The included hoist-ready design accommodates a broad range of dump bodies, helping users expand capabilities without sacrificing reliability. This option is well-suited for contractors and operators who routinely lift heavy loads and require consistent performance across long operational hours.
7k 90″ Telescopic Dump Trailer Kit (Hoist Only)
This hoist-only variant mirrors the standard kit’s strength and reach while focusing on upgrading or replacing the hoist portion of an existing dump system. It shares the same high-grade materials and high-flow power unit approach to ensure quick lift cycles and dependable performance under heavy loads. The 90-inch stroke supports deep dumping action, enabling efficient unloading of bulky materials such as gravel, soil, and debris. Easy retrofitting can reduce downtime and extend the life of older equipment.
Key features include durable construction designed to handle >20 tons of payload, compatibility with a broad set of dump bed configurations, and a hydraulic power unit tuned for rapid, repeatable dumping sequences. For operators maintaining mixed fleets or those who want to upgrade their current hoist hardware, this option provides a strong balance of power, reach, and installation simplicity.
12K 108″ 30+ Ton Dumping Capacity (EF-12-108-H)
This high-capacity cylinder is built to handle up to 30 tons of payload with an 108-inch stroke, delivering extended reach for heavier dump applications. The telescopic design provides a versatile range of motion, enabling precise control for loading, lifting, and tilting operations. Heavy-duty bracketry and mounting hardware reinforce stability under substantial loads, reducing wear and maintenance needs in harsh job-site conditions.
With a focus on versatility, this model supports a broad spectrum of trailer lengths from 10 to 14 feet and is designed to perform consistently in both cold-weather environments and dusty construction sites. Operators can expect smooth operation, minimal drift, and reliable cycle performance across repetitive dumping tasks.
12K 108″ 30+ Ton Dumping Capacity (EF-12-108-SK)
The standard kit variant emphasizes robust performance for heavy-duty dump operations with a 108-inch stroke. It features a high-flow hydraulic power unit and upgraded #8SAE ports to improve efficiency during dump cycles, ensuring rapid retraction and extension. The heavy-duty mounting hardware reinforces stability under large loads, supporting long service life in demanding environments.
Ideal for fleets prioritizing maximum payload and consistent dumping cycles, this model balances high strength with practical installation considerations. The combination of heavy-bracket construction and optimized hydraulic performance helps maintain uptime across challenging job sites and frequent use scenarios.
Maxim 12 Ton Single-Acting Telescopic (210703)
Maxim’s 12-ton single-acting telescopic cylinder offers a compact 78-inch stroke in a three-stage design. Suited for trailers where space is limited but extended reach is required, it retracts to a compact length without sacrificing lifting power. The unit uses a chrome-plated rod and precision-machined body for corrosion resistance and durability in tough trailer applications. This option is well-suited for fleets seeking a reliable, space-efficient solution that still delivers substantial lift capacity for dump operations and pack-and-eject workflows.
Maxim 7 Ton Single-Acting Telescopic (210701)
This 7-ton single-acting cylinder is designed for trailers requiring a balance of compactness and reach. The three-stage design yields a full 90-inch stroke, with a retractable length of 39.5 inches, making it a practical choice for tight spaces. As with other Maxim models, it uses a durable construction with chrome-plated rod and corrosion-resistant materials to withstand daily trailer use in varied environments.
Maxim 7 Ton Single-Acting Telescopic (210702)
This variant presents a 7-ton capacity with a 108-inch stroke, enabling a longer reach while preserving compact retraction. Built to endure heavy-duty trailer use, it features a triple-stage design, a chrome-plated rod, and a high-quality interior finish to reduce wear and improve efficiency during repeated cycles. It’s a strong option for applications requiring reach without excessive footprint.
Buying Guide: Key Considerations For Telescopic Dump Trailer Cylinders
- Load Capacity and Stroke: Match the cylinder’s rated capacity and stroke length to the trailer’s payload, body length, and desired dump angle. Higher tonnage tires working in rocky or sandy sites benefit from longer strokes for full bed tilt.
- Mounting Hardware And Brackets: Ensure robust H-brackets and upper mounting hardware are included or compatible with your current frame. Poor mounting can cause misalignment and accelerated wear.
- Hydraulic Compatibility: Check port size (#8SAE as noted), flow requirements, and compatibility with your existing hydraulic power unit to maximize efficiency and cycle speed.
- Material And Durability: Look for chrome-plated rods, corrosion-resistant alloys, and micro-honed interiors to extend service life in harsh environments and frequent cycles.
- Installation And Downtime: Consider how easily the cylinder can be integrated into your current system. A modular or hoist-only option can minimize equipment downtime during upgrades.
- Maintenance And Spare Parts: Favor models with widely available replacement seals, rods, and brackets, and check the availability of service documentation from the manufacturer.
- Space Constraints: For trailers with restricted under-body space, select shorter retract lengths and longer stroke cylinders to achieve the needed reach without overhang.
- Application Fit: Align cylinder design with intended tasks—dumping, loading, tilting, or pack-and-eject sequences—to ensure smooth operation and safe handling of materials.
- Cost of Ownership: Factor in the total cost of ownership, including potential maintenance, downtime, and compatibility with current fleet hardware.
- Warranty And Support: Review warranty terms and the availability of technical support and installation guidance from the brand.
