050-350-061-225 PAT HIRSCHMANN CONSOLE, DS350, VERT 24V L-BAEG, 4 DECADE SW. LATTICE
This console is often found in older Link Belt lattice cranes including the HC238 or HC248 series. Though this console is still available the majority of our customers find it more economical to purchase a complete new system. More information can be found here:

The PAT DS 350 Rated Capacity Limiter (RCL) has been designed to provide the crane operator with essential information required to operate the machine within its designed parameters.
The PAT DS 350 Rated Capacity Limiter (RCL) monitors various crane functions and provides the operator with a continuous reading of the crane’s rated capacity. The readings continuously change as the crane moves through the motions needed to make the lift. If a non- permitted condition is approached, the RCL is designed to warn the operator by sounding an audible alarm and illuminating a warning light.
During crane operation, The RCL provides the operator with information such as: the selected operating mode, main boom length, main boom angle, jib length, jib angle, and the total load being lifted by the crane. The total load is defined as all weight at the end of the hoist line, which includes hook block, load, rigging, etc..
This manual describes the function, operation, and maintenance of the PAT DS 350 Rated Capacity Limiter (RCL) System for Link-Belt Lattice-Boom Cranes.
This system assists the crane operator in promoting safe and efficient operation by monitoring crane loads and by warning the operator of approaching overload conditions
PAT DS350 Link Belt Lattice Computer Layout
PAT DS350 Link Belt Lattice Crane Computer System Description
The PAT DS 350 RCI computer system installed on many Link Belt lattice cranes consists of a central microprocessor unit, operator’s console, and component sensors for angle, load, and anti-two block (A2B) condition. The system uses angle sensors to measure boom and jib angle, if applicable. The hoist line tensiometers (lineriders) measure the load. And the A2B switch senses an approaching a two block condition.
The system operates on the principle of comparing real to reference data. The real data is supplied to the central unit by sensors and the operator’s input settings, such as: operating code, hoist selection switch, and reeving switch. The reference data (i.e. crane capacity charts, geometry) is supplied by the crane manufacture and stored in memory chips in the central processor unit. The microprocessor evaluates the real data (sensors and operator input) to determine an operating mode. The operating mode determines the reference data required to calculate permitted operating limits. When limits are exceeded, warning signals are generated and viewed at the operator’s console.
