Abstract

The invention relates to a lifting and transport equipment and can be used for a cantilever supply of cargo through window or other openings of buildings. The purpose of the invention is to improve ease of operation. The traverse consists of a carrier pillar 1, to which, using an axis 2, a beam 3 is pivotally attached, on the first (cargo) arm of which, made of pivotally connected sections, is placed a load gripping body, and on the second (balancing) section, made inclined up, it is positioned to displacement counterweight 5. When lifting the carriage 6 and stand 1 are moved relative to each other, which leads to movement of the flexible elements 16 and 19. The main flexible element 19, in particular its lower section, will go from the center to the periphery of the second arm of the beam 3. But through the anvil 20 and the pawl 21, the lower portion of the main flexible element 19 is connected with the counterweight 5, which moves along the second arm to the right until it reaches an equilibrium position, after which the system is stopped by the ratchet wheel 11. The system is disengaged by means of the rollers 26,27 , 28 and an axis 23 with a dog 21. For convenience in the operation of the section of the first (cargo) shoulder, beams have the possibility of angular rotation relative to each other and fixation. 1 hp f-ly, 7 ill.

Claims (1)

Claim 1. A cantilever traverse containing a supporting beam, a stand pivotally connected to the middle part of the beam, a carriage connected to the load loop and mounted on the rack with the ability to move along it, a device for fixing the position of the carriage relative to the rack, a load-gripping body mounted on the first shoulder of the beam , a counterweight located on the second shoulder of the beam, a counterbalance fixing mechanism including a stopper, and a counterweight movement mechanism including bypass elements mounted on axles at the bottom struts and on the second shoulder of the beam, and a flexible element associated with the counterweight and enveloping the said bypass elements, characterized in that, in order to improve ease of use, the device for fixing the position of the carriage contains a ratchet mounted on the axis of the bypass element of the rack, and a dog pivotally mounted on a rack and provided with a rod mounted to interact with the second arm of the beam, the counterweight fixing mechanism is provided with blocks placed on the counterweight, horizontal a pivot axis mounted on it pivotally, a lever connected at one end to this axis, on the other end of which a roller is fixed, with a stop mounted on a counterweight, and a control cable that is connected at one end to a handle fixed to the first beam of the beam, bends around the rollers in turn and a lever unit and is fixed at the other end to a drum mounted on the second shoulder of the beam, and said stopper is fixed to said horizontal axis with the possibility of interaction with the counterweight stop, the movement mechanism being tivovesa provided ^J additional flexible element, and optional bypass elements, one of which is mounted at the top of the rack, and the other - to the axis of the main bypass element in a bottom of the rack 10 with the main flexible member with its ends fixed to the counterweight and a further flexible element encircles the mentioned bypass elements and is fixed at its ends on the carriage. . <5 2. Traverse on π. 1, characterized in that the first shoulder of the carrier beam is made of separate sections pivotally connected to one another with the possibility of rotation of these sections in a · horizontal plane with fixation of their mutual position. b ΔςΔ. 17 FIG. 4 5-5 FIG. 5
