Features
Standard features on the CP 400 D
400-Gallon Capacity
- The 400-gallon material tank maximizes uptime by reducing reloads during high-production crack sealing operations.
All-Diesel Power
- Simplify fueling at the jobsite with a single diesel source that powers both the burner and the engine for dependable performance.
Oil-Jacketed Melting System
- The Crack Pro Heated Hose Machine has an oil-jacketed melting system that safely heats and maintains the temperature of hot-pour crack-sealing materials.
- The oil-jacketed “double boiler” design surrounds the material tank with heat-transfer oil to deliver consistent, uniform heat without direct flame contact. This helps prevent polymer-modified crack sealants from scorching while maintaining proper application temperatures for better material performance and longer kettle heat retention.
Heated Hose System
- State-of-the-art heated hose maintains material temperature from the kettle to the point of application while eliminating the need for flushing.
- By keeping material hot from start to finish, contractors can spend less time on cleanup and more time sealing cracks.
Counterbalanced Hose Boom
- Reduce operator fatigue and improve hose handling with an ergonomic counterbalanced hose boom designed for easier movement and greater control during application.
Lightweight Aluminum Wand
- Designed for operator comfort, the lightweight aluminum wand includes a crack-sealing shoe for improved application control and reduced fatigue during extended crack-sealing projects.
- The lightweight aluminum construction improves maneuverability, making it easier to follow winding cracks, navigate pavement contours and precisely place material.
- Naturally resistant to rust and corrosion, the aluminum wand is built to withstand moisture for long-lasting durability.
Horn Button on Wand
- The integrated horn button on the application wand allows crew members to communicate with the machine operator without leaving their positions.
Fast Heat-Up & Recovery
- Spend less time waiting and more time sealing with one of the industry’s fastest heat-up and recovery systems, ready to apply material in one hour.
Full-Sweep Hydraulic Agitation
- Keep hot pour crack sealant thoroughly blended throughout the workday with direct-drive full-sweep hydraulic agitation featuring forward and reverse controls.
Waterproof Digital Control Center
- The waterproof control center houses all major machine controls and monitoring systems, including:
- Hose Temperature
- Material Temperature
- Heat Transfer Oil Temperature
- Pump Controls
- Agitation Controls
- Audible Horn Controls
- Safety Interlocks
- The Digital Control Center is protected by a durable steel cover to help shield controls from the elements and harsh jobsite conditions.
Electro-Hydraulic Manifold
- The electro-hydraulic manifold integrates electronic controls and hydraulic valves into a centralized system for smooth, dependable machine operation.
- Independently adjust pump and agitation speeds to maintain proper material mixing while optimizing material flow for varying crack widths and application conditions.
- By reducing the number of hydraulic hoses and fittings, the compact manifold design helps minimize leak points while simplifying maintenance.
Liquid-Cooled Diesel Engine
- The Kubota diesel engine provides reliable power while keeping operating temperatures lower for longer engine life and consistent performance.
Beckett Diesel Burner
- Electronically controlled Beckett burners provide reliable heating performance with automatic shutoff and convenient side-mounted access for simplified maintenance.
Anti-Splash Material Loading Hatch
- The hatch is designed to reduce material splash during loading while providing convenient access to the kettle.
Heavy-Duty Trailer
- Built on a heavy-duty trailer with integrated lighting and dependable suspension for reliable towing between jobs.

Optional features
Custom Built to Fit Your Needs

Material Block Conveyor
Enhance productivity by reducing lifting and handling when loading materials into the kettle using a material block conveyor.

Hydraulic Surge Break Assembly
Tow with confidence using a self-contained hydraulic surge brake system that automatically applies smooth, proportional braking without requiring an in-cab brake controller.

2 5/16 Inch Ball Hitch
Increase towing stability with a heavy-duty 2 5/16 inch ball hitch designed to handle heavy loads, even over rough road conditions.Â
Arrowboard
Protect your crew with a high-visibility arrowboard designed to encourage early lane changes and improve traffic flow around the jobsite.
Fire Extinguisher Kit
Add an extra layer of jobsite safety with a 20-pound fire extinguisher kit to help control fires before they spread.

Engine Security Cover
Safeguard the engine from dust, debris and jobsite hazards while helping protect operators from moving engine components.
Tool Box
Stay organized on the jobsite with a heavy-duty toolbox to secure tools during transport.
Liquid Propane (LP) Tank Stand
Keep your LP cylinder secure with a heavy-duty mounting stand that prevents shifting and tipping during transport and operation.

Spare Tire Mount
Secure a spare tire to the trailer for convenient storage and quick access during unexpected roadside emergencies.
15″ Spare Tire Assembly
Stay prepared with a complete 15-inch spare tire assembly that helps minimize downtime.
Application Swivel Discs
Improve application consistency with 2-inch, 3-inch or 5-inch swivel discs that follow the crack for uniform overbanding and precise material placement.

Strobe / Beacon Light
Increase visibility on the jobsite with a high-intensity strobe or beacon light that helps alert approaching motorists.

Overnight Heater Kit
Start sealing sooner by keeping heat transfer oil warm overnight, reducing startup time, fuel consumption and unnecessary downtime.
