Abstract

A hoisting apparatus (10) for use at a manhole (1), comprising a supporting mast and a jib crane (14) connected at an angle to an upper end portion (16) of the supporting mast (12). The jib crane (14) has a front member (18) pointing upwardly and extending on one side of the supporting mast (12) and a rear member (20) having a rear end section (22) extending on another side of the supporting mast (12). A linking rod (24) is connecting the rear member of the jib crane (14) to the supporting mast (12). The apparatus further comprises a winch mechanism (30) mounted onto the jib crane (14) and having a cable (32) cooperating with the front member (18) of the jib crane (14) for hoisting an object from the manhole (1). In a preferred embodiment, the apparatus comprise a security fence (40) for surrounding at least partially the manhole (1) and preventing accidental entry therein, the supporting mast (12) being part of the fence.

Claims (10)

1. A hoisting apparatus for use at a manhole, comprising:
-a supporting mast;
-a jib crane connected at an angle to an upper end portion of the supporting mast, the jib crane having a front member pointing upwardly and extending on one side of the supporting mast and a rear member having a rear end section extending on another side of the supporting mast;
-a linking rod having a first end connected to said rear end section and a second end connected to the supporting mast; and -a winch mechanism mounted onto the jib crane and having a cable cooperating with the front member of the jib crane for hoisting an object from the manhole.
2. A hoisting apparatus according to claim 1, comprising a security fence for surrounding at least partially the manhole and preventing accidental entry therein, said supporting mast being part of said fence.
3. A hoisting apparatus according to claim 2, wherein said security fence is foldable and comprises fence sections hingedly connected to one another.
4. A hoisting apparatus according to claim 3, wherein said fence sections are composed of vertical posts joined together by framing members, the supporting mast being one of said vertical posts.
5. A hoisting apparatus according to claim 4, wherein said framing members are rails.
6. A hoisting apparatus according to any one of claims 1 to 5, wherein the rear member is sleeve-shaped and the front member is telescopically mounted into the rear member.
7. A hoisting apparatus according to any one of claims 1 to 6, comprising a socket connector on the rear member for removably receiving the upper end of the supporting mast.
8. A hoisting apparatus according to claim 1, comprising a base support for vertically mounting the mast.
9. A hoisting apparatus according to claim 8, wherein the base support comprises a socket connector for removably receiving a bottom end of the mast.
10. A hoisting apparatus according to any one of claims 1 to 9, comprising pins for respectively and removably connecting the first end and the second end of the linking rod to the rear member and the supporting mast.
