Abstract
A self-contained hoist device, rail device and hoist system for hoisting building materials, comprising a housing; and lifting beam extending from the housing; wherein a hoist motor for driving a winch provided with a hoisting wire and a battery pack for powering the hoist motor are arranged inside the housing, and a distal end of the hoisting wire is adapted to be attached to a fixing point above the self-contained hoist device, whereby operation of the hoist motor may cause the housing and lifting beam to be raised and lowered, respectively.
Claims16
A self-contained hoist device for hoisting building materials, comprising:
- a housing;
- a lifting beam extending from the housing;
- a winch arranged in the housing and being provided with a hoisting wire having a distal end adapted for being attached to a fixing point above the self-contained hoist device;
- a hoist motor for driving the winch;
- and
- a battery pack for powering the hoist motor,
- the self-contained hoist device characterized in that the housing is provided with a pivotally mounted pivot arm comprising one or more guides for guiding the hoisting wire, the pivot arm being adapted to be locked in a forward position by a locking mechanism to control a center of gravity of the housing, the lifting beam and an associated payload.
A rail device adapted for being secured underneath a scaffold deck element, the rail device comprising:
- a rail element extending in a longitudinal direction;
- and
- a mounting mechanism for attaching the rail device underneath a platform element of a scaffold, wherein the rail element is adapted for receiving a trolley movable in the longitudinal direction, the trolley being adapted to provide a movable fixing point.
A hoist system comprising:
- a self-contained hoist device for hoisting building materials, comprising:
- a housing;
- a lifting beam extending from the housing;
- a winch arranged in the housing and being provided with a hoisting wire having a distal end adapted for being attached to a fixing point above the self-contained hoist device;
- a hoist motor for driving the winch;
- and
- a battery pack for powering the hoist motor,
- the self-contained hoist device characterized in that the housing is provided with a pivotally mounted pivot arm comprising one or more guides for guiding the hoisting wire, the pivot arm being adapted to be locked in a forward position by a locking mechanism to control a center of gravity of the housing, the lifting beam and an associated payload;
- and
- a rail device adapted for being secured underneath a scaffold deck element, the rail device comprising:
- a rail element extending in a longitudinal direction;
- and
- a mounting mechanism for attaching the rail device underneath a platform element of a scaffold, wherein the rail element is adapted for receiving a trolley movable in the longitudinal direction, the trolley being adapted to provide a movable fixing point for the hoisting wire, whereby the self-contained hoist device and the associated payload may be moved in the longitudinal direction.
