Loader History

TA32C and TA42C were manufactured by Nitro Nobel in Sweden

Can-Blast Inc. started 28 years ago to modify these loaders to suit the Canadian market. These loaders had an additional 'L' added to the model number to indicate they had received these modifications. Over the years a number of improvements were implemented. In 1993 Can-Blast eventually started to fabricate and assemble loaders in Canada. These models were named CB32 and CB42. The block colour was changed from red to blue and later the nylon on/off valve was replaced with a ball valve. The TA series of loaders had thinner casting flanges that where bolted together. 

RED BLOCKS: The original Nitro Nobel Red Valve Block with the sliding vane on/off air valve.

Can-Blast offered replacement parts and some modifications. Some of today's production replacement parts continue to fit these valves. Aluminum threads on mating components lead to thread galling and striping. Today's production uses stainless steel for any male threads. The sliding on/off valve has been replaced by an external mounted stainless steel ball valve.

TA5 Loader

The standard TA5 was produced by Nitro Nobel with a cartridge chamber made of brass alloy, and nickel plated. Flaps were made from bronze alloy. A modified version was produced with Stainless steel cartridge chamber and aluminum flaps. The cartridge chamber was enlarged and the flaps lengthened to accept 1-1/4" cartridges.

The Canadian made castings were thicker at the bolting flange then the TA series. The addition of tie rods through the castings provided ruggedness to the loader and solved the problem of the castings coming loose in the field.

A "Y" strainer and pilot pressure filter were added to the air supply line to offer additional protection. The Air Pressure Regulator used on the early production loader was the same as the units used on the TA5 series. These where retained to the mounting bracket by four bolts. This regulator model was discontinued by the manufacturer, and the replacement unit was retained by a large plastic nut.

To reduce stress to the piping system and components an additional support bracket was added.
