Project Overview
This customer provides commercial and residential contracting services along the great lakes. They had a Shuttlelift utilized for smaller projects and for work in their yard. They wanted a compact option for the smaller crane. We were able to work with them on a smaller system using a mini cable reel and pressure transducers. The small unobtrusive system will give the years of safe use of this smaller crane.

The i4300 is a computerized crane monitoring system, designed as an operator aid. It comprises sensors fitted to the crane and a display located in the cabin of the crane. This version measures the boom cylinder pressure or the tension in the hoist rope, the boom angle and length, and it indicates safe or critical conditions, while performing an authorized lift of loads.
All the sensors are linked through a single CAN Bus (Controlled Area Network). The pressure sensors or a dynamometer provide electrical signals that are proportional to ther load lifted. An inclinometer provides a signal that is proportional to the boom angle and a reeling drum provides a signal that is proportional to the boom extension. The radius and the load are calculated from these signals with the dimensional crane data preprogrammed in the i4300 system.
During operation the load lifted by the crane is calculated from the measured boom cylinder pressure and is automatically compared with corresponding data related to the maximum permissible crane loading.
The actual load is expressed as a percentage of the permitted load (% SWL). If this percentage exceeds a preset value, alarms and safety functions are activated. The values of the hook load, the permissible load, the main boom angle and the radius are displayed in a digital form on a graphic liquid crystal display (LCD).
The required crane duty charts are stored in a non-volatile memory and can only be modified with the approval of the crane manufacturer. The calculated crane parameters and calibration data are stored in an additional non-volatile memory. The calibration of the system is performed only with the use of known loads, boom angles, and other pre-determined data.

Versatile Power in Compact Form
Versatile Power in Compact Form
Carry deck cranes such as the Broderson, Shuttlelift, or Grove Yard Boy offer unmatched versatility and maneuverability, making them a go-to choice for industrial plants, construction sites, and maintenance operations. Their compact design allows them to navigate tight spaces and confined job sites where larger cranes can’t operate effectively. Equipped with a rotating boom and a flat deck for material transport, these cranes can lift, carry, and place loads with incredible efficiency—all from a single position. This combination of mobility and lifting power makes carry deck cranes indispensable for projects that demand flexibility, speed, and precision in limited work areas.
Efficiency That Drives Productivity
Efficiency That Drives Productivity
Beyond their compact footprint, carry deck cranes deliver significant operational advantages that improve productivity and reduce costs. They are quick to set up, easy to operate, and capable of handling multiple tasks—such as loading materials, transporting equipment, and positioning components—without the need for additional machinery. Their 360-degree boom rotation provides exceptional reach, while their low-profile design ensures stability and visibility for the operator. Whether used in refineries, factories, or construction zones, carry deck cranes maximize uptime and deliver reliable performance day after day, making them one of the most efficient and cost-effective lifting solutions in the industry.

Aftermarket Crane Safety Products
BTS has always been on the forefront of advocating for crane safety through crane LMI or RCI computer systems. This is one of the earliest industry articles highlighting the need for aftermarket crane computer systems for those with aging or non existent systems.
Water & Electronics Dont Mix
Water & Electronics Dont Mix
Preventing unnecessary crane down time due to water intrusion is one of the main goals of the BTS service team. Undoubtedly water in the LMI cables or system boxes themselves has been the number one cause of failures or erratic crane computer behavior.
Wiring & Insulation Issues
Wiring & Insulation Issues
Addressing two key issues of insulation and wire gauge on live wires in the crane computer LMI system. Especially prone to neglect are wires and cables that run between the sensors and the main console / central unit computer. Over years of weather exposure there can be significant deterioration that results in incorrect sensor readings and unreliable error code messages
About LMI Load Moment Indicators / Crane Computers
About LMI Load Moment Indicators / Crane Computers
A Load Moment Indicator LMI crane computer system operates on the principle of reference/real comparison. The real value, resulting from the pressure measurement and geometric sensors, is compared with the reference data stored in the central processor memory and is evaluated in he microprocessor. An analog indication of % capacity is displayed via an boom truck crane operator’s console. When limits are reached, an overload warning signal is generated. At the same time, the crane movements that increase load moment such as hoist down, telescope out, and boom down will be locked out. The fixed data regarding the crane, such as dimensional data, capacity charts, boom weights, and centers of gravity are stored in memory chips in the central processor unit. This data is the reference information used to calculate the operating conditions. Boom length and boom angle are registered by the length/angle sensor, located inside the cable reel, mounted on the boom. The boom length is measured by the cable reel cable, which also serves as an electrical conductor for the anti-two- block switch. The crane load is measured by pressure transducers attached to the piston and rod side of the lift cylinder. Controls on the operator’s console allow the operator to select the operating mode (main boom, jib, etc.) as well as the parts of the line currently in use. The system will then limit operation to the capacities on the selected load chart, or the maximum permissible line pull in that configuration. After the engine is started and the PTO is engaged, the LMI powers up and conducts an automatic test of the complete system. After two successful system tests without errors, the system is ready for operation. In case of a system error, both the overload and anti-two-block lights on the central unit will illuminate. The interactive user guidance considerably simplifies the input of operating modes as well as the setting of geometry limit values
The LMI crane computer is an operational aid that warns a boom truck operator of approaching overload conditions and over hoist conditions that could cause damage to equipment and personnel. The device is not, and shall not, be a substitute for good operator judgment, experience and use of accepted safe crane operating procedures. The responsibility for the safe crane operation shall remain with the crane operator who shall ensure that all warnings and instructions supplied are fully understood and observed. Prior to operating the crane, the operator must carefully and thoroughly read and understand the information in this manual to ensure that he knows the operation and limitations of indicator and crane. Proper functioning depends upon proper daily inspection and observance of the operating instructions set forth in the operators manual
