Work safely and efficiently with LENNIX® Pro
Automation Solutions for Slewing Cranes

Applications

Sway movements of load are often provoked during operation of cranes. Swaying movements are also caused by external forces like wind or inclined hoist. These load sway movements may slow down the
handling operation or cause collisions.  

LENNIX® Pro is a controller that eliminates load swaying by itself. The controller ensures rapid and safe crane handling operation, relieves the crane operator from stress and reduces the risk of collisions.  

LENNIX® Pro is used in single-jib cranes and double jib level luffing cranes. He controls two – slewing gear and luffing gear.

LENNIX® Pro has been designed for manual and automatic control of cranes. The System may be adapted to geometric conditions of luffing gear. With the extra function „Tandem“ the system may be used for automatic tandem operation of slewing cranes.  

Function

The speed pre-set by crane operator in manual control is influenced through acceleration and deceleration operations so that resultant load swaying movements during travel and at stop are eliminated automatically. Consequently, rapid and safe positioning is possible.

The system in automatic operation uses the transmitted target position for calculation of the shortest way with the associated optimum speeds for all axes. Load swaying movement generated here is automatically eliminated in this case as well. The principle is comparable with due-time counter-steering actions taken by a well experienced crane operator.

LENNIX® Pro optional uses a high-resolution camera measuring system for exact position detection of the load handling attachment. One passive reflector suited for this application without voltage supply is fitted to one side of load handling attachment.

Manual operation

The crane operator can switch between control in polar coordinates (angular position and radius) and control in Cartesian coordinates (X,Y).

Cartesian control is especially useful when driving around straight obstacles or following a line.

Automatic positioning

With LENNIX® Pro for Slewing Cranes the crane can automatically reach its destination. In this way the load can arrive in the fastest and safest way possible while still maintaining anti-sway.

Tandem mode operation

Handling of cargo with two slewing cranes

Operation Modes

  • Automatic synchronisation of two mobile cranes for tandem mode operation
  • Intuitive control in Cartesian coordinates for a linear approach
  • Rotation of the load

Advantages

  • Relief of the strain for the crane operator
  • Direct control of both cranes from the master crane or by remote control from the ground by one trained crane operator
  • 100% utilization of the load capacity of both cranes instead of 80% load carrying capacity without joint control
