Application Overview

In an indoor parts warehouse or distribution center, an order may require cartons and components stored across several rack levels. This application example considers the SINOLIFT MHA10 medium-level electric order picker for bringing the operator to the required picking position and moving picked goods along a planned warehouse route.

The man-up design combines electric travel with elevated operator access, proportional lifting control and auxiliary lift. It can help organize repeated shelf-to-load transfers where rack geometry, the load carrier and the chosen mast configuration suit the task. The supplied technical sheet identifies two open-cab versions: MHA10L with a duplex mast and MHA10S with a triplex mast.

Application Background and Handling Challenges

Warehouse picking differs from moving a complete pallet. Operators may need to identify individual stock items, reach a shelf location and place selected goods onto a compatible load carrier. When order lines span several levels, the task includes repeated vertical access as well as travel between locations.

A workable arrangement must consider shelf height, load size and the operator’s working position. Rack uprights, shelf projections and nearby goods can restrict access. Within the aisle, truck width alone does not establish sufficient clearance: guidance equipment, turning space, cross aisles and the loaded envelope also affect the route.

The SINOLIFT Handling Solution

The MHA10 raises the operator for direct picking access while supporting electric travel between warehouse locations. Proportional lifting and lowering control is designed to provide gradual starts and stops when positioning alongside racking. The selected mast must provide the required operator and load positions without interfering with overhead structures.

The standard auxiliary lift function offers 670 mm of additional adjustment for the picking arrangement. The product description associates this function with reducing repeated bending and squatting. Its exact relationship to the operator platform, fork position and load carrier should be reviewed on the selected configuration.

An ergonomic multifunction handle and thumb switch support operation, while the steering-wheel position display shows steering direction. The supplied copy also describes guardrail and operator presence detection, lifting limits, height-related and turning speed limitations, and safety belt protection. Confirm the fitted protection functions and their operating conditions for the proposed configuration.

The technical comparison covers open-cab MHA10L and MHA10S versions. Enclosed-cab and other customized arrangements are described as available options in the product introduction, without separate technical data in the supplied sheet.

Key Features for This Application

Typical Operating Process

Step 1: Prepare the picking task. Confirm the order locations, shelf heights, load carrier and expected accumulated load. Check the route, selected mast limits and required operator protection conditions before beginning work.

Step 2: Approach the rack location. Use electric travel and the steering direction display to position the truck in the approved aisle arrangement. Allow for the guidance system, load dimensions and clearance from the racking.

Step 3: Raise to the picking position. Use proportional lifting control to bring the operator to a suitable working position within the approved height range. Operate only with the required guardrail, presence and other protection conditions satisfied.

Step 4: Pick and arrange the goods. Retrieve the selected item using the approved shelf-to-carrier method. Use the auxiliary lift adjustment where applicable to the configuration, and keep the accumulated load within the allowed capacity and distribution limits.

Step 5: Continue along the route. Reposition for the next location according to the equipment instructions. The product description supports travel during picking operations, with speed restrictions at height; the listed travel speed must not be assumed to apply at every elevated position.

Step 6: Complete the order handover. Return to the designated transfer position and lower to the required handover height. Transfer the picked load using the agreed carrier and receiving arrangement. Compatibility with a pallet station, conveyor or other device requires a separate interface check.

This sequence illustrates the application and does not replace the operator instructions or the warehouse’s approved working procedure.

Practical Application Benefits

Bringing the operator to the shelf level can help organize picking across several rack heights without repeatedly changing access equipment. Electric travel connects those vertical picking positions along a planned route, supporting order preparation within one handling sequence.

Auxiliary lift adjustment may reduce the need to bend repeatedly when placing goods in the configured picking arrangement. Proportional lifting can also help the operator approach a useful working height more gradually. The practical effect depends on shelf access, item dimensions and how the load carrier is arranged.

The steering display and configuration-specific speed controls support deliberate positioning and movement in the warehouse layout. They do not establish that every narrow aisle or rack installation is suitable. No measured picking-rate improvement, labor saving or customer operating result is claimed for this example.

Relevant Technical Specifications

The supplied technical sheet compares these two open-cab models. Actual operating capacity depends on load position, working height and the approved configuration.

The product introduction describes a maximum lifting height of 6000 mm and a picking height of approximately 7600 mm, depending on configuration. The technical sheet refers lift, picking, free-lift and mast heights to a separate mast parameter table that was not supplied. These headline heights therefore cannot be assigned to either model here. Picking height also differs from the equipment’s lifting height.

The 1750 mm aisle entry is subject to the source’s guidance-system and working-condition qualifications. The source separately states main-aisle requirements of at least (2920 + 400) mm for MHA10L and (2930 + 400) mm for MHA10S, with pallet-size dependence. Confirm the complete aisle design and guidance arrangement. Battery chemistry is not stated for the listed 24 V / 400 Ah configuration; the 24 V / 300 Ah lithium battery is explicitly optional.

Selection Considerations

1. 1

   Shelf heights and mast choice. Provide the highest picking position, required load height, overhead clearance and doorway heights. Obtain the applicable mast table before selecting MHA10L or MHA10S.

2. 2

   Load and picking arrangement. Describe item sizes, maximum accumulated weight, load center, carrier dimensions and the handover method. Confirm auxiliary lift function, load distribution and the allowable capacity at working height.

3. 3

   Aisles, guidance and floor. Share net aisle and main-aisle widths, rack layout, guidance requirements, floor condition and floor loading limits. Include the loaded envelope and the model’s service weight in the layout review.

4. 4

   Duty, battery and operator configuration. Describe picking frequency, travel distances, charging arrangements and operator access needs. Confirm battery selection, cab type, fitted protection functions and height-related operating restrictions.
