How the SINOLIFT GL20A / GL20B Manual Stacker combines a detachable frame, foldable forks, controlled hydraulic lowering, quiet wheels, and simple serviceability for light-duty material handling.
The GL20 Series is aimed at workplaces that need a simple manual lifting solution without the footprint or complexity of powered equipment.
In many warehouses, workshops, logistics rooms, and service areas, the handling task is not about moving multi-ton pallets. It is about lifting smaller loads to a practical working height, repositioning goods over short distances, and keeping equipment easy to store or transport when the job is done. The GL20A and GL20B address that type of work with a 200 kg rated capacity, a 900 mm maximum fork height, and a detachable split-frame construction. The result is a compact manual stacker that focuses on portability, straightforward operation, and manageable maintenance.
Useful for light stock movement, positioning cartons or small palletized loads, and supporting routine material transfer where powered lifting is unnecessary.
Helps position tools, components, parts, or assemblies at a more convenient handling height while retaining a compact manual footprint.
The detachable frame and compact packing format support transport between facilities, while the lightweight structure makes local repositioning easier.
Foldable forks and split wheel-bracket construction make the stacker practical for sites where storage space and service access matter.
The 200 kg capacity is suited to repetitive movement of smaller materials and components within light-duty production and assembly environments.
Quiet wheel design and controlled manual operation suit environments where noise, maneuverability, and easy equipment sharing are important.
The GL20 Series is less about complexity and more about thoughtful mechanical details that make routine work easier.
The body can be disassembled into a more compact format for packing and shipment. According to the product design description, this improves delivery convenience, can reduce freight burden, and helps protect painted surfaces during transportation. For distributors, rental fleets, or users moving equipment between sites, this modular structure also makes the stacker easier to handle when it is not in active service.
The hydraulic cylinder is designed to lower the forks faster with light loads and more slowly with heavier loads. That behavior balances productivity and control: operators do not need to wait unnecessarily when handling light items, while heavier loads descend in a more moderated way. The feature is especially relevant in routine manual work where the same stacker may handle different load weights throughout the day.
Each model uses 575 mm forks with a 500 mm overall fork width. The forks can be folded, supporting easier storage, transport, and disassembly. In compact facilities, this matters because a manual stacker often spends part of the day parked against a wall, stored in a service area, or moved by vehicle to another location. Folding the forks helps reduce obstruction when the equipment is not carrying a load.
The GL20 Series combines aluminum alloy wheel components with quiet tire designs to reduce operating noise and improve maneuverability. The product documentation also highlights silent solid-core tires as a durable and labor-saving choice. For indoor workshops, warehouses, and service areas, smooth manual movement can be just as important as lifting performance because operators frequently reposition the stacker over short distances.
The axle and wheel bracket use a split-type design intended to simplify assembly, maintenance, and replacement of parts. This is a practical advantage for equipment that is expected to remain easy to own over time. Instead of treating maintenance as an afterthought, the GL20 design makes access and component replacement part of the core structure.
Both models share the same basic lifting dimensions and 200 kg capacity, but the GL20B adds a mechanical hand brake. The upgraded brake concept includes a self-locking function and is intended to improve control on ramps or downhill sections. Users who work on level indoor floors may prefer the lighter GL20A, while applications that need additional braking control can select the GL20B.
The two models share the same core platform. The main selection point is the braking configuration and the small difference in rear-wheel specification and net weight.
| Factor | GL20A | GL20B | Selection Consideration |
|---|---|---|---|
| Rated capacity | 200 kg | 200 kg | Same light-duty lifting capacity. |
| Maximum fork height | 900 mm | 900 mm | Same vertical working range. |
| Brake system | Standard | Mechanical hand brake | GL20B is the better fit where added braking control is desired. |
| Rear wheel size | 250 × 50 mm | 250 × 45 mm | Slight configuration difference between models. |
| Net weight | 37.7 kg | 40 kg | GL20A is slightly lighter; GL20B adds brake hardware. |
| Packing dimensions | 1250 × 550 × 200 mm | 1250 × 550 × 200 mm | Both use the same compact packed envelope. |
The comparison above is based on the supplied specification sheet. Both models use a detachable frame and the same fork dimensions, lifting height, overall height, and rear wheel track width.
Core dimensions and capacities for selecting between GL20A and GL20B.
| Specification | Unit | GL20A | GL20B |
|---|---|---|---|
| Frame Type | — | Detachable | Detachable |
| Brake System | — | Standard | Mechanical Hand Brake |
| Rated Load Capacity | kg | 200 | 200 |
| Max. Fork Height | mm | 900 | 900 |
| Min. Fork Height | mm | 85 ± 2 | 85 ± 2 |
| Fork Length | mm | 575 | 575 |
| Fork Width | mm | 70 | 70 |
| Overall Fork Width | mm | 500 | 500 |
| Inside Fork Width | mm | 360 | 360 |
| Overall Height | mm | 1240 | 1240 |
| Front Wheel Size | mm | 40 × 40 | 40 × 40 |
| Rear Wheel Size | mm | 250 × 50 | 250 × 45 |
| Rear Wheel Track Width | mm | 730 | 730 |
| Net Weight | kg | 37.7 | 40 |
| Packing Dimensions (L × W × H) | mm | 1250 × 550 × 200 | 1250 × 550 × 200 |
The GL20 Series is most relevant when compact handling, easy transport, manual operation, and straightforward upkeep matter more than high lifting capacity.
Warehouse teams handling small loads, cartons, components, or light palletized goods within a 200 kg capacity.
Workshops that need a compact lifting aid for positioning parts and materials at a practical working height.
Distributors and users who benefit from detachable construction and compact 1250 × 550 × 200 mm packing dimensions.
Facilities where quiet manual movement and a relatively lightweight machine are preferred for indoor handling.
Maintenance teams that value split-type axle and wheel-bracket construction for easier assembly and servicing.
Operations that need a choice between a standard configuration and a GL20B model with mechanical hand braking.
The core value of the GL20A / GL20B is not a single headline specification. It is the combination of manageable weight, compact transport, foldable forks, controlled hydraulic lowering, durable rollers, quiet wheel construction, and accessible maintenance. For light-duty applications, these details can make a manual stacker easier to integrate into everyday work because the equipment remains simple to move, store, assemble, and service. The GL20A offers the lightest configuration at 37.7 kg, while the GL20B increases net weight to 40 kg and adds a mechanical hand brake for applications that benefit from additional braking control. Both models retain the same 200 kg rated capacity and 900 mm maximum fork height, so the choice can be made around site conditions rather than lifting performance.
