Pneumatic Winch with Air Motor 50-2000kg Explosion-Proof Site | KLD

A compact pneumatic winch driven by compressed air, intended for environments without electricity or with flammable and explosive atmospheres. It uses a high-speed air motor with adjustable speed, a pneumatic clutch for gravity release, and an independent pneumatic brake. Pulling force from 50 kg to 2000 kg is customized to the application.

Quick Specs

Power source: compressed air   |  Rated pull: 50–2000 kg (customized)
Rope length: typically 100 m   |  Speed: made to order

Application Scenarios and Applicable Boundaries

- No-power sites — the winch runs on compressed air instead of electricity.
- Flammable and explosive atmospheres — as the machine carries no electrical components, it is suited to sites with explosion-protection requirements (the applicable zone classification must be confirmed on site).
- Sites with an existing compressed-air supply — intended for dedicated locations equipped with compressed air.
- Compact installations — small size and light weight suit confined or movable working positions.

Boundary: this is a made-to-order product. Ratings, rope length and speed are engineered to the customer's requirement and confirmed by drawing; the values above are the customization range, not a fixed catalogue rating. It is not intended for personnel lifting. Explosion-protection applicability must be assessed against the site's hazardous-area classification and the compressed-air quality/supply available.

Features Benefits

Adjustable speed — the high-speed air motor allows rope speed to be adjusted for different stages of the working cycle.
Gravity release — the pneumatic clutch allows the load to be released without motor power, for lowering or free-payout operations.
Braking — an independent pneumatic brake provides holding and stopping function separately from the drive.

Complete Technical Specifications

Size Installation and System Interface

Outline dimensions: engineered per application (made-to-order product; dimensions are confirmed by drawing).
Mounting: base-frame fixing with mounting holes; installation position and rope exit direction agreed per site.
Pneumatic interface: compressed-air supply required on site; air line and control valve arrangement to be confirmed with our engineers.
Rope interface: drum with rope fixed as agreed (grooved drum optional).

Control Safety and Protection

- Independent pneumatic brake, separate from the drive, for holding and stopping.
- Pneumatic clutch enables gravity release for lowering / free payout without motor power.
- Adjustable speed via the air motor (controlled by the air supply / control valve).
- No electrical components on the machine — reduces ignition risk in flammable or explosive atmospheres, subject to site zone classification.
- Optional control & safety items: limit switch, encoder with main-shaft limit switch, slack-rope switch, rope follower, grooved drum.
- Personnel lifting is excluded.

Customization Options and Engineering Process

Configured around your operating conditions — Share the required line pull, rope travel, operating speed, duty cycle, power supply, installation envelope and environment. KLD will review the application and provide a proposed configuration, technical drawing and quotation for approval. Free design schematics are provided for different scenarios.

Standards Testing and Quality

The company operates an ISO 9001 quality management system. CE conformity documents (LVD, EMC) are available for applicable configurations on request.

Factory testing follows the approved technical specification for each configured unit and may include: no-load run, rated-load operation, brake function, positioning accuracy, limit function and PLC control verification. Available documentation may include design drawings, electrical diagrams, inspection records and functional test results, depending on project scope.

Engineering Cases

As this model is made to order, no fixed reference case is published. Typical applications include material handling and pulling duties at petrochemical, mining, marine and other sites where electrical power is unavailable or where flammable/explosive atmospheres are present and compressed air is available. Please contact us with your load, rope length, speed and site conditions, and we will provide a solution and design drawing.
