Zipper ZI-HS22EZ 22-Ton Combined Electric 400V 5100W + Tractor PTO Vertical Log Splitter - Part Number: 930.ZI-HS22EZ

The Zipper ZI-HS22EZ professional combined vertical hydraulic log splitter (part number 930.ZI-HS22EZ) is an industrial-grade forestry machine designed for continuous, high-volume firewood processing both in workshops and directly in woodland environments. Featuring a versatile hybrid dual-drive system, it can be powered by either its built-in 5100 W (S6 40%) 400 V three-phase electric motor with IP54 rating or via a tractor PTO shaft using its heavy-duty Category 1 three-point linkage hitch. Delivering an immense 22 tons of continuous splitting force with a high-capacity 24-liter hydraulic oil reservoir and a generous 948 mm cylinder stroke, it effortlessly splits meter-plus logs up to 1100 mm in length and 80 to 300 mm in diameter. Outfitted with an integrated mechanical log lifter, dual forward speeds (power split and rapid approach), stepless stroke adjustment, and cutting-edge EN 609-1:2017 safety controls, it represents the pinnacle of versatility and power.

Key Features & Engineering Benefits

• Dual Hybrid Drive (400V Electric + Tractor PTO): Provides supreme operational flexibility; plug into 400 V industrial mains when working at the yard/workshop, or attach a cardan PTO shaft for remote woodland processing powered by your tractor.
• Category 1 Three-Point Hitch (Cat. 1): Built-in 3-point mounting frame enables quick lifting, secure transit, and convenient field positioning using standard tractor hydraulics.
• Massive 22-Ton Splitting Thrust: High-pressure commercial hydraulic transmission backed by a 24-liter reservoir easily shears through massive, fibrous, seasoned, or knotted hardwoods (oak, beech, ash, olive) without stalling.
• Extended Meter-Plus Log Capacity (up to 1100 mm): Deep 948 mm cylinder stroke accommodates timber up to 1100 mm in length and 80 to 300 mm in diameter, handling oversized rounds in a single uninterrupted pass.
• Dual Calibrated Forward Speeds: Features a rapid approach speed of 10.5 cm/s to close travel distance swiftly, shifting into a high-torque 4.3 cm/s power stroke to focus all 22 tons on tough grain resistance.
• Integrated Mechanical Log Hoist: Robust linkage-driven side hoist automatically lifts heavy logs from the ground upright onto the base plate, saving operator back fatigue during extended shifts.
• Stepless Travel Stroke Adjustment: Return limiter mechanism allows continuous adjustment of the return stop to match shorter timber sections, eliminating idle return delay and speeding up cycle output.
• Torsion-Resistant Heavy Steel Frame (320 kg): Massive structural steel chassis with a low center of gravity provides rock-solid stability under peak hydraulic tonnage, equipped with wheels for ground positioning.

Technical Specifications

Standard Equipment & Safety Features

Standard Equipment	Operational Benefit
Tractor PTO Splined Drive Shaft	Standard PTO connection allows full hydraulic performance in off-grid field and forest locations
Category 1 Three-Point Hitch	Mounts to standard tractor three-point linkages for rapid site transit and road relocation
Mechanical Log Hoist Assembly	Synchronized linkage lifts heavy timber sections up to 1.1 m upright onto the splitting plate
Two-Hand Safety Levers with Side Claws	Requires simultaneous actuation of dual levers, firmly securing timber and isolating operator hands
Transport Wheels and Positioning Handles	Enables balanced tilt-and-roll maneuvering of the 320 kg unit across paved workshop and yard areas

Operating Guidelines, Dual-Drive Connection & Maintenance:

• 400V Electric Operation: Connect to an industrial 400 V three-phase supply (3P+N+E). Always confirm correct motor rotation upon initial startup before putting the hydraulic circuit under working pressure.
• PTO Operation: Ensure the PTO drive shaft has undamaged protective shrouds and restraint chains. Never exceed the standard PTO speed of 540 RPM to safeguard hydraulic pump components from excessive pressure surges.
• Hydraulic Reservoir Bleeder Screw: Prior to operation under either power source, loosen the hydraulic reservoir breather screw (24 L capacity) by several turns to allow proper circuit venting; retighten it securely before transporting the machine on the tractor linkage.
• Safety & Mandatory PPE: This is a heavy-duty commercial unit (320 kg). Operate solely on firm, level ground. Wearing certified safety boots with steel toes, heavy cut-resistant gloves, and a full face shield or safety glasses is mandatory.
