Embodiment Construction

[0028] figure 1 This shows a crawler drive known from the prior art, which has been explained in detail, for example, in the background of the description.

[0029] figure 2shows a schematic side view of a crawler drive according to the invention, which has corresponding components for setting the contact surfaces of the track frame 101 in the front and rear regions of the track frame . The crawler generally has a chain 140 comprising the track pads and resting on the carriage roller 130 at the top and on the rollers 200, 200a on the ground. The rollers 200 , 200 a are held in the carriage frame 101 . According to the invention, in each case, the respective three rollers 200a are adjusted vertically downwards in the direction of the chain 140 by means of components arranged in the front and rear regions of the track frame 101, so that the The contact surfaces of the chain 140 are limited to two contact surfaces B2, B3 of equal size. If the total center of gravity 500 of ...

Abstract

The invention relates to a crawler travel gear and a crawler-mounted crane. The crawler travel gear provided with a crawler-mounted crane comprises a crawler carrier, rollers arranged at the crawler carrier and a crawler chain, with a respective adjustment mechanism provided in the front region and rear region of the crawler carrier for selectively adjusting the contact surface of the crawler carrier relative to an underlying surface.

Description

technical field [0001] The present invention relates to a crawler travel gear, in particular to a crawler travel gear of a crane equipped with a crawler, which has a crawler bracket, has a roller arranged at the crawler bracket, and has a crawler chain (crawler chain). The invention also relates to a crawler-mounted crane with a corresponding crawler travel drive. Background technique [0002] In such tracked travel transmissions, the chain, including the track pads, usually rests on top of the carriage rollers and on the ground side on the rollers, while the chain runs on a drive or idler wheel, which is set At the front and rear of the track brackets. [0003] figure 1 A cross-section along a vertical longitudinal plane of a crawler drive known from the prior art is shown. The crawler generally has a chain 14 comprising the track pads 12 and resting on top of carriage rollers 13 and on the ground on rollers 20 . The rollers 20 are held in the carriage frame 1 . The t...
