Question 1

What are the key specifications of these 2007 Mellot Stacking Conveyors?

Accepted Answer

These are 2007 Mellot Stacking Conveyors available in two sizes: two units with 24 inch belt width x 60 feet length, and two units with 30 inch belt width x 60 feet length. All four units feature electric power, radial movement capability, hydraulic low tail sections, integrated Beltway conveyor belt scales, and 5th wheel pin connections for portability. They are pit-portable units designed for flexible material handling in aggregate operations.

Question 2

What materials can these 2007 Mellot Stacking Conveyors handle?

Accepted Answer

2007 Mellot Stacking Conveyors are designed to handle aggregate materials including crushed stone, gravel, sand, recycled concrete, asphalt millings, and similar bulk materials. The 24 inch belt models typically handle lighter or finer materials, while the 30 inch belt versions can accommodate higher volumes and heavier aggregates. Capacity depends on material density, belt speed, and the angle of inclination.

Question 3

What is the typical capacity of these 2007 Mellot Stacking Conveyors?

Accepted Answer

While the listing does not specify exact tonnage, standard radial stackers of this size typically handle between 300 to 800 tons per hour depending on material type and belt speed. The 30 inch wide belt models generally provide higher capacity than the 24 inch models. Actual capacity will vary based on material characteristics including density, moisture content, and size distribution, as well as operating conditions.

Question 4

What electrical requirements do these conveyors have?

Accepted Answer

2007 Mellot Stacking Conveyors units are electric-powered conveyors, which typically require 480V three-phase power for motors of this size and application. You will need to verify the exact voltage, amperage, and phase requirements with the seller before purchase. Electric power offers several advantages including lower operating costs compared to diesel, quieter operation, and reduced maintenance compared to hydraulic systems.

Question 5

What does radial movement mean and how does it work?

Accepted Answer

Radial movement allows the conveyor to swing in an arc around a fixed pivot point at the tail or feed end. This enables you to create stockpiles in a semicircular pattern without relocating the entire conveyor. The radial function is typically controlled hydraulically, allowing the operator to position the discharge point anywhere within the sweep radius, maximizing stockpile capacity and eliminating the need for wheel loaders to build or shape piles.

Question 6

What is the hydraulic low tail feature?

Accepted Answer

The hydraulic low tail is a feature that allows the tail or feed end of the conveyor to be lowered close to the ground for easier loading from trucks, hoppers, or other equipment. This reduces the need for elevated feed structures and makes the conveyor more versatile for pit-portable applications. The hydraulic system provides smooth, controlled raising and lowering of the tail section.

Question 7

How do the Beltway Scales work?

Accepted Answer

Beltway Scales are integrated conveyor belt scales that continuously weigh material as it moves along the belt. They use load cells mounted under specific idler rollers in the weighbridge section to measure belt weight, combined with a belt speed sensor to calculate tons per hour and cumulative tonnage. This provides real-time production data without stopping material flow, helping operators track inventory, manage production rates, and generate accurate reports.

Question 8

Are the weighing systems calibrated and accurate?

Accepted Answer

The Beltway Scales on these 2007 units may require recalibration after relocation and installation. Belt scales typically require periodic calibration using test weights or material tests to maintain accuracy. Beltway Scales are known for their reliability and can achieve accuracy within 0.5 to 1 percent when properly installed and calibrated. The integrator or display unit should be inspected to ensure it is functioning properly, and calibration should be performed by a qualified technician after setup.

Question 9

What does 5th wheel pin and pit portable mean for transportation?

Accepted Answer

The 5th wheel pin allows these conveyors to be towed behind a truck using a standard semi-trailer fifth wheel connection. Pit portable means the units are designed to be relocated within a quarry or job site, or transported between sites on public roads. The transport width will depend on the specific configuration, but portable conveyors typically fold or retract components to meet road width restrictions, usually under 12 feet.

Question 10

What is involved in setting up these conveyors on-site?

Accepted Answer

Setup typically involves positioning the conveyor, leveling the unit using hydraulic jacks or stabilizers, connecting electrical power, and adjusting the tail height and radial position as needed. With experienced operators, setup can take 1 to 4 hours depending on site conditions. You will need adequate electrical infrastructure at your site and may need to perform calibration of the belt scales after installation. The seller should provide operation manuals with setup procedures.

Question 11

What Equipment Is Needed to Move and Position 2007 Mellot Stacking Conveyors?

Accepted Answer

Since these have 5th wheel pins, you will need a suitable tow vehicle, typically a heavy-duty truck with fifth wheel coupling, for road transport. For positioning within a site, the conveyors may have powered travel wheels or require a loader or dozer for short moves. Check with the seller about the specific travel and mobility features of these units, as some radial stackers have self-propelled radial travel capability while others require external assistance.

Question 12

What are the main maintenance requirements for these conveyors?

Accepted Answer

Regular maintenance includes belt tensioning and alignment, inspection and greasing of idler bearings, checking and adjusting the belt tracking, inspecting drive motors and reducers, maintaining the hydraulic system including oil levels and filter changes and cylinder inspection, and periodic calibration of the weighing system. The conveyor belt itself is a wear item that will eventually need replacement depending on material abrasiveness and operating hours.

Question 13

Are replacement parts readily available for 2007 Mellot conveyors?

Accepted Answer

Mellot, also known as Mellott, is a well-established manufacturer that continues to operate, so many standard components like idlers, bearings, belting, and hydraulic parts should be available through the manufacturer or aftermarket suppliers. The Beltway Scales components are also from an active manufacturer with good parts support. However, at 18 years old, some proprietary or obsolete electrical components might be more difficult to source. Request parts availability information and maintenance records from the seller.

Question 14

What is the typical service life of major components?

Accepted Answer

Conveyor belts typically last 3 to 7 years depending on material abrasiveness, with more aggressive materials like recycled concrete wearing belts faster. Idler bearings can last 5 to 10 years with proper maintenance. Drive motors and gearboxes can last 15 to 25 years with regular servicing. Structural steel frames can last decades if properly maintained and protected from corrosion. At 18 years old, these units have likely had belt replacements and may need bearing updates, but the main structure and frames should have significant life remaining.

Question 15

Is $15,000 per unit a good value for these conveyors?

Accepted Answer

At $15,000 per conveyor, these represent significant savings compared to new radial stackers which typically cost $80,000 to $200,000 or more depending on size and features. The price reflects the age of 18 years and used condition, but these can still provide excellent value if they are in good mechanical condition. Key factors to evaluate include structural condition of the frame and truss, condition of the conveyor belt, functionality of the hydraulic systems, operational status of the belt scales and integrators, and availability of maintenance records. Consider having a qualified inspector examine the units before purchase, especially checking for frame cracks, worn components, and hydraulic system integrity.
