Choosing a Hydraulic Claw Jack: Application Fit and Specification Checks

Step 1: Define your lifting requirement

Gather these facts about the job before you look at models:

• Load weight and where it will be lifted. Will the jack lift from under the load on the top saddle, or from a low ledge or edge using the claw?
• Available clearance. Measure the gap under the lifting point. If you plan to use the claw, measure the height of the edge you will lift from.
• Required rise. Work out how far the load has to go up, for example to fit skates, packing or rollers.
• Floor or support surface. Check the space available for the jack base and whether the surface can carry the load through the base.
• Handling. Consider whether one person needs to carry and position the jack.

Step 2: Compare the listed models

The published table lists five models. Each has two capacity values: one for the top lifting point and a lower one for the claw.

Step 3: Apply the selection criteria

Capacity at the lifting point you will actually use

On every listed model, the claw capacity is half the top capacity. For example, the MHC-10 is listed at 20 t on the top and 10 t on the claw. If the job needs the claw, choose by the claw rating, not the top rating. Leave a margin for any uncertainty about the load weight or how it is distributed. Confirm with the supplier how much margin is appropriate.

Claw height against the available edge

The listed claw heights go from 16 mm (MHC-2.5) to 35 mm (MHC-25). Higher-capacity models have a higher claw. For very low-clearance lifts, check that the claw will fit under the load at the capacity you need.

Minimum height and lifting height

Minimum height runs from 247 mm to 360 mm. Use it to check whether the jack body fits beside or under the load. Lifting height does not rise steadily with capacity. The MHC-10 is listed at 165 mm, the MHC-5, MHC-15 and MHC-25 at 155 mm, and the MHC-2.5 at 124 mm. Compare these values with the rise you need.

Base size and support surface

Base footprints go from 215×125 mm to 395×295 mm. Make sure there is room for the base and that the surface beneath can carry the load.

Weight and handling

Net weights range from 8.8 kg (MHC-2.5) to 74.5 kg (MHC-25). Heavier models may need more than one person or handling equipment to move and position them. Each unit is listed with a packing quantity of one piece.

Example application fit

• Light machinery lifted by the claw from a low edge: the MHC-2.5 has the lowest listed claw height (16 mm) and weight, with a claw capacity of 2.5 t.
• Medium loads where extra rise helps: the MHC-10 has the highest listed lifting height (165 mm) and a claw capacity of 10 t.
• Heavier equipment: the MHC-15 and MHC-25 are listed at 15 t and 25 t on the claw. They have taller claws and larger bases.

These are only starting points. Base the final choice on your measured load, clearance and rise.

When this product may not fit

• The claw edge on the load is lower than the listed claw height of the model with the capacity you need.
• The load on the claw is more than 25 t, or the load on the top is more than 50 t, which are the highest values listed.
• The required rise is greater than the listed lifting height.
• The clearance beside or under the load is less than the model's minimum height or base size.

Information to confirm before ordering

The product listing does not give pricing, lead time, certifications, compliance with standards in your market, warranty terms, operating instructions or safety limits. Before you buy, ask Hebei Dawei Hoisting Machinery Manufacturing Co., LTD for these details and for the operating manual. Have your team check that the selected model meets the safety rules that apply at your site.
