- Crate tong
- Cylinder tong
- Die lifting tong
- Gear tong
- Ice tong
- Ingot tongs

- Paper roll tong
- Pipe tong
- Slab tong
- Tube tong
Bushman Equipment, Inc. lifting tongs are designed and manufactured according to the latest revisions of ASME Specifications B30.20 and BTH-1, Design of Below-the-Hook Lifting Devices.
There are three basic tong configurations and application concepts:
Supporting tongs are for single-size objects that have support clearance underneath, such as boxes, crates, bins and containers. The lifting feet of the tong support the load and maintain it on a horizontal lifting plane.
Gripping tongs are for materials such as ingots, rolls, tubes, pipes and other round or cylindrical objects. The tong extends beyond and below the center of the load to provide additional support. The diameter of the load may vary by approximately 25%, but the variation in length is generally unlimited.
Pressure tongs grip the vertical sides of slabs, bales, boxes, billets and other flat or round objects. Pads on pressure tongs provide surface friction or penetration of the load to maintain a safe hold during handling. Pads can be provided with rubber, belting, pins, hardened points, serrated bits and other materials.
Automatic Latching Device for Bushman Equipment, Inc. Lifting Tong Grabs
Each tong is equipped with the Bushman Equipment, Inc. automatic latching device that provides safe and reliable operation of the clamping mechanism. To operate the latch:
- With the lift open, position the tong over the load.
- Lower the tong onto the load. With the lifting tong resting on the load, and hoist tension released, the latch automatically disengages from the locked open position.
- Raise the hoist to allow the tong pads to close onto load. Then lift and move the load to the desired location.
To release the load, lower the tong grab and place the load on the ground to relieve tension. The latch will automatically lock the tong in the open position. Then raise the hoist to remove the tong.
