A winch hook comprises a hook portion and a loop receiving portion adapted for receiving a loop of a winch line. At least one three-dimensional feature of the winch hook is adapted to engage at least one three-dimensional feature of a fairlead so that the hook engages the fairlead while the hook is in at least four different orientations relative to the fairlead.

In one implementation, a casket lowering system is configured to enable the lowering of a casket into a grave and includes: a casket support system configured to support the casket and temporarily suspend the casket above the grave; an electrically-actuated brake assembly coupled to the casket support system and configured to control the rate of descent of the casket support system into the grave; and a rechargeable power source electrically coupled to the electrically-actuated brake assembly and configured to provide electrical energy to the electrically-actuated brake assembly.

In one implementation, an electrically-actuated brake assembly is configured to control a rate of descent of an object to be lowered and includes: one or more rotatable surfaces coupled to the object to be lowered; one or more stationary surfaces configured to releasably engage the one or more rotatable surfaces; an electric actuator system configured to selectively disengage the one or more stationary surfaces from the one or more rotatable surfaces, thus allowing the one or more rotatable surfaces to rotate with respect to the one or more stationary surfaces and enable the object to be lowered; and a rechargeable power source electrically coupled to the electric actuator system and configured to provide electrical energy to the electric actuator system.

The present disclosure is directed to overhead door assemblies and operating systems. Disclosed herein is a drive drum that is compatible across a variety of overhead door types, including, for example, standard lift doors, vertical lift doors, and high lift doors. The drive drum of the present disclosure comprises a first cable groove section and a second cable groove section, opposite the first cable groove section, wherein at least one of the first cable groove section or the second cable groove section is in a non-linear graduated arrangement.

A hoisting system is for hoisting a vertically-suspended object. The hoisting system has a winch having a winch drum with a hoisting rope. A first part of the hoisting rope has a first diameter and a second part has a second diameter being larger than the first diameter. The first part is connected with a first end of the second part. The first part is an inner part on the winch drum when the winch drum is completely wound. The second part has a further end that is connectable to the object for hoisting the object. A ratio between the first diameter and the second diameter is such that the minimum breakable load of the first part differs less than a factor of four from the minimum breakable load of the second part, and preferably less than a factor of three. A corresponding method is disclosed.
