2. PRODUCT PRESENTATION
2.1 - Product range
Hoist : The tralift™ TE product line is composed of different models outlined (Fig. 3). The rated load range of 125 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, gear or electrical trolley (Fig 3 / 5 / 7 / 8).
Trolley : The trolley range is composed of 3 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 (3 single speed & 2 double speeds) and 2 different type of mounting (hook suspension or lug mounting).
The corso push trolley : exist (1 or 2 ton with either hook or lug mounting).
The corso gear trolley : exist (1 or 2 ton with either hook or lug mounting).
2.2 - Operating principle
Hoist : The tralift™ TE 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 chain bag. For the double falls version, one end of the chain is fitted to the
hoist body (fix point). The chain is going through the load hook going up to the sprocket wheel and the other end is fitted with
an end stop. The loose chain is stored in chain.
The hoist is activated by a low voltage pendant control with three buttons: Lifting lowering and emergency stop. The hoist body
includes a rigid suspension hook or rigid axle (for lug mounting) to fit the hoist onto a support structure. The bottom hook (load
hook) is equipped with ball bearing to help the load to get the right positioning during lifting movements. 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.
Electrical Trolley : A motor with a self braking worm gearbox operates two driving wheels via a pinion. A connecting bracket is supplied
as standard to connect the trolley electrical box to the main power feeding line leading trolley. Two drive limit switch
devices can be fitted as option.
