Chapter 5 Assembly and Dismantling
5.1 Safety-technical notes
5.1.1 Notes on assembly
a) Make sure that the crane complies with operating requirements. Then check the positions
of A-frame, anchoring rod, FA-frame and assembly sequence of boom intermediate
sections one by one according to combination mode of boom.
b) Reeve the hoisting rope between the rope pulleys on the boom head and hook block in
accordance with the corresponding hoisting rope reevings.
c) Extend the crawler carrier to the required position, and assemble counterweight according
to relevant requirements.
d) Safe assembly platform must be used during crane assembly. Otherwise, there is a risk of
falling down.
e) Remove obstacles away from the ground on the site before assembling and dismantling.
In addition, the ground on the site should be cordoned off to prevent access by
unauthorized person.
f) Choose a flat ground to erect the boom.
g) Main boom length must be complied with load capacity chart under crane operation with
fixed jib. Reeve hoisting rope strictly in accordance with the reeving plans.
h) Each dismantled parts should not only satisfy the requirement of load-bearing capacity
under operating conditions, but also meet the art technology requirement of self-assembly
& dismantling operation.
i) Lattice components which are not in contact with the ground during assembly &
disassembly must be supported by appropriate and stable objects.
j) Make sure that no one stands beneath the lattice boom when the lattice boom is pinned or
unpinned.
5.1.2 Checking safety measures
a) Clearly define the duty and area of responsibility of all personnel concerned.
b) Check whether the crane is adjusted to be horizontal.
c) Check whether there is sufficient safety clearance to slopes and trenches.
d) For lines rated 50 kV. or below, minimum clearance between the lines and any part of the
crane (including the load) shall be at least 10 feet; Except where electrical distribution and
transmission lines have been de-energized and visibly grounded at the job site.
For lines rated over 50 kV., minimum clearance between the lines and any part of the
crane (including the load) shall be 10 feet plus 0.4 inch for each 1 kV. Over 50 kV., or twice
the length of the line insulator, but never less than 10 feet.
