EKKO EK13S-177 Counterbalanced Walkie Stacker with Side-Shifting — 2,860 lb Capacity at 177" Lift Height
The EKKO EK13S-177 is a fully powered, counterbalanced walkie stacker engineered to deliver the versatility of a forklift in a compact, pedestrian-operated platform. With a 2,860 lb load capacity and a maximum lift height of 177.17 inches (14.75 ft), it is well-suited for loading and unloading trucks, loading docks, stock rooms, manufacturing floors, and general warehousing operations. The unit is built from high-quality steel with robotic welding and durable drivetrain components designed to withstand varied terrain, heavy usage, impact, and frequent directional changes.
Unlike standard walkie stackers, the EK13S-177 incorporates a counterbalanced design that eliminates the need for outrigger legs, enabling operation with a broader range of standard pallets. The integrated side-shifting functionality and adjustable fork width (8.66–28.35 in) add positioning flexibility that reduces repositioning time during load placement — a meaningful efficiency advantage on busy warehouse floors.

Key Features & Benefits
Side-Shifting Forks
The integrated side-shift function allows the operator to laterally adjust fork position without repositioning the entire machine. This directly reduces cycle time during high-frequency load placement tasks and improves accuracy when aligning with racking or truck beds.
Adjustable Fork Width (8.66–28.35 in)
The wide range of fork width adjustment accommodates a variety of pallet sizes and configurations without requiring manual fork swaps. For operations handling mixed pallet types, this translates to less downtime and broader operational flexibility.
Counterbalanced Design with 2°/5° Mast Tilt
The counterbalanced chassis eliminates the need for outrigger legs, enabling the unit to handle standard pallets in tighter spaces comparable to a sit-down forklift. The forward/backward mast tilt (2°/5°) provides additional load control during pickup and placement, reducing the risk of load shift.
EPS (Electronic Power Steering) with Curtis Controller
Electronic Power Steering reduces operator effort during prolonged use, particularly important in high-cycle warehousing environments. The Curtis Controller delivers consistent travel speed across the full speed range and provides a battery discharge indicator to prevent unexpected downtime.
AC Drive Motor with Electromagnetic Braking
The 2.5 kW AC drive motor provides efficient, high-torque performance suited to loaded driving on warehouse floors. Electromagnetic braking delivers precise, secure stopping power, and the electronic neutral braking provides accurate control during load handling.
Heavy-Duty Steel Construction with Robotic Welding
The chassis and mast are fabricated from heavy-duty steel using robotic welding processes, producing consistent, high-strength weld joints throughout the frame. This construction approach supports reliable performance under sustained commercial use and directional load changes.
Polyurethane (PU) Tires with 59.84 in Free Lift
Polyurethane tires are non-marking and well-suited for smooth warehouse and dock surfaces. The 59.84 in free lift height allows significant vertical travel before the mast begins to extend, making the EK13S-177 compatible with low-clearance environments such as trailers and mezzanines.
Common Applications
Loading and Unloading Trucks
The counterbalanced design and 45.28 in fork length allow direct engagement with palletized loads in truck trailers. The free lift height enables vertical movement inside trailer interiors before the mast extends above doorframe height.
Loading Dock Operations
The unit's compact overall width (39.29 in) and 56.89 in turning radius make it maneuverable in the constrained areas typical of loading dock bays. Side-shifting further assists with precise pallet spotting at dock positions.
Stock Room and Warehousing
With a 177.17 in lift height, the EK13S-177 reaches upper rack levels common in high-bay stock rooms. The adjustable fork width accommodates the varied pallet types typically encountered in mixed-SKU warehouse environments.
Manufacturing Floor Material Handling
The electromagnetic braking and EPS steering support controlled, precise movement in production floor environments where fixed machinery and personnel are present. The 70 dB(A) noise rating is compatible with occupied indoor work environments.
High-Bay Racking
The 214.53 in extended mast height allows the machine to service racking systems that would be inaccessible to lower-lift walkies. The 6% loaded gradeability supports operation across floor transitions common in large warehouse facilities.
Compatible Materials
- Standard wood pallets (GMA and non-standard sizes supported via adjustable fork width)
- Plastic pallets
- Smooth concrete warehouse floors
- Dock plates and dock levelers (within 6% loaded gradeability rating)
- Warehouse racking systems (compatible with mast extended height up to 214.53 in)
- Truck trailer floors (non-marking PU tires)
