injuries to you and damage to the trailer.
Operating a trailer requires a high level of expertise, as well as knowledge about the machine you are
using. It is important for you to train with regard to the trailer’s behaviour. Practice the movement
pattern and always work with smaller loads until you are completely familiar with operating the trailer.
BIGAB Hooklift is intended for use in agricultural, construction and community work for collection and
transportation of waste, scrap, agriculture and other goods.
Bigab Hooklift is not intended for use in transporting people or animals.
Take care to ensure that nobody is within the safety zone 20m.

trailer is being driven, moved with frame steering or when other
functions are activated between the trailer and towing vehicle, can
be potentially fatal. As the driver, you must always ensure that no
one is in the area around the machinery.
Risk of slipping
There is a risk of slipping as the surfaces of the trailer can be
slippery due to combination of oil/mud/rain on the surface. The
ground around the trailer can also become slippery, as the tires
can tear up the surface and expose mud and soil.
Hydraulic uid under pressure
Hot hydraulic uid at high pressure levels can occur in the
hydraulic system. Take care when connecting, disconnecting and
replacing hoses.
Maximum load to coupling device
Ensure that you do not load in such a way that the load on the
towing eye exceeds the permitted values.
NB! Check your permitted towing eye vertical load value from
technical data and marked for the towing eye. The load is largely
determined by the way the weight is distributed on the container
bridge, and it is the user´s responsibility to ensure that this is not
exceeded.
