Güde GSZ 300/600 Electric Chain Hoist – 1.05 kW Motor, 300–600 kg, 11–5.5 m
The Güde GSZ 300/600 hoist is a compact solution for construction sites and workshops requiring horizontal (beam suspension) and vertical (slab, scaffolding) load lifting with flexible capacity. Unlike manual chain hoists (operator fatigue, risk of slipping), the motorized system ensures speed and precise control: the 230V single-phase motor maintains constant pressure without power drops during lifting.
The pulley system (incl. umlenkrolle) is a practical innovation: it allows for doubling the capacity (300 → 600 kg) while using the same 1.05 kW motor, simply by threading the chain through the pulley. Speed is halved (8 → 4 m/min) but allows for safely lifting 600 kg. The 12 m steel chain is divided into 2 sections (6 m effective for single lifting with pulley) allowing versatile application: high slabs 5–6 meters or single beam loads up to 11 meters without extensions. The automatic brake provides extremely high safety; if power is interrupted, the load does not fall but remains suspended, locked by friction.
Who chooses it in Italy
Construction builders lifting prefabricated elements (beams, jambs, panels) prefer it for its lifting speed (8 m/min without pulley) and ease of control. Metalworkers assembling steel structures in the workshop demand it for precise control of heavy loads up to 600 kg without excessive oscillation. Construction equipment rental companies include it in their standard site equipment as it is 230V single-phase compatible (available everywhere) and manually portable (17 kg). In the Krollit catalog, it represents the essential complement for construction sites needing light motorized lifting without investing in crane hoists or fixed systems.
After-sales support and spare parts
Güde supplies replacement chains, hooks, and pulleys in 3–5 days from Austria. Krollit manages a spare parts warehouse in Italy. Routine maintenance: check chain lubrication before each use (apply light chain oil to joints), monthly inspection of hook welds for cracks (replace if required), check control cable for insulation damage. CE and GS TÜV certifications ensure Italian compliance and operator protection.
Who is the Güde GSZ 300/600 hoist suitable for?
| Profile |
Suitable? |
Reason |
| Construction builder / element lifting site |
Ideal |
8 m/min speed without pulley covers rapid lifts. 300 kg capacity sufficient for prefabricated timber axes, medium steel components. 12 m chain covers standard slab heights (5-6 m). Automatic brake and emergency button ensure operator safety. |
| Metal carpenter / steel structure assembly workshop |
Ideal |
Pulley doubles capacity to 600 kg for heavy plates. Precise control of 600 kg load at 4 m/min prevents oscillations. 17 kg portable between job sites. Robust welded hook. |
| Construction equipment rental company / general contractor |
Adequate |
230V single-phase compatibility (site standard). GS TÜV certification meets insurance compliance. However, maximum capacity of 600 kg is a limit for heavy industrial lifts (>1 tonne). For heavier loads, consider fixed crane hoists. |
Not suitable for: Continuous lifts >600 kg (1.05 kW motor insufficient, risk of thermal overload). Construction sites without stable 230V single-phase power (requires external generator). Undersized chains for very heavy materials (Ø4.5 mm chain is the limit for 600 kg with pulley). Lifts in permanently high humidity environments (IP 54 protection is auxiliary — prefer IP 65 for frequent immersion).

Frequently asked questions
How long does it take for the hoist to lift 300 kg up to 11 meters?
A speed of 8 m/min at 300 kg load (without pulley) allows lifting 11 m in: 11 m ÷ 8 m/min = approximately 1 minute and 22 seconds. However, check initial acceleration — the very first few seconds might be slightly slower before motor stabilization.
If I use the pulley, do I lose speed and height?
Yes. The pulley doubles the capacity (300 → 600 kg) but halves the speed (8 → 4 m/min) and height (11 → 5.5 m) because the chain multiplies into 2 sections. This is a necessary trade-off: to lift 600 kg with a 1.05 kW motor, you must sacrifice speed and height. If speed is needed at 600 kg, a more powerful motor is required.
How do I mount the pulley?
Procedure: (1) Securely lock the chain. (2) Thread the pulley onto the chain between the two hooks (one for load, one for pulley). (3) Tighten the bolts of the pulley bracket to the beam. (4) Check chain alignment (not twisted). This operation takes about 15 minutes, carefully. If in doubt, entrust it to a specialized technician for safety checks.
Does the automatic brake work if there's a power outage?
Yes, that is its purpose. If there's a sudden power interruption, the integrated spring brake mechanically locks the chain, and the load remains suspended. This provides very high protection against falls. However, if power is out for >5 minutes, you won't be able to lower the load — an external generator or a technician for manual brake release will be required.
Can I use the hoist on a wooden beam?
Not recommended. The mounting bracket is designed for steel I-beams or tubular profiles that distribute the load evenly. Wood risks localized splitting under the bolt. If it's a wooden beam, entrust it to a builder for structural static checks — an steel distribution plate might be needed under the bolt.
What current does it draw during operation?
The 1.05 kW motor at 230V single-phase draws approximately 5–6 A at full load (standard 300 kg, 4–5 A during light operation). A standard 10 A single-phase meter is sufficient. However, if other 230V tools are operating simultaneously (brush cutter, grinder), there's a risk of overload — prefer a dedicated circuit.
How often should I service the automatic brake?
Annual service is recommended. Entrust it to an authorized Güde technician for a brake test (verify 600 kg load blockage for 10 minutes). Cost ~€80–120 for service. If the hoist is used frequently (>100 cycles/month), consider semi-annual service.
Is the Ø4.5 mm chain strong enough for 600 kg?
Yes, if the pulley is installed correctly. The Ø4.5 steel chain has a breaking strength >600 kg (standard 4:1 safety margin). However, integrity depends on: lubrication maintenance, absence of rust, no visible mechanical damage. Inspect the chain monthly for cracks and corrosion.
Can I lift 500 kg (between 300 and 600)?
Yes. Without pulley: the motor can lift up to 300 kg at 8 m/min (capacity limit). With pulley: the motor can lift 300–600 kg at 4 m/min by varying the speed. At 500 kg with pulley, speed will be ~4.8 m/min (interpolation). However, do not set a load >300 kg without the pulley — risk of motor overload.
