2. Designed purpose of use
The AVANT Leguan 50 Access platform is an attachment suitable for use with AVANT multi purpose loaders
shown in Table 1. The LEGUAN 50 is a mobile lifting platform for indoor and outdoor use and it is designed
and manufactured to be an attachment for AVANT compact loaders. The Leguan 50 is an access platform
intended to lift persons and their equipment needed in work. The use of the Leguan 50 as a lifting crane for
lifting objects is prohibited.
The access platform can be used only with Avant multi purpose loaders. Use with other
type or brand of machinery is prohibited. The access platform can be used with 400-700
series Avant loaders, when rear support legs have been installed.
During lifting operation, the access platform is supported by its own outriggers and the extra outriggers fitted
to the rear of the loader. The platform is controlled from the lifting platform, and the AVANT loader works as
the hydraulic energy supply for the platform. The stability of the platform is based on the rigid fixing of the
attachment to the loader, and because of this, the instructions concerning installation procedures must be
followed carefully. With the emergency lowering valves the platform may be lowered in case the loader engine
shuts off.
The LEGUAN 50 has been designed and built according to international safety and access platform
standards. Regular maintenance tasks can be performed by the operator. More demanding maintenance and
repairing work must be left to qualified professionals. Appropriate protective equipment and original spare
parts must be used for the maintenance.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your
AVANT retailer if you have additional questions about the operation or maintenance of the equipment, or if
you require spare parts or maintenance services.
