SAFETY DEVICE
The hoist is equipped with various guards and devices designed to prevent accidents and to ensure the
product complies with various safety standards.
3.4.1 Primary Safety Component
The guards and devices listed below must not be removed by the user. Before operation the user should
ensure all guards and devices are present, correctly fitted and have correct setting.
Removal of these guards and safety devices should only be allowed during maintenance by competent and
authorised persons and in controlled conditions.
Chain guide plate
EXE Rise chain hoists are fitted with a special plastic chain guide plate that provides various safety
functions.
-
Prevents accidental contact with the internal moving parts.
-
Prevents accidental contact with the internal parts that could reach high temperatures.
-
Prevents wear between the chain and internal chain guide.
-
Prevents jamming of the chain.
-
Helps to reduce the chance of twisted chain entering the hoist.
These chain guides are a consumable item and should be replaced if they become worn.
Badly worn plates can be a sign of misuse. Eg. Side loading of the chain.
Hooks
The hooks are equipped with a sprung safety latch that prevents accidental release of loads when applied
correctly to the hook.
If this spring latch does not engage against the point of the hook correctly, or can fall through the opening of
the hook, the hook has overloaded and shall be replaced.
An unloaded hook attached to a lifting point can disengage itself when put under tension.
Therefore the hook shall be held under tension manually until loaded
Slip Clutch
The Slip clutch is designed and set up to act in the case of excessive load and therefore only shall be
considered as an emergency overload device. If overloaded, it starts to slip and the hoist will not lift.
The slip clutch shall never be used as a lifting height limiter.
If the clutch is subject to prolonged slipping it can overheat and become damaged. The clutch should not be
allowed to slip continuously for several seconds.
Considering the above statements, these hoists should not be used in an application where a suspended
load can be increased by adding additional weight. For example food lifts etc.
