A selection of mechanical and non-mechanical aids for transporting Poles

Pole timber grabs are for the use of staff engaged in the handling of wood poles at pole stacks and at locations where poles are to be erected or recovered. Poles can be carried over short distances with the aid of the hand-type timber grabs.

CREOSOTE CONTAMINATION
By using pole timber grabs for handling and carrying poles the contamination of clothing is reduced considerably and staff who use barrier cream on their hands will be adequately protected from creosote contamination.

HAND TYPE

This hand type appliance (Fig 1) has a safe working load of 200Kg and consists of a pair of mild-steel scissor-action timber hooks attached to links and coupled via a swivel to the centre of a wooden carrying handle.

Pole Timber Grab (Manual lift)

CRANE TYPE

DESCRIPTION
This appliance has a safe working load of 500Kg and consists of a pair of heavy-duty scissor-action jaws coupled via links to a lifting shackle. A curved surface plate is welded to each of the jaws and eight pointed studs are riveted to each curved plate to prevent poles slipping during lifting operations. The shackle can be readily slipped over the hook of a crane, gantry or similar lifting device.

AUTOMATIC LOCKING MECHANISM
The appliance is equipped with an automatic locking-and-release mechanism situated between the upper links of the scissors. A key projects from the underside of the locking mechanism and this key engages with a slotted link situated between the lower leaves of the scissors. As the curved jaws are opened to their fullest extent the scissor action compresses the locking mechanism, causing the projecting key to turn through 90⁰ after it has passed through the slotted link. In this condition the jaws are locked in the open position.

With the jaws locked in the open position the appliance is raised (by the crane or other lifting device) and then lowered on to the pole to be lifted. The weight of the appliance resting on the pole again compresses the locking mechanism, causing the projecting key to turn through 90⁰ so as to bring the key and the slotted link into alignment. Raising the timber grab will then close the jaws so that the pole can be lifted.

USE WITH CRANES AND FORK LIFT TRUCKS
When the device is to be used with Cranes, Self-Mobile, a short sling chain should be used between the grab and the load hooks situated on the underside of the crane jib. Similarly, when the device is to be used with Trucks, Fork Lift, equipped with a jib-crane attachment, a short sling chain should be used between the grab and the load hook on the crane attachment. The short sling chain will enable the grab to be lowered sufficiently for it to pick up poles from ground level, and will also prevent the rigid arm of the jibs interfering with the free movement of the scissor action of the timber grab.
