Abstract

GUINDASTE MóVEL COM CONTRAPESO DE POSIçãO VARIáVEL. A presente invenção refere-se a um guindaste móvel que inclui uma caixa de carro apresentando membros móveis de engate de chão, uma base giratória giratoriamente conectada à caixa do carro de tal modo que a base giratória possa oscilar com relação aos membros de engate de chão, uma lança pivotavelmente montada em uma porção dianteira da base giratória, um mastro montado em sua primeira extremidade na base giratória, um engate traseiro conectado entre o mastro e uma porção traseira da base giratória, uma unidade de contrapeso móvel, pelo menos um cilindro hidráulico, e pelo menos um braço pivotavelmente conectado em uma primeira extremidade à base giratória e, em uma segunda extremidade, ao cilindro hidráulico. O braço e o cilindro hidráulico são conectados entre a base giratória e a unidade de contrapeso de tal modo que a extensão e a retração do cilindro hidráulico mudem a posição da unidade de contrapeso em comparação à base giratória. Em um método de operação, o contrapeso é posicionado à frente de um ponto diretamente abaixo do topo do mastro, quando da não existência de carga alguma em uma linha de içar carga suspensa a partir da lança, e posicionado atrás do topo do mastro, quando a linha de içar sustentar uma carga, o contrapeso móvel jamais sendo sustentado pelo chão durante as operações de operação de levantar, mover e assentar do guindaste, a não ser indiretamente pelos membros de engate de chão na caixa do carro. Em outro método, o guindaste é usado para executar uma operação de levantar, mover e assentar com uma carga onde o contrapeso móvel é movido na direção e longe da porção dianteira da base giratória com a extensão e a retração do cilindro hidráulico durante a operação de levantar, mover e assentar para ajudar a contrabalançar a carga, embora o contrapeso jamais seja sustentado pelo chão, a não ser indiretamente pelos membros de engate de chão na caixa do carro.
