Crown TR 4500 Series of tuggers
Crown Equipment Corp.'s new TR 4500 Series of tuggers allows operators to tow a rolling load capacity of 10,000 pounds.
Crown designed the drive unit of its TR 4500 Series to endure the constant jerks, jolts, and other demands placed on tuggers operating in high-throughput warehousing environments, according to the company. Crown says that the Series' AC drive motor is the largest in the industry and provides high torque and great draw-bar pull. The Series also uses this high torque to power its e-GEN braking system, which provides frictionless braking.
To create a durable frame, Crown used a combination of heavy-gauge steel and structural enhancements at the greatest points of stress. The equipment also has steel power-unit doors to protect its internal components. The Crown TR 4500 Series also features a13-inch drive tire. According to Crown, this feature extends the tuggers' run time compared to other brands' 10-inch tires.
The Crown TR 4500 Series also offers ergonomic features. Its electronic power steering system eliminates awkward body movements that can contribute to operator fatigue and stress, says the company. The operator compartment of the Crown TR 4500 Series includes a padded wrap-around backrest that contours to the operator and an operator-sensing floorboard.
