LTD200, LTD50-100, MH40, MH50, And MT50 — Traction Hoist Model Comparison For Elevator Installation

What Is the Wuxi Rigid Traction Hoist Family?

The Wuxi Rigid traction hoist family is a range of electric traction hoists designed specifically for elevator installation and modernization, spanning material-only lifts to high-rise passenger car installations. Each model in the family shares common design principles — gear-driven traction sheave, dual independent brakes, calibrated overspeed safety lock integration — but is sized to a different capacity and duty range.

Model	Primary use	Rated capacity	Typical shaft height
LTD200	Heavy-duty installation	2000 kg	Up to 150 m
LTD50-100	Mid-duty installation	1000 kg	Up to 80 m
MH40	Compact material lift	400 kg	Up to 40 m
MH50	Compact material lift	500 kg	Up to 40 m
MT50	Material lift, single-function	500 kg	Up to 30 m

The family shares common accessories — adapter plates, overspeed safety locks (OSL30 / OSL50 / OSL70), diverter pulleys, wire ropes, and transport boxes — which simplifies spare parts and operator training across a mixed fleet.

Different voltage variants (220 V, 415 V, 480 V) are available for each model on request. Wuxi Rigid provides multi-voltage motor options for export projects.

When Is the LTD200 the Correct Choice?

The LTD200 is the correct choice when the rated load exceeds 1000 kg, the shaft height exceeds 80 m, or the installation must lift car and counterweight simultaneously. It is Wuxi Rigid's flagship heavy-duty installation hoist.

Typical LTD200 applications:

Passenger elevator installations with car + counterweight lift in a single hoist run.

Heavy-duty freight elevator installations where the car weight exceeds 1500 kg.

High-rise installations where the shaft height exceeds 80 m and the additional rope capacity is needed.

Modernization projects where the existing shaft requires a hoist with a high single-lift capacity.

The LTD200's 480 mm traction sheave and 11–15 kW motor deliver the speed and capacity to handle the heaviest installation lifts. The dual independent brakes and overspeed safety lock integration meet the personnel-lift standard requirements.

When Is the LTD50-100 the Correct Choice?

The LTD50-100 is the correct choice when the rated load is in the 800–1000 kg range, the shaft height is under 80 m, and the typical installation is a passenger elevator in a mid-rise building. It is the workhorse of the Wuxi Rigid family for typical Chinese and international mid-rise projects.

Typical LTD50-100 applications:

Standard passenger elevator installations up to 1000 kg rated load.

Mid-rise residential and commercial installations up to 80 m shaft height.

Modernization projects where the existing shaft can accommodate a 1000 kg capacity.

Mixed-use installations where the hoist will be redeployed after the initial project.

The LTD50-100's 400 mm traction sheave and 5.5–7.5 kW motor deliver the speed and capacity for typical mid-rise work. The unit's compact size allows it to be installed in shafts with limited pit depth or headroom.

When Is the MH40 the Correct Choice?

The MH40 is the correct choice for material-only lifts in tight shafts, with a rated capacity of 400 kg and a compact footprint. It is the smallest traction hoist in the family, designed for tools, rail sections, and small components — not for personnel lifts.

Typical MH40 applications:

Material-only lifts in shafts that cannot accommodate a larger hoist.

Tool and component lifts between floors during elevator installation.

Modernization projects where the existing shaft is too narrow for a larger unit.

Temporary lifts during construction, removed once the permanent elevator is operational.

The MH40 is not designed for personnel lifts; using it for personnel work requires additional safety equipment (e.g., a Safety Lock) and is generally not the standard practice.

When Is the MH50 the Correct Choice?

The MH50 is the correct choice for material-only lifts with a slightly higher capacity than the MH40, in shafts that can accommodate its slightly larger envelope. It is the mid-compact material hoist of the family.

Typical MH50 applications:

Material lifts requiring up to 500 kg capacity.

Mid-rise installations where a personnel lift is supplied separately.

Component lifts for rail sections, door equipment, and machine beams.

Construction lifts during the structural phase, before the permanent elevator is installed.

Like the MH40, the MH50 is designed for material lifts and is not the standard choice for personnel-carrying duty.

When Is the MT50 the Correct Choice?

The MT50 is the correct choice for single-function material lifts where simplicity, low cost, and ease of deployment are the primary requirements. It is the most basic traction hoist in the family, with a simplified control system and a smaller traction sheave.

Typical MT50 applications:

Single-function material lifts in low-rise construction.

Tool lifts in shaft modernization where the permanent elevator is being replaced.

Temporary construction lifts removed at project handover.

Repetitive lifts of identical components (e.g., door operators) during a phased installation.

The MT50's simplified control system reduces the upfront cost and the operator training requirement. The trade-off is that it lacks the variable-speed control of the LTD200 and LTD50-100, so it is not suited to installations requiring smooth starts and stops.

How Are the Models Compared on Key Dimensions?

The five models cluster into three groups: heavy-duty (LTD200), mid-duty (LTD50-100), and compact material (MH40 / MH50 / MT50). The grouping simplifies fleet planning and operator training.

Group	Models	Capacity range	Shaft height	Personnel lift
Heavy-duty	LTD200	2000 kg	Up to 150 m	Yes
Mid-duty	LTD50-100	1000 kg	Up to 80 m	Yes (with overspeed safety lock)
Compact material	MH40 / MH50 / MT50	400–500 kg	Up to 40 m	No (material only)

A mixed fleet of one heavy-duty and one mid-duty hoist covers most elevator installation projects; adding one or two compact material hoists covers the tool-lift and component-lift requirements.

What Standards Apply to Each Model?

The standards depend on the duty and the destination country; Wuxi Rigid provides certificates matched to the destination standard. Standard coverage:

Standard	Region	Applies to	Wuxi Rigid certificate
EN 81-20 / EN 1808	EU	LTD200, LTD50-100 (personnel lift)	CE marking
ASME A17.1 / ANSI A10.28	USA	LTD200, LTD50-100 (personnel lift)	Certificate on request
GB 7588 / GB 19154	China	All models	Standard certificate
AS 1418.10	Australia	LTD200, LTD50-100	Certificate on request

The MH40, MH50, and MT50 are typically supplied with material-lift certifications only; converting them to personnel lifts requires additional safety equipment and is generally not Wuxi Rigid's standard offering.

What Are the Power and Electrical Requirements?

All five models require 3-phase power at the destination voltage; single-phase operation is not available. Multi-voltage motor options are available for export projects.

Region	Standard voltage	Frequency	Wuxi Rigid option
China	380 V	50 Hz	Standard
EU	400 V	50 Hz	Multi-voltage motor
USA	480 V	60 Hz	Multi-voltage motor
Australia	415 V	50 Hz	Multi-voltage motor
Site generator	380–415 V	50 / 60 Hz	Custom configuration

The starting current of the larger motors (LTD200, LTD50-100) requires a site supply with adequate capacity; the smaller motors (MH40, MH50, MT50) can be operated from smaller generators.

What Are the Common Selection Errors?

Five errors recur when matching the model to the project.

Undersizing. Choosing a smaller model to save cost, leaving no margin for the heaviest single lift. The hoist operates at its limit and brake wear accelerates.

Oversizing. Choosing a larger model with more capacity than needed, increasing cost and the equipment footprint unnecessarily.

Wrong voltage. Selecting a 380 V model for a 480 V site, or a 50 Hz model for a 60 Hz grid. The motor runs hot or stalls.

Using a material hoist for personnel. Using an MH40 / MH50 / MT50 for personnel lifts without the additional safety equipment. Fails the personnel-lift standard.

Ignoring the duty cycle. Selecting the lightest motor that meets the headline speed, ignoring the sustained climb duration. The motor overheats.

Each error is preventable by reviewing the duty cycle, the personnel-lift requirement, and the site's electrical supply before ordering.

How Does Wuxi Rigid Support Model Selection?

Wuxi Rigid supports model selection with the LTD200, LTD50-100, MH40, MH50, and MT50 data sheets and a sizing questionnaire. The questionnaire covers load, speed, shaft height, duty cycle, voltage, and standard.

Procurement teams should provide:

Rated load (kg) and the heaviest single lift (kg).

Shaft height (m) and the planned number of stops.

Lifting speed (m/min) and the duty cycle (cycles per hour).

Power supply (V / Hz / phase) and the available fault current.

Destination country and applicable standard.

Required certificates (CE, GB, ASME, etc.).

Wuxi Rigid returns a recommended model, a complete specification sheet, and a quote including the Steel Transportation Box for shipping.

What Accessories Should Be Ordered with Each Hoist?

Each hoist ships with the standard accessories, but several complementary items should be ordered with the initial purchase to avoid delays during deployment. Recommended accessories:

Overspeed safety lock (OSL30 / OSL50 / OSL70) for personnel lifts.

Adapter plates matched to the project's rail profile.

Diverter pulley for double-wrap roping.

Steel wire rope for traction hoist of the correct diameter and length.

Steel Transportation Box for shipping and on-site storage.

Spare parts kit (brake linings, contactors, fuses, rope terminations).

The full accessory list with part numbers is in the Wuxi Rigid catalogue.

Frequently Asked Questions

Q: Can the LTD200 be used as a permanent elevator hoist after installation?

A: The LTD200 is engineered for installation duty, with a high duty-cycle rating and an overspeed safety lock for personnel lifts. It can be repurposed as a permanent hoist in some jurisdictions, but the elevator's permanent certification typically requires a permanent-duty hoist. Confirm with the elevator manufacturer before repurposing.

Q: What is the difference between the MH50 and the MT50?

A: The MH50 is a general-purpose compact material hoist with a 500 kg capacity and a standard control system. The MT50 is a single-function material hoist with a simplified control system, a smaller traction sheave, and a lower cost. The MT50 trades variable-speed control for simplicity and cost.

Q: Can the MH40 be converted to a personnel lift?

A: The MH40 is not designed for personnel lifts as standard. Converting it would require an overspeed safety lock, an enclosure or guard, and additional operator controls. The cost of the conversion typically exceeds the cost of selecting the LTD50-100 from the start.

Q: What rope diameter is correct for each model?

A: Standard rope diameters are 16 mm for the LTD200, 13 mm for the LTD50-100, and 10 mm for the MH40 / MH50 / MT50. Wuxi Rigid supplies each hoist with a recommended rope specification; using a different diameter may affect traction and rope life.

Q: Can the LTD200 operate on a 60 Hz power supply?

A: Yes, the LTD200 is available with a 60 Hz motor option for the US and other 60 Hz markets. The multi-voltage motor is factory-configured to the destination voltage; field reconfiguration is not supported.

Q: How is the model matched to the shaft height?

A: The shaft height sets the required rope length (typically 2× shaft height for 1:1 roping or 4× shaft height for 2:1 roping). Wuxi Rigid supplies each hoist with rope lengths matched to the project's shaft height. Longer shafts may require a rope-reel option.

Q: Can the MH40, MH50, or MT50 be used on a single-phase power supply?

A: No, all Wuxi Rigid traction hoists require 3-phase power. Single-phase operation is not available. For sites without 3-phase power, a phase converter or a small generator is required.

Q: What is the warranty on each model?

A: Standard warranty is 12 months from commissioning or 18 months from delivery, whichever comes first. Extended warranty and service contracts are available on request.
