A low clearance manual hoist is a lifting equipment designed specifically for space constrained environments. Its core features are reflected in structural optimization, functional adaptation, and operational flexibility. The following is a specific analysis:

1、 Compact structure

Ultra low clearance design: The low clearance manual hoist significantly reduces the height of the machine body by shortening the distance between the lower hook and the crossbeam, reducing clearance occupancy by 30% to 50% compared to traditional models. For example, the YTG series low clearance hoist has a minimum clearance size of 166mm (1 ton load), allowing it to be flexibly deployed in height restricted areas such as low rise factories and tunnels.

Modular combination: Adopting a foldable handle, telescopic chain box or split design, the volume can be further compressed in non working state, reducing the occupation of lateral space. This design is particularly suitable for temporary factory buildings or work scenarios that require frequent movement.

2、 Functional adaptability

High strength core components:

Crane Chain: High strength alloy steel chains are selected, with diameters and chain numbers matching different load requirements (such as 5.0 × 2 chains for 1 ton load and 10 × 8 chains for 20 ton load), ensuring a safety factor of ≥ 4 times.

Forging hook: The hook is strengthened by forging technology, and the opening change rate is controlled within 15%. The resistance to bending and twisting is improved by 50%, making it suitable for complex working conditions.

Multi level load and stroke customization:

We offer load options ranging from 1 ton to 20 tons, with standard lifting heights covering 2.5 meters to 3.5 meters, and support customization of larger tonnage or higher stroke according to customer needs. For example, a certain model of hoist can be expanded to carry loads of 4 tons and 6 tons, meeting the lifting requirements of heavy equipment.

The chain length is strictly matched with the lifting height to avoid the risk of repeated operations or exceeding the limit due to insufficient travel.

3、 Operational flexibility

Track and width adaptation:

By using accessories such as spacers and washers, the hoist can be compatible with different track widths ranging from 75mm to 190mm. The adjustable flange width design further enhances its versatility.

The wheel set equipped with deep groove ball bearings ensures smooth operation on the track, reduces friction resistance by 30%, and makes operation more effortless.

Ergonomic optimization:

The handle design conforms to ergonomics, providing comfortable and effortless grip. The single operation force can be reduced to 25kg (under a load of 1 ton), reducing operational fatigue.

Support single speed or dual speed lifting mode, users can choose the appropriate operating rhythm according to their job accuracy requirements.

4、 Safety and reliability

Multiple braking protection:

The mechanical ratchet pawl brake works in conjunction with the overload protection clutch, with a braking distance of ≤ 200mm (1.25 times overload test), ensuring reliable stopping of the load in emergency situations.

Brake pad thickness monitoring and automatic compensation function extend the service life of the braking system.

Anti disconnection and limit design:

The gap between the chain plate and the chain should be controlled within 3mm to prevent the chain from derailing; The travel limit switch automatically shuts off when there are still 2 turns left in the chain, avoiding the risk of overtravel.

The final pin of the chain adopts an anti loosening design, and an automatic warning is issued when the wear of the pin diameter exceeds 5%.

5、 Environmental adaptability

Corrosion resistance and dust prevention:

The shell of the gourd is treated with galvanizing or spray coating, and key components such as gears and sprockets can be upgraded to 316L stainless steel material to adapt to high humidity or corrosive environments.

The protection level reaches IP54 and can be equipped with a positive pressure dust cover. It can still operate stably in places with high dust concentration, such as mines and metallurgy.

Wide temperature range operation:

In low-temperature environments (below -20 ℃), equipped with low-temperature steel chains and preheating devices to ensure material toughness; In high temperature environments (≥ 60 ℃), high-temperature resistant lubricating grease and enhanced heat dissipation design are used.
