The SINTO HNRS4531-5E 45 Ton Electric Reach Stacker is a next-generation heavy-duty container handling machine designed for ports, inland container depots, logistics terminals, freight hubs and industrial facilities seeking to combine extreme lifting capacity with fully electric operation.

With a maximum rated capacity of 45 tonnes in the first row, the HNRS4531-5E is engineered to handle loaded containers and other heavy containerised cargo while providing the flexibility of a telescopic reach-stacker design. The published capacity configuration is 45 t / 31 t / 16 t across the first, second and third rows.

Fully electric power pack with LFP battery technology — a cleaner alternative for modern terminals seeking to reduce local emissions, noise and dependence on diesel fuel.

Container terminals are under increasing pressure to improve productivity while reducing operating costs and environmental impact. The HNRS4531-5E addresses this challenge by combining:

This makes the HNRS4531-5E particularly attractive to ports and logistics operators looking to modernise their container-handling fleets.

45 Tonnes

The published capacity varies according to the container's position:

The actual permissible load must always be determined from the manufacturer's load chart and the exact container position, boom extension, container type and operating configuration.

The HNRS4531-5E is specifically designed for handling loaded shipping containers.

The machine is designed around the requirements of moving, lifting, stacking and repositioning containers within controlled terminal environments.

15,100 mm

This substantial lifting height enables high-level container stacking and efficient utilisation of available yard space. For container terminals, vertical stacking can be critical because land availability and yard capacity directly affect terminal efficiency. The HNRS4531-5E can therefore help operators make better use of available terminal space.

SINTO publishes a stacking capability of:

This provides operators with the opportunity to increase container storage density while maintaining flexible container movement. Higher stacking can potentially reduce the amount of yard space required for a given container volume, subject to terminal layout, safety requirements and operational planning.

One of the most significant characteristics of the HNRS4531-5E is its:

Fully Electric Powertrain

SINTO specifies an electric power pack incorporating:

• High-safety-standard LFP cells
• High-capacity battery modules
• High-strength battery frame
• High energy density
• IP68-level ingress protection for the battery system

The published battery-module options include CATL and BYD. This provides a modern alternative to conventional diesel-powered reach stackers.

The HNRS4531-5E uses Lithium Iron Phosphate (LFP) battery technology. LFP technology is particularly attractive for industrial applications because of its focus on:

For a heavy-duty machine operating in ports and logistics terminals, battery reliability is a critical consideration. SINTO also incorporates a battery heat-management system designed to manage heating, cooling and temperature balance.

8–10 Hours

of continuous operation (depending on conditions and configuration)

Actual operating time depends on factors such as:

SINTO also identifies options including battery changing and container-handler battery replacement arrangements. Wireless and fast charging are identified as development options. For high-volume operations, Sinto Material Handling can help customers develop an appropriate charging or battery-management strategy.

Heavy-duty electric equipment generates significant heat during intensive operation. The HNRS4531-5E incorporates a battery heat-management system designed around:

This is particularly relevant for African operating environments where equipment may be exposed to high ambient temperatures. Battery thermal management can help maintain appropriate operating conditions and support consistent performance. SINTO identifies this heat-management architecture as part of the machine's long-duration operating system.

The HNRS4531-5E incorporates an intelligent platform designed to provide greater visibility over machine operation.

Smart Container Terminal Operations

For large ports and logistics operators, equipment visibility is increasingly important. The HNRS4531-5E can become part of a more connected terminal environment by providing information about:

This can help fleet managers move from reactive equipment management toward more structured preventative maintenance and operational planning.

The HNRS4531-5E uses CAN Bus Communication Technology. This allows electronic systems within the machine to communicate with one another efficiently.

For a sophisticated electric reach stacker, CAN Bus communication supports the integration of:

SINTO identifies CAN Bus communication as one of the machine's operating and intelligence features.

Precise movement is essential when positioning a 40-foot or 20-foot container. The HNRS4531-5E incorporates Proportional Inching Control, providing more precise control during low-speed manoeuvring and container positioning.

It is particularly valuable during:

Handling heavy containers at significant boom extensions requires sophisticated stability management. SINTO incorporates Dynamic Anti-Overturning Control, designed to improve stability management during reach-stacker operation.

The system works alongside the machine's structural design and operating controls to help reduce the risk associated with unstable operating conditions. Operators must nevertheless always follow the manufacturer's load chart, operating limits and safety procedures.

The HNRS4531-5E incorporates anti-collision technology as part of its safety architecture. For busy terminals where multiple machines, trucks and personnel may operate in close proximity, collision-awareness technology can provide an additional layer of operational support.

This should complement, rather than replace:

SINTO identifies multiple protective features within the electric system, including:

The battery system is specified with high ingress protection, while the overall machine incorporates systems intended to improve reliability under demanding industrial conditions.

self-weight

This substantial machine mass reflects its heavy-duty construction and 45-tonne container-handling capability. The machine is therefore intended for properly engineered container-yard surfaces and operating environments.

Before installation or deployment, Sinto Material Handling recommends assessing:

The HNRS4531-5E uses heavy-duty axles supplied by FUWA / KESSLER, designed for the substantial loads and operating demands associated with a 45-tonne reach stacker.

The machine is specified with 18.00-25 × 40PR tyres, designed for the substantial weight and operating requirements of the reach stacker. For African terminals, tyre selection is particularly important because operating surfaces can vary significantly between ports, inland depots and industrial yards.

These characteristics support efficient container-handling cycles.

The exact operational speed should always be determined by the terminal's traffic-management system, load condition and applicable safety requirements.

Actual operating limits depend on:

The HNRS4531-5E is a substantial piece of port machinery. SINTO publishes overall dimensions of approximately:

These dimensions must be considered carefully when planning a terminal layout.

The HNRS4531-5E features an ergonomically designed operator cabin with:

• Wide field of view
• Comfortable seating
• Ergonomic controls
• HMI information display
• Multi-function control interface

SINTO highlights the cabin design and visibility as part of the machine's operator-comfort system. Good visibility is particularly important when positioning containers at height and during close-quarter manoeuvring.

The machine uses an operator interface designed to place major functions within easy reach. This includes proportional control and electronic monitoring designed around efficient container handling. The operator can monitor machine information through the HMI while controlling the machine's primary functions.

Specifications are based on SINTO's published HNRS4531-5E product information. Final specifications should be confirmed against the exact configuration and commercial quotation before publication as guaranteed performance figures.

The HNRS4531-5E gives customers an alternative to conventional diesel reach stackers.

The electric model is particularly attractive for operators pursuing lower-emission terminal operations.

The HNRS4531-5E can be particularly relevant to Africa's rapidly developing logistics infrastructure. As ports and inland terminals expand, operators increasingly need equipment that can provide:

The move toward electric port machinery is becoming increasingly important as terminal operators seek to improve energy efficiency and reduce local emissions. The HNRS4531-5E provides Sinto Material Handling with a specialised product for customers considering port electrification and lower-emission container handling.
