3.3 PNEUMATIC CHAIN HOIST WITH TROLLEY
The trolleys are supplied pre-assembled for beam widths A or
B (see table 1). This is shown on the nameplate. Before instal-
lation ensure that the trolley width is correct for the intended
carrying beam.

Attaching the load
The load must always be seated in the saddle of the hook.
Never attach the load to the tip of the load hook. This
also applies to the suspension hook (fig. 10).
Inspecting the traverse (for trolleys)
Inspect the traverse for correct assembly and visually
check for external defects, deformations, superficial
cracks, wear or signs of corrosion. In particular check
that the roll pins in the centre traverse have bee fitted
correctly (fig. 12)
Check adjustment of trolley width
On chain hoists without suspension hook (CPA-VTP/G/
E) check that the clearance between the trolley wheel
flange and the beam outer edge is equal on both sides
and within the tolerances given (see page 6). Enlarging
the clearances, e.g. to enable the trolley to negotiate
tighter curves, is forbidden.

3 ASSEMBLY
3.1 Inspection before assembly
Check for transport damage
Check for completeness
Check that the lifting capacity of hoist and load hook
match
3.2 Pneumatic chain hoist with hook suspension
(Standard design)
The standard Yale pneumatic chain hoist is fitted with a
suspension hook.
The suspension hook is connected to the hoist with two
suspension pins. Independent of how the hoist is reeved
it must always hang vertically under the suspension hook.
In single-fall operation the suspension hook is to be in-
stalled centred on the marking 1/1, for dual-fall opera-
tion centred on the marking 2/1 (see fig. 11).
Attention
: Secure the two suspension pins with the lock-
ing plate after assembly.
The selection and calculation of a suitable suspension
point is the responsibility of the user and must be adequate to
support the hoist while it is being operated at its maximal lift-
ing capacity.
