Product Description

Special expansion bolts for elevators, also known as elevator geckos and expansion anchors. Dedicated to the elevator industry.

The difference with ordinary expansion bolts is:

1 The expansion tube of the elevator expansion bolt is thicker than the expansion tube wall of the ordinary expansion bolt of the same specification;

2 The expansion tube of the elevator expansion bolt is longer than the expansion tube of the ordinary expansion bolt of the same specification;

3 Several knurling grooves are added to the expansion tube of the elevator expansion bolt to increase the tensile strength;

4 The size of the screw head of the elevator expansion bolt is larger than that of the ordinary expansion bolt head;

5 Elevator expansion bolts are equipped with enlarged flat washers (GB/T96), and ordinary expansion bolts are used with ordinary flat washers (GB/T95).

This product is most suitable for the fastening joints of heavy objects such as elevators. It is made of high-quality steel, with strong shock resistance and strong force near the grip. Generally, the pressure of reinforced concrete is not less than 25MPa. It is installed in the same way as a normal expansion bolt.

Advantage

The expansion tube is made of good material to ensure effective tensile and shear resistance.

Expanded pipe size and wall thickness are strictly processed according to standard dimensions

The milling groove on the expansion tube effectively increases the friction and tensile strength

The thread has high precision and good performance with the nut.

Application industry:

Fastening joints for heavy objects such as elevators are made of high-quality steel.

Installation method:

 When using, first use the impact drill to drill a corresponding hole in the wall and the concrete foundation stone, then insert the expansion bolt and the expansion tube into the hole, then load the machine parts, and then put the large washer and the spring washer into the expansion bolt in turn, The hex nut is screwed into the tight connection and fastened to the concrete wall and the foundation stone for installation and use purposes
