One of the best ways to handle moving aggregate materials and debris from demolition is with an Articulated Dump Truck (ADT), and the Bell series of ADT models are among the finest on the market. The Bell B50e ADT is one of the most powerful models they offer, with incredible muscle behind it: a true 50-ton truck that can meet all but the most demanding of needs. With an amazing Mercedes-Benz diesel engine and a 7-speed transmission, the B50e is one of the most powerful trucks available from Bell and a great choice in any construction fleet.

The Bell E Series of Trucks

The Bell E Series of trucks are some of the finest ADT models on the market, giving you a tremendous amount of power and fantastic features to help you get your job done. Every truck in the E Series uses a Mercedes-Benz engine with an Allison transmission that makes them easy to operate while still delivering all the power you need. The Bell B50e ADT and other E Series trucks all feature a six-wheel-drive system with an exhaust brake, which helps with descent control on steep inclines and other rough conditions that often arise on a job site.

All of these trucks include an onboard weighing system that provides the truck operator with weight information in real-time, which makes it easier to avoid overloading and ensures safe use. Along with this, you also get terrific safety features on the Bell E Series of trucks, including a rear suspension designed to keep the rear wheels on the ground even during heavy use, along with a safe tip function that prevents the rear bin from lifting if the rear chassis exceeds a pre-set roll value. You can set control limits on these trucks to make sure they are used safely at your job site, and there are automatic parking brakes and hill assist to make them even safer.

Perhaps the most remarkable feature of the Bell E Series is the [email protected] system that allows you to easily view what is going on with your trucks at all times. This is a computer system that monitors and tracks data from your trucks, then sends that information to you, which you can read and view from a phone, tablet, or computer. This information includes data about load weights, operation hours, and can even alert you to abuse or improper conduct from your truck operator. All of this allows you to keep your eyes on your machinery even if you cannot be at a job site all the time, so you always stay informed.

he Bell B50e ADT

Within the Bell E Series of trucks, the Bell B50e ADT is one of the most powerful models available, with only the B60e offering greater performance. This is a 50-ton truck that can handle pretty much anything you throw at it at your job site, so it is a great choice for getting a lot of work done. It is powered by a 15.6L Mercedes-Benz diesel engine that delivers up to 577 hp and more than 2,000 lb-ft of torque. This comes paired with a 7-speed transmission that offers better performance than previous Bell ADT models and has improved the ratio step between gears.

Performance is the name of the game with the Bell B50e ADT, giving you the muscle you need to handle just about any task. This includes a 28 cu.yd. struck capacity for the bin, with an SAE 2:1 capacity of 36 cu.yd. and an SAE 1:1 capacity of 43 cu.yd. It has an SAE 2:1 capacity with the tailgate of 38 cu.yd. and it is rated for more than 100,000 lbs. of payload, with newly designed tires capable of handling that much weight safely. This is a truly remarkable dump truck that makes moving tremendous amounts of materials or debris easier than ever before.
