The Weighlog 2 is intended for use on skid-steer loaders, utility tractors with a
loader attachment, wheel loaders, backhoe loaders (loader side only), and
gas powered fork lifts.
It measures, displays and records the net weight lifted, normally based on
sensing the lift system hydraulic pressure. Pressure sensing is problematic on
certain types of equipment due to the design of the hydraulic system. In
these instances strain sensing technology may be used instead.
System Components
Load sensor : This is either a 250 bar rated pressure sensor fitted in the lift
ram hydraulic circuit, or in some instances it is a strain sensor mounted on
the top side of the lift arm (e.g. on certain telescopic loaders).
Reference Position/Direction sensor : The pressure/strain must be
measured with the mechanical linkage in the same position each time. The
reference position/direction sensor is mounted near the lift arm pivot. It
identifies when the lifting attachment is in the correct weighing position, and if
the load is being lifted or lowered. The sensors are triggered by a magnet
mounted on the side of the lift arm.
Remote Enter button: This is mounted next to the lift lever and is used to
record the bucket weight.
Head Unit and wiring: The head unit is supplied with a universal mounting
bracket assembly allowing it to be mounted in almost any configuration.
