Model D4070/D4077 Electric Hoist
-5-
The Model D4070/D4077 electric hoist
comes pre-assembled and only needs to
be mounted to prepare for operation.
There are many mounting options for
your hoist. It may be mounted on a metal
tubing or on a rotating pillar (Figure 3).
Above all, choose a mounting option that
is safe and will withstand the maximum
rated load of the hoist.
Mounting
Lifting Equipment
When attaching lifting equipment to
the electric hoist:
• DO NOT attach multiple chains or
harnesses directly to the hook. Only
one point of contact should be used
on the hook and shackle to lessen
the chance of the load falling and to
allow proper load alignment. Use a
multiple chain sling similar to the one
shown in Figure 5.

Also, make sure that the selected
location is in a well lighted environment,
the control switch will be within reach,
and that the hoist will not be exposed to
rain or moisture.
To mount your electric hoist:
1. Place the two mounting brackets over
a suitable fixture that will withstand
the maximum load capacities and any
possible overloading that may occur.
2. Have an assistant hold the hoist
in place, and thread the hex
bolts, external tooth washers, and
flat washers through each of the
mounting brackets and into the top of
the electric hoist (see Figure 4).
Note: We strongly recommend using
medium strength thread locking
compound on the hex bolts when
securing the hoist.
• DO NOT attach oversized items
or harnesses directly to the hoist.
Oversized lifting equipment creates
multiple points of contact and will
not fit properly on the hoist hook,
resulting in uneven and dangerous
lifting loads.
3. Firmly tighten the hex bolts, and
check to make sure the hoist does not
swing or move after mounting.
