2�1� Product range
Hoist:
The volt trac™ product line is composed of
different models (Fig. 3). The rated load range of
250 kg to 2 ton is available in one or two lifting
speeds. On request the hoist may be delivered
with different lifting heights or pendant control
cable lengths. The hoist can be fitted with push or
electrical trolley (Fig 6, 8).
Trolley:
The trolley range is composed of different models
The corso TE range exist in two different models
(1ton or 2 ton according to the following table
(Fig. 5) with various travelling speed possibilities
(1 single speed & 2 double speeds) and 2
different type of mounting (hook suspension or
lug mounting).
corso push trolleys with capacity - 1t, 2t or 3t either
with hook or lug suspension
The minimum turning radius of the 1t, 2t and 3t trolleys
are shown in Figure 20.
2�2� Operating principle
Hoist:
The volt trac™ is an electric chain hoist powered
by a motor driving through a gear box. The gear
box turns a load wheel which in turn moves the
chain. For the single fall version, one end of the
chain is fitted with the load hook and the other
end is fitted with end stop. The loose chain is
stored in a chain bag. For the double falls version,
one end of the chain is fitted to the hoist body
(fixed point). The chain goes through the load
hook block over a sheave and then up to the load
sprocket wheel and the other end is fitted with an
end stop. The loose chain is stored in chain bag.
The hoist is activated by a low voltage pendant
control with three buttons: Lifting lowering and
emergency stop. The body of the hoist includes
a rigid suspension hook or suspension eye or lug
(for direct mounting on a trolley) to place the hoist
on a supporting structure. The bottom hook (load
hook) is equipped with ball bearing which helps
the positioning of the load. The load is connected
to the load hook directly or through an accessory
such as a sling. The hoist is equipped with an
electromagnetic disc brake connected to the
motor shaft. The brake holds the suspended load
when the pendant control is not activated or in
case of power failure. Safety devices ensure that
the hoist conforms to safety regulations.
