The cooling and/or heating of drive and/or transmission units of construction machines and similar equipment is disclosed. A temperature control device can cool and/or heat such drive and/or transmission units. The temperature control device can include a heat exchanger module having a liquid jacket through which flow is possible. The heat exchanger module can form a ring body for fitting in a sandwich-like manner between two transmission and/or drive sections. The ring body can have a central through-cutout for a drive element to pass through and can have on each opposite end face a connection flange for precision-fit end-face connection to the two transmission and/or drive sections.

Temperature control device for drive and/or transmission units such as tunnel borer transmissions

The present invention relates to a hoisting winch assembly comprising at least two preferably axially parallel drums spaced from each other axially, which can be driven in synchronism with each other by two motors via a transmission assembly. The invention furthermore relates to a crane, in particular a gantry and/or container crane, with such hoisting winch assembly. According to the invention, the transmission assembly has at least two separate gear trains, so that each motor is in drive connection with one drum each via a separate gear train. As compared to a common transmission to which both motors are connected, the separate gear trains can be configured significantly lighter and smaller, as no longer the power of both motors added up, but only the power of one motor must be transmitted. Nevertheless, high hoisting powers can be provided on the whole, as each motor must drive only one drum.

Hoisting winch assembly

The present invention relates to a winch, in particular a luffing winch, with a winch drum, at least one main drive driving the transmission input shaft, and at least one emergency drive driving the transmission input shaft in case of emergency, wherein at least one emergency drive can be coupled to the driven wheel of the transmission input shaft as required via at least one intermediate gear. The present invention furthermore is directed to a construction machine or a lifting device with at least one such winch.
