M880 KRON - OPTIONALS

PWM APT400 ACTUATORS

APT400 electro-hydraulic actuators are compatible with KRON, ZEUS2 and THOR2 radio remote controls and allow you to operate most hydraulic cranes equipped exclusively with manual commands.
Since the system does not have to be welded to the push rods, the original machine configuration will remain unaltered.
The electro-hydraulic circuit of the APT400 system was separated from the crane system thanks to a dedicated electro-hydraulic control unit. This helps avoid potential malfunctions that might arise if the system shared the hydraulic circuit of the crane, which is typically already worn due to heavy work conditions.
The control unit is activated only when operations are performed via the radio remote control (“on demand” activation), thereby avoiding energy waste and reducing both wear and operating temperature.
APT 400 actuators are calibrated once the installation is completed, using the radio remote control transmitting unit.

STROKE EXTENSION KIT

The standard actuator stroke is of ±13 mm from the centre and is suitable for most hydraulic distributors available on the market.
To accommodate special needs, the piston stroke may be extended up to ±20 mm with a specific kit.

ADAPTER KIT

Thanks to a specific flange kit, APT400 actuators may be connected directly to Walvoil SD6-SD8, Galtech and Parker manual proportional distributors.

This configuration requires removing the push rods.

Multi-receiver and / or Multi-transmitter configuration 

IMET makes available to its users, special radio remote control configurations that allow, by a simple selection command, to macht one receiver with more than one transmitter or alternatively, several transmitters to one or more receivers. This is particulary useful when operating industrial cranes.
a) The available configuration are Tandem, Take/Release and Master/Slave, aimed at satisfying the most demanding operational requirements.
b) Selectable receivers: allow to select from a single transmitter up to 8 receivers or 8 combinations of more receivers.
