The WBH-21EFP Whiteman Front-Wheel Drive Power Buggy stands at the forefront of high-capacity material transport technology, delivering unmatched productivity, power, and environmental efficiency for demanding concrete and construction sites. Specially engineered by Multiquip’s Whiteman division, this buggy features a 21-cubic-foot tub, powerful and clean-burning 18 HP Vanguard propane engine, and an advanced hydrostatic front-wheel drive—making it a game-changer for contractors who demand maximum performance, minimal maintenance, and versatile material handling.

Product Overview: WBH-21EFP Whiteman Power Buggy

Designed for heavy-duty use on commercial, industrial, and high-output residential projects, the WBH-21EFP is built to move large volumes of concrete, gravel, debris, or bulk materials quickly and safely. Its substantial payload, durable polyethylene tub, and environmentally friendly powerplant make it ideal for both indoor and outdoor jobs—especially when emission regulations are strict or operating run-time is a key concern.

Key Features and Benefits

• 21 Cubic Foot Tub: The huge, high-density polyethylene tub is durable and lightweight, providing a 21 cu. ft. (595 L) payload capacity and accommodating up to 3,200 lbs. per load for ultimate productivity on every pour.

• 18 HP Vanguard Propane Engine: Clean, powerful, and EPA/CARB-compliant, the propane engine offers extended run times, fast starts (electric or recoil), and significant savings on maintenance and fuel costs—making it perfect for enclosed or air-quality-sensitive environments.

• Hydrostatic Front-Wheel Drive: Infinitely variable, fully hydrostatic drive gives operators smooth speed control, high torque, and seamless shifting between forward and reverse without clutches for safe and precise site maneuvering.

• Superflex Foam-Filled Tires: These high-durability tires provide an air-like ride with puncture-proof longevity, reducing shock to the frame and extending the buggy’s life, especially over rugged, debris-strewn jobsite surfaces.

• Heavy Duty Chassis and Controls: Operator-friendly controls, walk-behind ergonomics, and a robust, low-center-of-gravity design promote operational stability, operator safety, and easy navigation through tight work zones.

Technical Specifications

Performance Advantages

• Extended Run Time: With a large 7.5-gallon propane tank, operators enjoy up to 8 hours of continuous work on a single fill—ideal for large slab pours or material relocation tasks.

• Emission Friendly: Propane technology keeps jobsites cleaner, reduces carbon footprints, and enhances air quality compliance.

• Superior Maneuverability: Front-wheel hydrostatic drive allows for tight turns and positive, controlled stopping even on inclines—safely moving material on uneven, congested, or sloped surfaces.

Durable, Operator-Focused Design

• Poly Tub Construction: Rust, impact, and abrasion-resistant polyethylene tub handles the toughest mixes, including concrete, sand, rock, demolition debris, and more, while being lighter and easier to clean than traditional steel.

• Foam-Filled Tires: Superior to pneumatic models for puncture resistance and smoother ride; ideal for navigating rebar, nails, or sharp material often found on active construction sites.

• Ergonomic Controls: Operator platform and control layouts are dialed for comfort, reducing fatigue in long-haul scenarios and making the buggy intuitive to run—even for first-time users.

Ideal Jobsite Applications

• Large commercial or industrial concrete pours

• Moving demolition rubble on jobs with heavy debris

• Landscape material transport (mulch, soil, gravel)

• Urban or interior jobs where propane and low emissions are required

• Utility and underground construction requiring high payload and compact turning

Accessories and Upgrades

• Bucket insert/liner for wet or sticky materials

• Refillable propane tanks for uninterrupted operation

• Wheel/tire kits (dual or single: optimize for width vs. load)

• Maintenance kits (filters, belts, standard consumables)

• Custom signage/fleet decals for high-visibility or branding
