Abstract
A support generally comprising a mast component, a boom component extending forwardly from the mast component, and a stabilizing component for maintaining the support in a working disposition. The support may be used in conjunction with a lifting pole for forming a hoist system. The support and hoist system may be used to support or raise and lower an object such as a chute for debris.
Claims22
A hoist system for raising and lowering an object,
- said system comprising a lifting pole and a support,
- said support comprising
- two spaced apart masts,
- two spaced apart booms, each boom being attached to and extending forwardly from a respective mast, and
- a stabilizing component for maintaining the support in a working disposition,
- said stabilizing component comprising
- a first cross beam attached to said masts,
- a second cross beam attached to said booms, and
- two counter balance members, each counter balance member being attached to and extending rearwardly from a respective mast,
- said lifting pole comprising
- an arm member, and
- a winch element attached to said arm member for playing out and reeling in a rope for the respective lowering and raising of said object,
- said arm member comprising a guide element for engaging said rope when the rope is played out or reeled in by the winch element, said guide element being spaced apart from said winch element
- releasable attachment means attaching said lifting pole to said masts, said first cross beam, said second cross beam, and said arm member being configured and disposed such that the arm member is inclined upwardly from the first cross beam and the arm member engages said second cross beam such that said lifting pole is able to raise or lower said object.
A hoist system as defined in 1 wherein each mast is pivotally attached to a respective counter balance member such that the mast is able to pivot between a working mast position and a rearward non-working mast position and wherein said support comprises a locking component for releasably locking said mast in said working mast position.
A kit for the construction of a rebuildable hoist system for lifting and lowering an object,
- said kit comprising
- a support component,
- and
- a lifting pole component,
- said support component comprising
- two masts,
- two booms, respective releasable attachment means for releasably attaching a respective boom to a respective mast so as to extend forwardly therefrom, and
- a stabilizing component for maintaining the support in a working disposition,
- said stabilizing component comprising
- a first cross beam, means for releasably attaching said first cross beam to said masts
- a second cross beam, means for releasably attaching said second cross beam to said booms,
- said first cross beam being attachable to said masts and said second cross beam being attachable to said booms such that said masts and booms are spaced apart,
- two counter balance members, and respective releasable attachment means for releasably attaching a respective counter balance member to a respective mast, each counterbalance member being attachable to a respective mast so as to extend rearwardly therefrom
- said lifting pole component being releasably connectable to said masts by a respective releasable attachment means and comprising
- an arm member,
- a winch element for playing out and reeling in a rope for the respective lowering and raising of said object, and means for releasably attaching said winch element to said arm member,
- said arm member comprising a guide element for engaging said rope when the rope is played out or reeled in by the winch element, said guide element being spaced apart from said winch element when said winch element is attached to said arm member,
- said first cross beam, said second cross beam, and said arm member being configured and being disposable such that, when said first cross beam is attached to said masts, said second beam is attached to said booms and said lifting pole component is connected to said masts, said arm member is inclined upwardly from said first beam, and the arm member engages said second cross beam such that said lifting pole is able to raise or lower said object.
A kit as defined in 12 comprising respective releasable pivot attachment means for each mast for pivotally attaching the mast to a respective counter balance member such that the mast is able to pivot between a working position and a rearward non-working position and wherein said kit comprises a locking component for each mast for releasably locking said mast in said working position.
