Embodiment Construction

[0013] Referring to the accompanying drawings, they show the essential parts of the trolley 1 relevant to the present invention. It comprises a trolley body, of which only the load beam 2 is shown in the lateral direction of the trolley 1 . From the point of view of the invention, other body parts (not shown) in relation to the load beam 2 have no essential significance.

[0014] The trolley 1 shown in the figures also comprises a hoist mechanism 3 supported to the trolley body 2 and comprising a rope drum 4 for at least one hoisting rope (not shown), with A hoist motor 5 for driving the rope drum and a gear 6 for coupling the hoist motor 5 to the rope drum 4 .

[0015] The gear 6 has a primary side coupled to the hoist motor 5 and a secondary side coupled to the rope drum 4 , where the rope drum 4 is located parallel to the load beam 2 as seen in the vertical direction of the trolley 1 . Between the motor 5 and the load beam 2.

Abstract

A trolley (1) of a rope crane, comprising a trolley body, a transverse load beam (2) of the trolley, forming part of the trolley body, a hoisting mechanism (3) which is supported to the trolley body (2) and comprises a rope drum (4) for at least one hoisting rope, a hoisting motor (5) for driving the rope drum (4), and a gear (6) for coupling the hoisting motor (5) to the rope drum (4), whereby the gear (6) has a primary side coupled to the hoisting motor (5), and a secondary side coupled to the rope drum (4), and whereby the rope drum (4) is located, as seen in the vertical direction of the trolley (1), between the hoisting motor (5) and load beam (2) parallel to the load beam (2). The hoisting mechanism (3) is supported by a three-point support (A, B, C) to a main beam (2), whereby the first support point (A) and second support point (B) are located adjacent to the secondary side of a gear (6) so that the first support point (A) is higher on the main beam (2) and the second support point (B) is lower on the main beam (2) at a distance from the first support point (A), and whereby the third support point (C) is formed by a support of the rope drum (4) end facing away from the gear (6) to the load beam (2) at a lateral distance from the first and second support point (A, B).

Description

Background technique [0001] The present invention relates to a trolley of a rope crane comprising a trolley body, a trolley side load beam forming part of the trolley body, supported to the trolley body and comprising A hoist mechanism for a rope drum of at least one hoisting rope, a hoist motor for driving the rope drum, and a gear for coupling the hoist motor to the rope drum, wherein the gear has a The primary side of the motor and the secondary side are coupled to the rope drum, and wherein the rope drum is located parallel to the load beam between the hoist motor and the load beam as seen in the vertical direction of the trolley. [0002] In trolleys of the type described above, the hoist is usually supported to the trolley body by means of three points of support, one of which is between the hoist gear and the rope drum, i.e. on the secondary side of the hoist , the second support point is on the primary side of the trolley and hoist gear (where the output shaft of the ...
