General information

DoLast lifting clamps are the solution for the transport of sheets and profiles and can be tailored precisely to your area of application. The use of clamps and grabbers is subject to the provisions of BGR 500 (formerly UVV 18.4). To transport vertically hanging sheets, clamps with safety levers must be used. To erect lying plates and for laying down and turning them, there are suitable turn clamps. The drag on the clamp used as lifting system presses the hardened clamp jaw (pawl) with its grooves against the sheet so that a kind of micro form fit occurs. On the opposite side, a rosette presses into the sheet in the same way which should have a surface hardness between St 37 and St 52.3. An internal spring ensures that the lifting clamp holds also when putting down the sheet, i.e. without lifting force. Only by loosening the safety lever, the sheet is released. The clamp effect through the lifting system is only sufficient if the thickenss of the sheet is in the clamp’s lever area. With a clamp with a lower grasper threshold of, for instance, 10 mm, too thin sheets of, for instance, 7 mm would slip through. Clamps for vertical transportation of sheets or plates are always suitable for transporting individual parts only. For horizontal sheet transport, there are lockable and non-lockable clamps. For thin sheets, which can bend and vibrate very strongly, the lockable models are recommended. In order to safely transport sheets or sheet packets horizontally, it is better to use DoLast lifting beams and 4 clamps. For dry and polished sheets, special clamps are available which have a higher pressure with even, non-corrugated pressing surfaces to avoid grooves in the sheet. For special profiles, such as rails, sheet piles or doubleT beams, there are special clamps which partly also work by form fitting or blocking. Distance-operated clamping is possible through compressed air or mechanically. This is especially suitable for clamp lifting beams, as the lifter – standing outside of the danger area – can trigger all clamps at the same time. For use with chemicals and for temperatures above 50° C, standard clamps are not suitable.The lever joints would soon be damaged. Special clamps are available to use with chemicals. Please enquire. Due to different designs of the clamps, always observe the instructions of use supplied with the respective clamp model. As a rule, only use clamps with legible labels for carrying capacity, grabbing area and type plate. Notes on operation: The surfaces for the clamps on the transport goods must be right opposite of one another. The surfaces should be free from scale, dirt, lubricants or other covers. For vertical lifting with suitable clamps, only a part may be transported. When erecting and turning with two or more lift clamps, the edge lying at the bottom must remain in contact with the floor.To prevent the load from swinging, it is lifted above the centre of gravity or preferably, two clamps are used. No persons should be located under hanging loads and in the danger area. Every clamp must be inspected before every commissioning and after any repairs as well as at least once a year by an expert. If used regularly, an inspection interval of no more than 3 months is recommended. The bolts, the housing, the suspension and levers must be checked for deformation and cracks. The grabbing parts must be replaced if they are visibly worn out. Here, every tooth must be checked because if the sheet thickness remains the same, only one tooth wears out. During inspection, the spring tension must also be checked. Worn out parts should be replaced by Dolezych. Only original spare parts guarantee the clamps’ functionality.

Lifting clamp Do 80 with safety stop

Do 80 is available up to a carrying capacity of 30.000 kg. Lifting clamps with greater carrying capacity and larger grab range on request. The surface hardness of the transport good must not exceed HRC 37.

Do 81 lifting clamps with swivel eye and safety stop

Do 81 is available up to a carrying capacity of 30.000 kg. Lifting clamps with greater carrying capacity and larger grab range on request.

Do 24/K lifting clamp for sheet piles with remote unlocking

The safety clamp for sheet piles is suitable to turn sheet piles by 90°. It has remote unlocking which means that the lifting clamp can be unlocked in height using a cable winch.  

Lifting clamp Do 81/T with swivel eye

Lifting clamp Do 88 Do with position screw

Vertical turning and lifting clamp, can be locked in closed position. Suitable for lifting and 90° turning of surfacesensitive materials (stainless steel, plastic, chipboard, etc.). The specially coated grab jaws can be adjusted continuously with a position screw.     

Do 80 G Lifting clamps with smooth grab plate

Lifting clamp and smooth, large pressing plate for sheets with sensitive surface for vertical transport and for turning by 90°.This lifting clamp has a high pressing force and works by force-fit. The clamping force is designed for a minimum friction factor of 0.25 µ with double safety. From a carrying capacity of 2,500 kg on, the grab range can be adjusted with a position screw to increase the pressure. The surfaces of the sheets to be transported must be dry, clean and free from lubricants.

*) with pre-adjustment

**) for wood and chipboard

Do 86 MPS lifting clamps with rigid suspension eye

MPS 1 model For vertical lifting and 180° turning of sheet, steel plates, beams and steel construction elements. The safety lever to open the clamp can be locked in closed position with a lifted load. Unsupervised opening of the clamp when unloading is therefore prevented.

 MPS 2 model Function and area of application as with model MPS 1, but the safety lever to open the clamp can be locked in open and closed position.This means that the clamp can be brought to the load in open position, fitted and locked. After dropping and securing the load, the “openly” locked clamp can be lifted with the crane.

Do 87 MPC lifting clamps with swiveling suspension eye

MPC 1 model For vertical lifting 180° turning and lateral lifting of sheet, steel plates, beams and steel construction elements. The safety lever to open the clamp can be locked in closed position with a lifted load. Unsupervised opening of the clamp when unloading is therefore prevented.

 MPC 2 model Function and area of application as with model MPC 2, but the safety lever to open the clamp can be locked in open and closed position.This means that the clamp can be brought to the load in open position, fitted and locked. After dropping and securing the load, the “openly” locked clamp can be lifted with the crane.

Horizontal lifting clamps

When transporting with only 2 clamps, there is a risk of the load swinging. It is not allowed to be present under transport goods of clamps and grabbers.

NOTE! For horizontal lifting clamps, the carrying capacity is reduced in accordance with the angle of inclination of the lifting gear.

Horizontal lifting clamp Do 90 FHX

Horizontal lifting clamps for the transport of form-stable sheets, sheet parcels, steel plates. The lever clamps are fitted to suitable lifting suspensions – which we can supply on request – and attached in three or preferably four points

DoLast lifting clamp by Dolezych

Do 83 lifting clamp with simple opener

The lifting clamp lifts objects which fit into grab range. Fast, simple and safe. The large grab range allows usage for the most varied transport tasks in steel and machine construction for charging tool machines and construction installations as well as for welding and installing all kinds of components. Due to the spring tension of the clamp jaws, the transport goods are also held if the lifting gear is released. Lifting clamps up to 2.0 t carrying capacity are equipped with round element chains and the grabbers with higher carrying capacity with roll chains (fleyer chains).

Also available with protective coating for a surcharge.
