 16mm.
(7) The Foundation is used for TC6520-10E tower crane whose independent height is
65m。The base load is showed in the instruction book.

7 Preparing for the outrigger crane
7.1 Permissible distance between the outrigger crane and the building For the adjustment of the accrete-frame,the distance between outrigger crane and the building should be
reference to paragraph 4.1.
7.2 Install Embeded Support Pillars
Two method for the install of Embeded Support Pillars: use the allocation crib or the base section. Allocation crib is recommend . 7.2.1 Use the allocation crib
For the easy to construct, when the bar is baled to a given degree,4 Support Pillars should be assemblage to the allocation crib 、the allocation crib to the section with 16φ65×164/203 pin、8 φ65×164/203 pin and 8 4×32 cotter pin. Put the Embeded Support Pillars 、allocation crib and the section which are installed into the bar-mat reinforcement. see Fig7.2-1.
Fig 7.2-1 Set drawing of Support Pillars and allocation crib
(1) The allocation crib is apolegamic ,and it is suggested;elsereference paragraph 7.2.2 to install Support Pillars. (2) The number of bar around the Support Pillars could not be reduced. (3) When the Main reinforcement is hard to pass the Support Pillars, it is permited that the Main reinforcement can dodge.

1) If allocation crib is purchased, we should install the Embeded Support Pillars as
paragraph7.2.1。
(2) In order to that the building won’t influence the Dismantling, it is necessary to
posit the step to the proper direction.
(3)The number of bar around the Support Pillars could not be reduced.

7.3 Cast concrete
Gently hoist the whole piece of anchors assembled with the base section as the fig 4.1-1a so that it is in a
vertical position before placing concrete.
(1)The concrete strength grade must not be lower than C35。
(2)Before casting concrete, Hang plumb lines along the center of base section to calibrate the
verticality of the center-line.
(3)Make sure horizontal plane is less than1.5/1000 and the flatness is less than 2mm.
(4)Concrete filling rate around the embedded anchors must be over 95%.
