Key takeaway: Choosing an elevator installation hoist is not about picking "the machine that lifts the most" — it’s about selecting a safe, efficient installation process system that fits your shaft.
Traditional elevator installation relies on scaffolding: 3–5 days to erect and dismantle, heavy material handling, high-risk work inside the shaft — and you still can’t install the car until the scaffold is gone. That’s why leading elevator installation companies worldwide have been shifting to scaffoldless installation technology, built around a cable climber and an installation work platform (False Car).
But hoists on the market vary widely, with prices ranging from a few thousand to tens of thousands of dollars. How do you choose without falling into traps? Work through the 8 points below and you’ll rarely go wrong.
This is the question you must answer before anything else. It determines the load capacity, speed, and cost of the whole system.
2:1 process: The wire rope is reeved through a movable pulley for a 2:1 mechanical advantage — higher load capacity (typically 1,000 kg class), ideal for heavy guide rail installation and high-volume work. The trade-off: the steel wire rope is about twice the shaft height in length.
1:1 process: The wire rope is suspended directly — lighter, more flexible platform (typically 400 kg class), ideal for low- and mid-rise, light-duty work. Wire rope length is roughly the shaft height.
Advanced option: For high-volume projects chasing maximum efficiency, there is the "car-as-platform" method — use the new elevator car itself as the work platform, driven by climbers, with a load capacity up to 4,000 kg in a 2:1 configuration. No platform assembly/disassembly — the car goes straight into service.
The rule is simple: check your shaft height, guide rail weight, and daily installation volume first — then decide the process. Choose wrong here and everything downstream is wrong.
Many buyers only read the nameplate "rated load 1,000 kg". But remember: actual usable load = rated load − platform self-weight − climber weight − tool weight.
Take a typical configuration: a steel platform rated 1,000 kg with a self-weight of 390 kg (note: spec sheets usually list self-weight excluding the lifting device). That leaves about 600 kg of margin; after adding the climber (about 70 kg) and tools on site, you have roughly 500 kg of actual carrying capacity. All-aluminum platforms can weigh as little as the 150 kg class — meaning much more "payload" at the same rated load. The lighter the platform, the more valuable the same rated load — which is why leading manufacturers keep pushing aluminum lightweight design.
An accident in a shaft is a serious matter. A qualified hoist must have two independent safety systems:
1. Overspeed fall arrester: automatically locks the platform when descent speed exceeds the set value (e.g., 30 m/min), with a locking distance ≤ 200 mm, working with high-strength steel wire rope (e.g., Φ10.2 / Φ11.5).
2. Safety tong: automatically clamps and locks when the wire rope loses tension — the second line of defense.
When evaluating, check three numbers: triggering speed, locking distance, and the arrester’s rated load. The more sensitive the trigger and the shorter the locking distance, the better. The best industry configurations use "fall arrester + safety tong" as a dual guarantee — if either one fails, the other catches you.
The climber is the "heart" of the entire system:
Lifting speed: typically 6–18 m/min; multi-speed options are more practical (e.g., 9/18 dual-speed — slow for alignment, fast for lifting)
Motor quality: prefer German-brand motors, with customizable voltage/frequency
Protection rating: shafts are dusty and damp — at least IP55 with built-in thermal protection (e.g., TW)
Load limiting: a built-in mechanical load-limiting system that protects against overloading and rough operation
Steel platform: high strength, high load — suited to the 2:1 heavy-duty process, but heavier (approx. 390–460 kg)
Aluminum platform: light (approx. 150–200 kg), easier to handle and install — suited to the 1:1 process; all-aluminum platforms can stay under 200 kg
Rule of thumb: every 100 kg saved on platform weight is a leap in on-site handling and installation efficiency. Choose aluminum when the budget allows.
Guide rail spacing differs from project to project (1,200–3,000 mm is common). Your platform must adapt to different rail spacing — otherwise you need a new platform per project and costs explode.
Check: does the product series cover the full 1,200–3,000 mm range? Can individual platforms be bidirectionally adjusted within their specified range (e.g., 1,500–2,100 mm, 1,700–3,000 mm options)? Is adjustment quick — the best designs adapt to a new project in minutes.
Scaffoldless installation is never just one hoist — it’s a full tool system:
MiniHoist (rail lifting hoist): dedicated tool for lifting guide rails in the shaft — look for wireless remote control, wire rope anti-detachment protection, and an optional single-phase power supply (handy for on-site temporary power)
Expansion beam: replaces top-floor pre-embedded anchors, reusable, with sufficient extension range (e.g., 1.5–3 m)
Diverter pulley, balance weight, rope winding device: keep the 2:1 wire rope from tangling (choose a diverter pulley compliant with EN1808)
Transport box: 2T/4T steel boxes for convenient tool management and safe long-distance transport
The completeness of the tool chain determines whether you finish in 1 day on site — or spend 3 days hunting for parts.
Look for TÜV / SGS international certification on the complete machine and safety components
Check whether the supplier participated in drafting national standards (e.g., GB40160-2021, GB19155-2017) — companies that help write the standards are usually at the top of the industry domestically
Safety components (fall arresters) need separate certification — these are life-saving parts
Equipment is a durable asset; service is a long-term account. Check three things:
3. Production scale: factory area and smart production lines (e.g., a 25,000 m² intelligent manufacturing base)
4. Export track record: experience serving demanding Western markets (USA, Germany, Spain, Brazil, etc.) — overseas reputation is the most honest reference
5. Customization capability: different elevator OEMs have different car structures — can adapters and mounting brackets be customized? If the supplier can’t customize, you’ll hit a wall as soon as projects diversify.
❌ Price-only comparison: equipment 30% cheaper usually means a class lower in safety and a heavier platform
❌ Rated-load-only thinking: without deducting platform self-weight, the number is fiction
❌ Ignoring process matching: mixing up 1:1 and 2:1 means buying something you can’t use
❌ Skipping accessories: main unit without the tool chain = stuck on site
❌ Not asking for certifications: a fall arrester without TÜV/SGS is unacceptable at any price
In one sentence: Choosing an elevator installation hoist = choosing the process (1:1 / 2:1 / car-as-platform) + dual safety + power core + platform (weight & adaptability) + tool chain + supplier (certification, experience, customization). Check all six and your purchasing decision won’t go wrong.
