Claims
- 1. A pendant switch assembly for controlling a hoist for raising and lowering a load, said pendant switch assembly comprising:
a housing; a transmitter mounted to the housing for wireless transmission of control signals to a receiver mounted remotely with respect to the housing and operatively connected to a power controller of a drive of the hoist; a plurality of control elements arranged in the housing; a plurality of actuators operatively connected to the control elements in one-to-one correspondence and acted upon from outside to operate the control elements for delivering the control signals for the power controller to the transmitter; a traction member secured to the hoist and guided downwards; a receptacle secured to a lower end of the traction member, said receptacle and said housing having complementary means so that the housing can be pushed securely into the receptacle for attachment, and pulled out again for detachment; and a power source for supplying electric energy to the control elements and the transmitter.
- 2. The pendant switch assembly of claim 1, and further comprising a handle, mounted to the receptacle, for maneuvering the hoist in a direction transversely to a lifting direction.
- 3. The pendant switch assembly of claim 2, wherein the handle is configured as hollow cylinder, said traction member being guided through the handle so as to allow a displacement of the handle along the traction member.
- 4. The pendant switch assembly of claim 2, wherein the handle has one end face supported during maneuvering of the hoist upon a confronting end face of the receptacle.
- 5. The pendant switch assembly of claim 1, wherein the receptacle is configured as a downwardly open shell.
- 6. The pendant switch assembly of claim 1, wherein the receptacle is configured as handle for maneuvering the hoist by an operator.
- 7. The pendant switch assembly of claim 1, wherein the receptacle and the housing have complementary locking elements to effect a detachable connection therebetween, with the locking elements selected from the group consisting of indentation and protrusion.
- 8. The pendant switch assembly of claim 7, wherein the housing has an indentation for engagement by a protrusion of the receptacle.
- 9. The pendant switch assembly of claim 7, wherein the housing has a protrusion for engagement in an indentation of the receptacle.
- 10. The pendant switch assembly of claim 1, wherein the traction member is a cable of low flexural strength.
