The hoister comprises a main girder (10), a movable pulley block (3), a fixed pulley block (5) and a hoister (1).

The present invention relates to an attachment means and an apparatus for lifting heavy loads P by means of a lifting means H in the form of a sling or strap.

A lifting means is attached to the grommet.

The attachment assembly (15, 17) comprising a lifting means (31).

The hoisting means is equipped with a clamping mechanism (19).

This ensures that no compressive loads are applied to the hoist means (13) which might otherwise cause bending or bowing of the hoist means (13).

The lift platform is connected to lifting means enabling a user to vary a height of the lift platform with respect to a ground surface.

The lifting device of the buffer device comprises a first lifting means (13) for moving the input end of the buffer device up and down and a second lifting means (14) for moving the output end of the buffer device up and down.

either be fitted with attachments for lifting gear, or

The device is characterized in that the drive means of the traveling carriage, the flask lifting means, and the punch head lifting means are disposed above the sand mold with the poured flask.

The other end of the pulling device (5) is in turn designed to be connected to the lifting means (3) of the lifting device (2).

Preferably, a lifting means such as hydraulic lifting cylinder (22) constitutes a fourth element.

According to the invention, the support means (8) forms, at the same time, means for lifting the jaw model (1).

The elevating means (35, 36) may be operated by a single lever (39).

(F) - average number of lifts per minute over a 15 minute period.
