Mack Trucks has enhanced its LR refuse truck, the company says, with an emphasis on improved safety and driver productivity features for its customers. Mack made the announcement at Canadian Waste and Recycling Expo, Oct. 24-25 at the Enercare Center, Toronto.
Among the upgrades, Mack engineers have added passenger side sliding glass window for superior visibility, and a Sears C2 PLUS air suspension seat for enhanced driver comfort. Both specs are now standard on the LR model and available for order. Mack also announced that an exterior stainless steel sun visor and 315 series tire coverage for the Hendrickson HAULMAAX suspension are now available for order.
“Mack designs every product and service with our customers in mind,” said Curtis Dorwart, refuse product manager for Mack Trucks. “Refuse customers have a unique set of challenges facing them on the job, so Mack took their input and developed features that would help improve safety, comfort and productivity.”
Dorwart said the new sliding glass window improves ventilation and allows easy access to the passenger side mirror during right-hand stand-up or sit-down operation. The exterior stainless steel sun visor, available as an option, improves heat deflection and reduces glare, while standing up to harsh refuse operating conditions.
The Sears Seating C2 Plus air suspension seat offers an even more comfortable ride, Dorwart said, while a Sears Seating multi-position right-hand seat is standard for customers who spec right-hand operation LR models. The multi-position seat, engineered exclusively for the Mack LR, enables more adjustability for right-hand operators whether standing or sitting, as both the seat back and seat base are adjustable.
Also now available for order on Mack LR and TerraPro models is TMC RP170A, a set of chassis-to-body electrical interface guidelines for refuse trucks. The electrical interface was developed through industry collaboration by the American Trucking Associations’ Technology & Maintenance Council (TMC), and allows for easier upfit, standardization and ease of troubleshooting and maintenance.
Mack’s 11L MP7 diesel engine is standard in the LR model, delivering up to 355 hp and 1,260 lb.-ft. of torque. The LR is equipped with an Allison RDS 5-speed or 6-speed automatic transmission.
