chain will continue to travel through the hoist in the chosen direction until it reaches a mechanical stop on the
chain, or until the electrical limit switch reaches its pre-set end point. Once the limit switch is activated the
hoist can only be run by reversing the direction of travel.
Any control unit used to power EXE-Rise LVC hoists must provide an "un-inverted" three phase power
supply. An incorrect sequence of phases make the hoist run in a different direction as the limit switch. This
will result in damage of the limit switches and potential over run of the chain.
Electric chain hoists are offered in a variety of designs and feature options; as well as with different safety
devices. This means that the choice of chain hoist is extremely important. Consideration must be given to
risks arising from the nature of the intended operational use and the specific operating conditions.
The selection must be based on the hazards arising from the type of use, taking into account the specific
conditions of use whilst abiding to the local laws in the country of use. We strongly advise that the
user/operator carries out a risk assessment on which the choice of your hoist shall be based.
3.3 COMPONENTS DESCRIPTION
Every single component of the EXE-Rise hoist body is manufactured in Italy. The high grade Lifting chain is
coming from Germany and complies with the strictest EN and DIN standards relating to lifting in the
entertainment industry. The EXE-Rise clutch system is located outside the load path. The DC brakes give a
real instant response to electrical impulses thanks to a unique component specifically created for us. The 5-
pocket load wheel, helical gears with dynamic lubrication and the precise aluminum chain guide make
the EXE-Rise series one of the quietest on the market.
