What sets us apart?

Hydraulic System
With three pumps, each one only operates at the minimum pressure needed to carry the load. One pump runs the gutter brooms, one runs the elevator, and one runs the main broom.
Elevator Wear
Results up to 10.8 million revolutions on elevator before rebuild while sweeping millings/road grindings.

Hopper Capacity
Largest hopper capacity in its class. Total volume of 5.9 Cubic Yards with usable net capacity of 4.9 CY. 
INTERACTIVE 3D COMPONENTS
Standard Features
Truck Chassis
The X-Broom can be built with either an International 4400 chassis or a Freightliner M2 chassis. The International comes with a 310 HP, 950 Ft-lb torque Maxforce 9 engine. The Freightliner comes with a 300 HP, 860 Ft-lb torque Cummins engine. Both meet 2010 emissions. The Cummins engine uses SCR technology and the Maxforce 9 uses EGR emissions control and does not require diesel exhaust fluid. Both chassis have 50 gallon fuel tanks, Allison transmissions, power and heated mirrors, dual steering and controls, Chalmers suspension, and 23,000 lb 2-speed rear axle.
Hopper
Largest hopper capacity in its class.  Total volume of 5.9 Cubic Yards with usable net capacity of 4.9 CY.  The hopper is larger because of no scissor lift underneath and higher because of a longer elevator.  Large discharge door to dump load in the center of truck.  Dual hydraulic door cylinders.  Hopper loading can be viewed from the cab window or two access doors on either side.  The hopper can be dumped from any height.  The hopper floor is a formed 3/16” plate for extra strength.
Lift System
Unique fork lift style mast enables a larger volume hopper and completely opens the middle of the truck frame for maintenance and cleaning. With the mast directly behind the cab, the hopper can extend down to the frame. The 19” of vertical height used on other manufacturers scissor lifts is used for extra hopper volume. All moving parts roll on bearings with no bushings or sliding blocks to wear out. The hopper bottom is lifted to a height of 12’-6” and the lift is rated at 15,000 pounds.
Hydraulic System
The broom uses three separate hydraulic pumps. One pump runs the gutter brooms, one runs the elevator, and one runs the main broom. Each one is a pressure compensated, variable volume piston RexRoth pump. This is much more efficient than using only one pump like most other sweepers. With only one pressure compensated pump, every function operates at the highest pressure needed for any single function. This causes higher horsepower and excess heating of the hydraulic fluid.  With three pumps, each one only operates at the minimum pressure needed to carry the load. The lower horsepower required saves fuel and does not require the engine to operate above idle. There are two valve manifolds mounted close to their functions instead of one large valve. This puts the valves very close to the motors or cylinders minimizing the lengths of hoses. The 45 gallon hydraulic tank is mounted directly behind the cab, high on the left side. This keeps the tank away from the dirt and provides better suction flow to the pumps. There is a large in-tank 10-micron return filter, glass sight level with a thermometer, and an in-tank float and over-temperature switch for operator warning indicators.
Elevator System
The elevator is a typical drag slat type conveyor. Unique features include 14 replaceable rubber squeegee flights, poly-urethane shaft sprockets, and dual roller chain. The elevator is driven hydraulically with a rigid coupling and torque rod. No chains or sprocket to wear out and replace. The elevator jam indicator is standard, not an option. The speed of the conveyor is variable and can be reversed. The elevator sweeping height is able to be raised and lowered from the cab. The sweeping height can be set into the PLC and this height will be repeated each time the elevator is lowered to sweep.
Gutter Brooms
The gutter brooms are a full floating, trailing arm, air suspended design. The gutter broom speed is variable and the down pressure can be adjusted from the cab. Both brooms are reversible. The extension of the gutter brooms are air powered and the width is infinitely adjustable. The steel broom disk protects from curb strikes and has mounting holes for either 4 or 5 segment replaceable gutter brooms. Each gutter broom has hydraulic tilting left or right from the cab. No failure prone electric actuators.
Main Broom
The main broom is a full 60” wide with replaceable poly or steel wafers. The lift and suspension of the broom is with air operated cylinders. The sweeping down pressure is adjusted by individual left and right side precision regulators. Broom adjustments are much easier with this system than the springs, chains, and adjustment bolts of other systems. The air suspension will automatically compensate as the broom wears. The broom drive is with a floating hydraulic motor rigidly coupled to the broom shaft. This eliminates the wear and replacement of chains and sprockets.
Control System

The control used on the X-Broom is an industrial grade Programmable Logic Controller (PLC) with a touch-screen display panel. All functions of the broom are controlled by the PLC. This enables fully automatic operation of the sweeping operation. The operator just touches a “Start” button and the PLC activates the functions needed to sweep. This involves starting, lowering, and extending the gutter brooms, starting the elevator and lowering to the desired height, lowering the skid shoes and main broom, starting the broom motor, opening the water spray valves and starting the water pump(s). The PLC always monitors the position of the elevator, ensuring that is fully forward before starting. It also monitors the hydraulic temperature and level and will raise all brooms if the transmission is placed in Reverse. There is a “Pause” button that will stop the brooms and water sprays if the sweeper has to stop for traffic without raising the brooms or elevator. The “Stop” button will stop and raise all brooms and the elevator will continue to run for 5 seconds to empty out.


The PLC has an hour meter for each broom, the elevator, water pump, hydraulic fan, and PTO. The PLC also keeps a count on how many times the hopper has dumped. This lets you track broom wear to actual operating hours of the individual broom. 

 

There is a screen for Manual Operation of each function for testing and diagnostics. The buttons also gives a visual indication of what is “on” and the status of each limit switch. The PLC greatly simplifies the wiring to the valves and solenoids on the broom.


The hopper dumping functions can be either be controlled from the touch-screen or from a joystick on the front panel. When the hopper needs to be dumped, the PLC will move the elevator back before raising the hopper, then ensure the hopper is down before moving the elevator to the forward position.

Water System - PM10 Certified
The water system consists of two electric pumps. One is variable speed for maintaining pressure with a different numbers of tips on. The other is a fixed volume for extra water flow for dusty conditions. The operator can select an “Economy” mode for low water use or a “Max” mode for dusty sweeping conditions. The standard water tank is 300 gallons with an optional 50 gallons. The pumps can run dry without damage. A front spray bar is standard along with 3 spray tips on each gutter broom and a spray bar in front of the main broom. The system pumps and tips are designed for misting, (smaller drop size), doing a better job knocking down dust while minimizing water use.
Arrow Board
There are two types of arrow boards available on the X-Broom. The standard arrow board consist of 13 oval amber lights. There is also an optional 25 round light arrow board with advanced flash capabilities. The Standard/Advanced Button on the SETUP screen will be set at the factory and should not be changed by the user or improper operation will result. There is a setting on the SETUP screen that lets you determine if you only want the arrow board to flash only when the PTO is engaged or flash anytime.
