The invention is particularly applicable to cranes, hoists and the like. Working equipment in which the load sizes often change. Fig. 1

Description

Title of the invention Crane hook

Field of application of the invention

The invention is applicable to hoists, cranes and the like · Work tools with frequently changing load sizes.

Characteristic of the known technical solutions Crane hooks are known which are designed as single hooks for small loads and as double hooks for medium and heavy loads · These boom frames are adapted to the load conditions in crane operation and fulfill all requirements with constantly recurring identical inserts. · The double hooks have for the Use of cranes with frequently changing load cases has the disadvantage that, when a load is unilaterally hooked in the hook mouth the hook hook with the double hook is obliquely, whereby a secure IPührung hook hook is no longer guaranteed · Disadvantage is still the existing unbalanced load of the double hook ·

According to SU-US 903 279 a solution is known in which a suspension in the form of a bore is arranged at the lower end of the double hook shank.

Furthermore, a hoist is known, at the double hook at the lower end of a shackle is arranged ·

In the solutions the disadvantage attaches to the fact that for the load stop on the double hook or on the additionally arranged suspension different slings are required · - 2 -

Object of the invention

The invention has set itself the goal of creating a load hook on the loads can be double or simply posted »without causing the stop means must be changed and with a secure guidance of the hook bottle is guaranteed

DISCLOSURE OF THE INVENTION The invention has for its object to develop a load hook for both double and easy striking of loads, with which an oblique hanging of the hook block is avoided in simple striking loads and trained for this load case EinhängemSkeitkeit as for the double Stop is arranged.

According to the invention the object is achieved in that at the lower end of the double hook in its axis of symmetry or offset to a single hook is arranged · The plane of the hook mouth of the single hook is in the plane of the hook mouth of the double hook or at an angle to it ·

embodiment

In the drawing expedient forms of realization of the invention are shown, namely:

1 shows a crane hook with double hooks and single hooks arranged on the same shank FIG. 2 shows a crane hook with a single hook arranged offset to the shank of the double hook

Below the double hook 1 is at the lower end of the hook shank 2 in its axis of symmetry 3 a simple

The planes of the hook mouth 5 of the single hook 4 and the planes of the hook mouth 6 of the double hook 1 expediently coincide, but can also be arranged at an arbitrary angle to one another · Zn Pig · 2 is a crane hook, in which the single hook 4 is arranged offset to the shaft of the double hook 1.

The embodiment according to the invention has the advantage that, depending on the load size, either the double hook or the single hook can be used with the same slinging means.
