Tipping Solutions

The Alpha series cylinder is engineered to help you work more efficiently. Its faster tipping speed reduces turnaround times, while longer service intervals increase your overall operating time. By delivering a safer, more reliable solution, the Alpha series also minimises downtime and keeps your equipment performing when it matters most.

At HYVA, we focus on delivering complete solutions that meet your requirements quickly and effectively, not just supplying a cylinder. Our products are tailored to specific market segments, offering an optimal balance of weight, performance, and cost. With one of the widest cylinder ranges available, from 5 to 100 tons, we also provide bespoke options when needed.

Our Heavy Duty (HD) Series delivers exceptionally fast tipping, thanks to broad overlaps and dual rod seals. High-quality guide rings, durable hydraulic seals, and maintenance-free spherical plain bearings ensure long-lasting performance. The cylinders operate at working pressures up to 250 bar and remain easy to service throughout their lifespan.

Every new product undergoes extensive field testing to ensure it meets the expectations of real-world users. The entire system has been re-engineered from the ground up to provide the best results when installed as a complete end-to-end solution.

The HYVA Alpha Series offers a complete solution that includes both the cylinder and the wetkit, delivering maximum performance at minimal weight with the shortest possible tipping cycle. HYVA hydraulic systems are constructed from high-quality, durable components designed to work seamlessly with every truck type and withstand the most demanding applications.

Each system undergoes rigorous laboratory testing (both at the component level and as a complete solution) before leaving the factory, ensuring reliable performance in the field.

HYVA supplies a high-quality air breather with every oil tank, as it is an essential component of every hydraulic installation. Its primary role is to protect the system from dust, moisture and other environmental contaminants that can cause serious and costly damage. Engineered for reliability, the HYVA air breather is built to perform in even the toughest conditions, including heavy-duty mining, and its effectiveness has been proven worldwide.

Benefits:

• Easy to access and inspect
• Anti-splash protection feature
• High air flow rate of 1350 l/min
• Filtering capability of 10 microns
• Robust, durable design to withstand vibration
• Protection against airborne moisture and particulate contamination

HYVA provides return oil filters suitable for a wide range of hydraulic applications, and they can be mounted on any of our oil tank configurations. These filters are engineered for high efficiency and designed specifically for truck environments, where vibration resistance is critical.

Available in nominal flow capacities of 150 l/min and 250 l/min for heavy-duty use, HYVA filters support safe, long-term system performance. By protecting hydraulic components and preserving oil quality, they significantly reduce the risk of unexpected failures and costly repairs.

Benefits:

• Plate type designed to mount the valve directly on the filter plate
• The house type is designed to connect the return hose directly to the filter housing
• Glass-reinforced PA return line filter inner housing
• Extension tubes are applicable to avoid oil foaming
• Available in standard and high flow versions

HYVA’s single- and dual-section pneumatic controls are compact, lightweight, and easy to mount, thanks to their cast body design. They offer multiple mounting options for flexible operation and are available in configurations for tipping only or tipping with PTO control. Each unit features an ergonomically designed hand lever and proportional lowering for smoother, more accurate handling.

For applications requiring more functionality, multi-sectional controls manage the tipping cylinder, along with additional operations such as rear-door opening, sheeting systems, and sideboards. HYVA provides modular controller sets that can be configured to suit the exact number of control sections required. These systems use a slim, three-way modular design with multiple actuation options, including double-acting, single-acting and PTO on/off, making custom configuration straightforward and adaptable to any application.

HYVA’s HT tipping valve series is purpose-designed for tipper applications and plays a critical role in both system safety and overall wet-kit performance. Drawing on global experience across all tipping environments, HYVA has developed a renewed range of HT valves built on a proven design concept recognised as one of the safest solutions in the industry.

The HT family includes models with oil flow capacities of 150 l/min and 220 l/min, with mounting options either on the tank (TNK version) or directly on the cylinder (SAE version). Valves are available in single or dual working-pressure configurations, with pressure changes controlled mechanically (MS) or by air (AS). This versatility ensures the HT range can support any application across global markets.

Benefits:

• Safer operation due to unique design
• Fixed working pressure concept with replaceable cartridges
• Better precise control of the tipping operation
• Proportional operation of lowering for precision and safety,
• Longer lifetime with hardened spool
• Possibility to mount directly on the cylinder or oil tank
• Acting as a hose burst valve if mounted on the cylinder directly
• Adjustable lowering speed.

Multi-section tipping valves

For tipping applications that require additional hydraulic functions, HYVA offers multi-section valves with up to four sections. Each section can be configured for single- or double-acting applications and is air-controlled with adjustable working pressure. These valves support oil flows between 80 and 160 l/min, making them suitable for a wide range of operational needs.

Knock-off valves

The standard knock-off valve (STD) is mounted on the cylinder cradle and supplied with a dedicated bracket for easy installation and precise adjustment. Pneumatically operated and mechanically adjustable, it is compatible with the full range of HYVA front cylinders. Its controlled stroke limitation ensures smooth operation and significantly extends the life of both the cylinder and the hydraulic system.

The heavy-duty knock-off valve (HD) mounts directly onto the Alpha HD cylinder using a specially designed bracket. With a longer piston stroke, it provides smooth, precise deceleration of the tipper cylinder. The reinforced HD version is built for the most demanding applications and harsh working conditions.

Benefits:

    
• Increased the lifetime of the complete hydraulic system and the cylinder
    
• Easy installation and adjustment of the valve
    
• Increased tipping speed allowed with the knock-off installed
    
• Fine-tune the exact tipping angle.

Hose guide arms

HYVA hose guides are designed for use with tractor wet kits to protect hydraulic hoses and improve hose management between the tractor unit and semi-trailer. They help prevent wear and damage in applications such as tippers, walking floors and silo trailers.

Swivel arm

The swivel arm hose guide is a heavy-duty solution suitable for a wide range of tractor configurations. Available in different shapes and lengths, it allows operators to minimise built height while maintaining efficient hose routing. The arm rotates on a reinforced swivel joint engineered for high-pressure use.

Hydraulic Cross Beam (HCB)

The HCB is a simple, plug-and-play hose guide designed explicitly for tractor wet kits that use flexible hoses. It protects hoses from accidental damage or abrasion while allowing for the natural movement between the tractor and semitrailer.

Hyfix and polyp gripping device

HYVA’s Hyfix body clamp and polyp gripping device secure the tipper body in its lowered position when driving empty. By preventing unwanted movement, they reduce vibration, noise and premature wear of tipper components. The Hyfix clamp is suitable for rear-unloading tippers, while the polyp clamp works for both rear- and side-unloading models. Both options are available in steel or aluminium.

Benefits:

• Reduced vibrational stress and wear on the tipper body
• Increased lifetime of the tipping cylinder
• Reduced wear of hydraulic seals, cylinder brackets/hinges
• Create a fixed connection between the tippers body and chassis
• Reduced noise while driving empty.

Every wetkit is supplied with a complete set of hoses and adaptors, available in various types to suit different applications. HYVA offers a comprehensive range of high-quality components specifically designed for truck hydraulic systems. These parts play a critical role in overall system performance, safety and durability, directly influencing how reliably the equipment operates over its lifetime.
