1Introduction and features
Congratulations!
With the new Hercules LITE SAL you have purchased a handy modular–designed sack truck with an
unladen weight of only 16kg.
Once you fit the snap-on battery, this simple sack truck becomes a versatile all-rounder: a normal sack
truck for general use on level ground and a powered stair climber for use on steps and stairs.
Additional features, such as the wide pneumatic tyres*, make this equal to any conventional hand truck for
use outdoors and for professional deliveries but with the added bonus of going up steps and stairs as well.
With the SAL Series climbing stairs has been reduced to the essential: The Hercules LITE pulls itself up
onto the step above and lifts to only the necessary step height.
During descend, the motor acts like an electric brake and the load is brought down without “bumping”. It is
also ideal for winding staircases and across tight landings.
The Hercules LITE SAL has a mechanical clutch which will prevent damage if the unit is used to descend
the stairs with the controls in the ascend position.
The unit also features electronic overload protection preventing ascend with too heavy a load.
The Hercules LITE SAL has two ascending speed settings (slow and fast –with a speed of up to 48 stairs
per minute in the case of the SAL 110 models), plus a wide variety of model options, lifting capacities and
additional accessories.
In other words, a professional for professionals!
1.1 General safety instructions
▪Always ensure that there is no member of the public, or anyone who is not directly associated with
operating or assisting with the operation of the stairclimber beneath the load.
▪Always secure the load with the appropriate straps or other accessories
▪Always wear rubber soled shoes. Some stairs can be extremely slippery
▪It is recommended, but not mandatory, to wear shoes with steel caps
▪Never reach into the lifting mechanism with your hands if the battery is inserted
▪At first practice using Hercules LITE SAL either unladen or with a light load of 20 –30 kgs
▪For transportation remove battery to lighten the unit and to prevent accidental operation in transit
* puncture proof version also available
