The 2″ rod and 90-degree angled rod end port support versatile mounting options, while the SAE 6 connection ensures compatibility with standard hydraulic fittings.
Primary Mover Single 3.5″ x 30″ Cylinder Direct Push Lift Kit
This kit centers a single 3.5″ diameter, 30″ stroke cylinder with a capacity suitable for trailers requiring a compact, high-throw lift. It’s designed to fit bed lengths from 8′ to 16′, broadening applicability across various trailer sizes. The package includes a complete installation kit, including a double-acting hydraulic power unit, hinges, safety arm, and more, enabling straightforward setup on compatible dump trailers.
Primary Mover 10 Ton Dump Trailer Scissor Hoist Kit
With a 20,000 lb lifting capacity, this scissor hoist kit provides robust performance for mid- to heavy-duty dump trailers. The package includes the cylinder, mounting brackets, hinges, hoses, connectors, a safety bar, and a 12V DC hydraulic pump for a complete power-up and power-down operation. It is designed for 12V systems and offers a 15′ control wire for convenient remote operation.
Primary Mover 12K -108″ Telescopic Dump Cylinder Kit
This high-capacity telescopic cylinder offers a 108″ stroke and heavy-duty strength, capable of lifting over 30 tons in some configurations. The telescopic design provides extended reach and flexibility for different dump body lengths. A sturdy upper mounting bracket and robust hardware support reliable operation under substantial loads, making it suitable for heavy-duty dump applications.
Primary Mover 7k -90″ Telescopic Kit (Hoist Only)
This 7,000+ lb capacity telescopic cylinder with a 90″ stroke is designed for 8’–12′ dump bodies. The kit emphasizes high-flow hydraulic power, optimized for dump bed systems, with port upgrades for SAE fittings. Installation is designed to be straightforward to minimize downtime and ensure compatibility with existing hydraulic setups in compatible dump trailers or trucks.
Primary Mover 8 Ton Hydraulic Scissor Hoist Kit
This 8-ton kit combines a scissor hoist with a power unit designed for reliable dump bed operation on 10’–14′ trailers. Included are mounting hardware, hinges, hoses, connectors, a safety bar, and a 12V DC hydraulic pump. The kit supports straightforward operation and consistent lifting performance essential for routine dumping tasks.
Buying Guide: Key Considerations and Comparisons
Capacity and stroke: Match the cylinder’s rated load and stroke to your trailer length and typical dump height. Telescopic cylinders offer extended reach but can be more complex to install than standard linear cylinders or scissor hoists.
Mounting and compatibility: Check mounting hole patterns, rod end configurations, and bracket hardware. Confirm compatibility with your trailer or truck frame, and verify hose and port types (SAE sizes) to avoid leaks or freedom-of-movement issues.
Hydraulic power unit: Some kits include a complete power unit; others require a separate pump. A higher-flow pump can improve lift speed but may demand more robust hydraulic lines and cooling. Consider control length and ease of wiring for 12V systems.
Durability and materials: Look for heavy-duty materials, corrosion resistance, and robust mounting hardware. Telescopic units typically require stronger brackets and more secure anchoring due to higher loads.
Installation complexity: Kits vary from ready-to-install bundles to assemblies needing custom mounting. Assess your mechanical skills, available space, and the need for extra hoses, safety bars, or hinges when budgeting.
Maintenance and serviceability: Prioritize cylinders with accessible seals and straightforward maintenance schedules. Long-term reliability benefits from manufacturer guidance and readily available replacement parts.
