How to Choose a Stacker Crane Manufacturer for Your AS/RS Project
Choose a stacker crane manufacturer by matching its engineering and project support to your required load, storage geometry, throughput, operating conditions, and integration needs. Do not compare suppliers on equipment price alone: verify how each one turns your data into a coordinated AS/RS design, and clarify who is responsible for racks, controls, installation, commissioning, and after-sales support. At HEGERLS, we recommend starting with the project requirements and evaluating the supplier’s proposed solution against them before discussing final specifications or cost.
Start with the AS/RS problem you need to solve
A stacker crane is part of a larger automated storage and retrieval system, not a stand-alone purchase. Its performance depends on the aisle, rack structure, pallet or load characteristics, warehouse management interfaces, and the movement of goods into and out of storage. A crane selected without considering these relationships may not meet the operation’s actual throughput or storage objectives.
Before contacting manufacturers, define the current constraint and the intended outcome. You may be seeking greater storage density, more consistent handling, improved inventory control, or a new automated warehouse for a particular product range. These goals influence crane configuration, rack design, controls, and the level of integration required.
How to evaluate a stacker crane manufacturer
1. Prepare a clear project brief
Give each potential supplier the same baseline information so that proposals can be compared fairly. Include the building layout, clear height, aisle count, rack arrangement, load dimensions, maximum load weight, and the expected inbound and outbound flow. Also describe the facility’s environmental conditions, shift pattern, expansion plans, and any operational restrictions.
Use real operating data where available, and identify estimates as estimates. For example, a preliminary brief might describe a maximum load of 1,000 kg, a storage height of 30 m, and a target flow of 30 pallet movements per hour. These are illustrative planning figures, not universal design recommendations or HEGERLS equipment guarantees; the appropriate values depend on the project and must be verified in engineering.
2. Check whether the supplier understands your loads and layout
Ask how the manufacturer will confirm that the crane and rack design suit the loads you actually handle. Pallet quality, load overhang, packaging stability, and variations in dimensions can all affect storage and retrieval. A supplier should request relevant load data and explain how unresolved variations could affect system design or operation.
Review the proposed configuration in the context of your building. Ask how the supplier accounts for aisle geometry, rail and rack interfaces, clearances, access for maintenance, and any floor or structural information required for design. If your facility has unusual constraints, request a written explanation of the assumptions behind the proposed solution.
3. Assess engineering and system integration
A capable project partner should explain the boundaries between the crane, racking, conveyors or transfer equipment, control system, and warehouse software. Confirm which party is responsible for each interface, what information is required from your IT and operations teams, and how changes will be managed. If several vendors are involved, ask who coordinates the overall technical scope.
Discuss operating modes, safety functions, fault handling, and recovery procedures early in the project. Request documentation describing the proposed controls and the information exchanged with your warehouse management system. Avoid treating a general statement such as “integration is included” as sufficient until responsibilities, assumptions, and deliverables are documented.
4. Evaluate the manufacturer’s delivery and support plan
Ask for a project plan that identifies design reviews, manufacturing or procurement stages, delivery, installation, commissioning, and handover. Confirm what site preparation is needed and which activities are performed by the supplier, your team, or other contractors. The schedule should be based on the project scope and dependencies rather than an unsupported standard lead-time promise.
HEGERLS supply professional and honest service.
After-sales arrangements deserve the same attention as the initial delivery. Ask what technical documentation, operator training, spare-parts information, and service options are available for the proposed system. Clarify how support requests are handled, which components are included in the service scope, and whether remote assistance depends on your facility’s IT and security policies.
Key decision points when comparing proposals
Compare scope, not just the equipment line item
Two quotations may describe different project boundaries even when both use the term “stacker crane.” One may include rack integration or controls coordination, while another may exclude those items or list them as optional. Compare the complete scope, including engineering, interfaces, installation responsibilities, commissioning, documentation, and support.
- Technical fit: Does the proposal address your loads, layout, throughput target, and operating conditions?
- Interface ownership: Are responsibilities for racks, controls, software, and material flow clearly assigned?
- Evidence and assumptions: Are design inputs, exclusions, and performance assumptions stated in writing?
- Lifecycle support: Are training, documentation, spare-parts planning, and service expectations defined?
- Commercial clarity: Can you identify included items, optional work, payment milestones, and schedule dependencies?
Ask for evidence that is relevant to your project
Request examples of comparable project scope or technical documentation that the supplier is authorized to share. The most useful evidence demonstrates how the manufacturer addresses similar load types, system interfaces, installation constraints, or service needs. If a supplier cannot share customer details, ask for anonymized technical examples or a structured design review instead.
Also ask how proposed performance figures are defined and validated. Confirm the measurement basis, operating assumptions, and exclusions before using any figure to compare bids. This keeps the evaluation grounded in your required operating conditions rather than headline numbers that may have been calculated differently.
Common mistakes to avoid
- Choosing by price alone: A lower equipment price may not include the same engineering, interfaces, installation, or service scope.
- Using incomplete load data: Designing around idealized pallets can leave real-world dimensions or load stability unaddressed.
- Setting throughput without a flow analysis: A target should reflect inbound and outbound patterns, bottlenecks, and the full system—not only crane travel.
- Leaving software and control interfaces until late: Late clarification can create avoidable design changes and coordination work.
- Assuming support is automatic: Training, spare parts, and service response expectations should be agreed rather than presumed.
Improve the selection process before placing an order
Use one requirements document for every bidder and ask suppliers to respond against the same headings. Separate confirmed facts from assumptions, and record open questions with an owner and a resolution date. This makes technical gaps and commercial exclusions easier to spot before they become project changes.
Invite operations, engineering, IT, procurement, and maintenance stakeholders into the review. Each team sees different project risks: operations can explain flow patterns, IT can clarify data and security requirements, and maintenance can assess access and service needs. A supplier workshop can help resolve conflicting inputs before the design is finalized.
How HEGERLS can support your evaluation
As a provider of stacking racks and shelves and AS/RS-related solutions, HEGERLS can discuss your project requirements and help assess how storage structure, stacker crane selection, and system interfaces fit together. We encourage buyers to share layout drawings, load specifications, throughput expectations, and project constraints so that the discussion can focus on practical design questions. The final configuration, technical details, schedule, and scope should be confirmed against the project’s verified information.
When comparing HEGERLS with other manufacturers, apply the same checklist and request clear written answers on scope, assumptions, integration, and support. This gives your team a consistent basis for deciding whether a supplier is suitable, regardless of brand or quotation format. It also helps identify where additional site data or engineering review is needed.
Summary and next steps
The right stacker crane manufacturer is the one that can demonstrate a clear fit between your operating requirements and its proposed system, while making project responsibilities and support expectations transparent. Begin with accurate load, layout, and flow data; compare complete proposals; and verify technical assumptions before committing. A structured evaluation reduces uncertainty and helps prevent important interfaces from being overlooked.
To move forward, prepare your project brief and request a technical review from qualified suppliers. Include your facility drawings, load information, operating targets, integration needs, and expected project schedule.
