CRANE TOWERS AND ANCHORAGES (1,20m)

1. CRANE TOWERS

1. 1. FREE STANDING CRANES

- The mast compositions on pages 29A--0520--.. are given for free standing heights IN SERVICE andOUT OF SERVICE and for the static and rail--mounted versions indicated in the data sheet.

- There are several types of mast sections of various lengths.

- The assembling order is that given in paragraph (29A--0520 --...) for reasons of strength. These docu-ments deal with the optimum composition of the crane tower which is not allowed to be lower. But itis possible to fit stronger sections (*).

(*) Please consult us

1. 1. 1. REDUCING THE FREE STANDING HEIGHT DUE TO THE TELESCOPICCAGE.

If, for reasons of later increase in height, the telescopic cage is to be left at the top of the masts, it is abso-lutely necessary to reduce the free standing height IN SERVICE and OUT OF SERVICE by removingX mast sections (**).

(**) COMPULSORILY consult us

IMPORTANT:The very high cranes are subjected to a downgrading of the load, seechapter Special characteristics.

2. VERY HIGH CRANES

Beyond the free standing height of rail--mounted or static crane, the crane must be connected either tothe ground by anchorage by guy ropes or to the building by rigid anchorages.

For each utilization of anchorages on cranes with chassis, please consult us.

2. 1. WITH RIGID ANCHORAGES TO THE BUILDING

- The heights indicated in the tables of pages 29A--0530--... are the hook heights and the anchorageheights on fixing angles taken with respect to the joint face of the fixing angles.

VERY IMPORTANT:The anchorage heights and the distances between the frames are

minimum values which must be strictly observed. Each valuelowerthan the indicated one results in a smaller number of sec--tionsabove the anchorage (therefore a downgrading of the hook height).Please consult us.

The mast composition is given for the optimum utilization of theframe.

- The mast compositions and the loads applied on the frames are given on pages 29A--0530--...

- The determination and the execution of the beams connecting the anchorage frame to the buildingare on the users responsibility. They must be able to take up the loads and reactions given in thetables on pages 29A--0530--...

2. 2. WITH ANCHORAGE BY GUY ROPES

- Please consult us.

3. A SET OF MAST SECTIONS

3. 1. SECTIONS OF 10,5 M LENGTH- SR24B Cross section 1,20 x 1,20 m -- length 10,5 m -- Upright L 150x15 -- Monoblock tower

section -- witht lugs -- allows starting telescoping with mast sections of 3 m length.-- lower-fish joint D50 -- upper fish joint D40.

3. 2. SECTIONS OF 3 M LENGTH

- S24A1 Cross section 1,20 x 1,20 m -- length 3 m -- Upright L 150x15 -- Monoblock mast section-- with lugs -- can be telescoped

- S24A2 Cross section 1,20 x 1,20 m -- length 3 m -- Upright L 150x15 -- Monoblock mast section-- with lugs -- with resting platform -- can be telescoped

3. 3. TELESCOPING MAST

- Cross section 1,20 x 1,20 m -- length 1,50 m -- Monoblock mast section -- with fixing gus-setsfor the telescopiccage. Always placed under the fixed towerhead, it ensures the con-nection with the other crane tower sections.
