I. LD3.2-16t European single beam bridge crane standardization design
Innovation:
1. The hoisting mechanism and the hoist operating mechanism adopt the European-style electric hoist to use the box-shaped main beam section.
2. The main beam adopts European-style optimization design, and adopts box-shaped beam or H-beam structure welded by steel plate, which has light weight and reasonable structure.
3. The end beam is welded by rectangular tube or steel plate, and the formed end beam is processed once in the numerical control boring machine.
4. The cart drive unit adopts a hard-toothed three-in-one drive unit.
5, hoist strokes make full use of the span distance of the cart to maximize the use of the requirements.
Second, LH5-50t European-style bridge crane
Innovation:
1. The crane trolley is designed with the design concept of European structure, which makes the structure more compact and the appearance is more beautiful.
2. The main beam adopts the European structure optimization design. It adopts the off-rail box beam welded by steel plate and is used with the square steel track. It has light weight and reasonable structure.
3. The end beam is welded by rectangular tube or steel plate, and the formed end beam is processed once in the numerical control boring machine.
4. The cart drive unit adopts a hard-toothed three-in-one drive unit.
5, the whole vehicle frequency conversion control.
Third, the development of a new curved rail conveyor system
Innovation:
1. Adopt advanced and mature design and processing technology, adopt box-shaped beam curved rail structure, and the lower flange plate of curved section is made of profiled cutting steel plate. High quality lifting device.
2. The development and design of the entire new curved rail conveyor system system must comply with the crane design specification GB 3811.
3. The new curved rail conveying device system adopts the design of new box type rail and drum type wheel, which makes the lifting device run more smoothly in the curved section and the straight section of the track, the wear state is obviously improved, and the service life of the rail is obviously improved.
4. In order to reduce the wear of the track curve part, the straight line segment and the curve segment radius of the track are ≥800mm.
Fourth, the new combined single main beam crane
Innovation:
1. The design of the main beam is designed by using modular units;
2. The pins and bolts are connected between each module unit;
3. The whole machine is shipped in bulk, and the whole machine is assembled on site;
4. Reserve stocks can be kept.
5. New combined double girder crane
Innovation:
1. The main beam adopts the combined modular truss unit and the second modular truss unit is made up of rectangular tube, square tube, channel steel, angle steel, H-shaped steel, welded steel pipe, I-beam or round steel.
2. The connection of the main beam of the modular unit is connected by a positioning pin shaft and a bolt set.
3. The end beam is welded by rectangular tube or steel plate, and the formed end beam is processed once in the numerical control boring machine.
4. The cart drive unit adopts a hard-toothed three-in-one drive unit.
5. The running track adopts a square steel track, and the track is also connected by a combined type through a joint.
Sixth, the main and auxiliary hook running electric hoist products
Innovation:
1. The new hoist hanger can be installed together with two hoists, and two hoists share a sports car.
2. The main and auxiliary hook-operated electric hoist can adjust the spacing between the main hook electric hoist and the auxiliary hook electric hoist according to the working conditions on site.
