3 Description
3.1 Overview
The GANTERUD L3 is a radio-controlled lifting
yoke that is used for precision adjustment of
heavy objects, such as structural elements,
beams, roof trusses, etc., when lifting with a crane
or other lifting equipment.
The lifting table applies during normal usage. In
the event of any uncertainty, scales/load cells
must be used to measure the load at each end of
the chain.
A. Remote control.
B. Motor switch. Breaks the power supply to the motor. Must be switched o when the
batteries are being charged.
C. Battery charger.
D. Batteries.
E. Battery indicator. Indicates battery status. 25 - 100%.
F. Cable for battery charger. Connected to 230V AC 50 Hz for charging batteries.
The lifting yoke is powered by a built-in electrical
motor equipped with a rechargeable battery, and
can be used with most types of cranes and lifting
devices.
3.2 Lifting capacity
Exceeding the maximum chain angle or the
maximum lifting capacity will damage the
equipment.

3.2.2 Levelling expressed as height dierence
The table below shows the height dierence
that various levelling angles equate to for lifting
objects of dierent lengths. All lengths are
specied in millimetres (mm).
If necessary, the height dierence can be
calculated by multiplying the length of the lifting
object by the sine:
h = L x Sin(a)
Height dierence, h [mm]

3.3 Remote control.
The lifting yoke is equipped with radio control and is controlled by the supplied remote
control.
The remote control is calibrated for the lifting yoke, using a specic radio frequency.
This means that several lifting yokes can be used with their own remote controls on the
same work site, without disrupting each other.
If several remote controls are used on the same work site, and for some reason are
using the same radio frequency, there is a risk of them disrupting each other. In this
case, it is necessary to change the radio frequency of the aected remote controls and
receivers.
Changing the radio frequency may only be performed by authorised personnel.
3.4 Intended use
Ganterud L3: The lifting yoke is intended for lifting objects with a maximum weight
of 3 tonnes, as well as for levelling where the maximum imbalance between the
attachments is 500 kg.
The lifting yoke is intended for lifting with a maximum chain angle of 60°.
The lifting yoke can be used both indoors and outdoors, within a temperature range of
-20°C to +40°C.
3.5 Disposal
Disposal must take place in accordance with local rules and regulations.
