08th October 2007 - Allentown PA - Mack Truck Museum

We went to the Mack Truck Museum prior to our tour around the factory. Photography is not allowed in the factory.

The brothers Jack and Augustus Mack started by building buses. This is No 9, built in 1901, it has a 40hp gasoline engine and a 3 speed transmission. This unit was in operation for over 25 years and travelled over a million miles.

Brockway was a separate company until they merged in 1956, so the museum also contains examples of its vehicles. This 1910 motor wagon has a Chase 3 cylinder 2 cycle air-cooled gasoline engine with fewer moving parts than any other engine in production at that time. It has a 2 speed 'planetary' transmission and was built in Homer, New York.
This is a 1923 Brockway 5½ - 6 ton truck with a Continental engine and a drayman's body. It was based at the Garden State Truck Plaza at Bloomsbury, New Jersey.
A 1919 Mack 'AB' model with a 2.5 ton chassis and shaft driven from a 4 cylinder gasoline engine. 51,613 of this model were built between 1914 and 1936.
A 1933 Mack late model 'AB' truck with a double reduction rear axle and four wheel brakes (quite an innovation for the times!)
A 1947 Brockway model 152W-14 with a 42BX Continental engine. It has a Fuller 5A93 transmission and a Timken Q100DPH rear axle.

For some odd reason this was donated by a Los Angeles restaurant owner.

Fire engines were always well looked after and tend to have survived better.

This one dates from 1918 and is built on a 5½ ton Mack AC chain-driven wood hoist dump chassis with a Mack 77hp gasoline engine. It weighs 9359lbs and has a 156in wheelbase. It was originally delivered to the Baltimore and Maryland Fire Dept on 17 October 1918.

This Mack fire apparatus is a 1927 model 'AB' combination chemical and city service hook and ladder truck from Peckville in Pennsylvania.
A little more up to date is this Mack F785T truck with a Maxidyne diesel engine and a 5-speed transmission..
Mack experimented with turbines (as many manufacturers did, but all were without success). This is one of three prototypes built in 1979 on a Mack 'WS' Cruise-Liner with an International gas turbine engine.
This is a Mack ENDT675 Maxidyne engine. It was the first series of constant horsepower high torque rise diesel engines. It produces 235hp at 2300rpm. It was the main Mack six cylinder engine from 1967 to 1980.
The eight cylinder version of the engine above, this one was produced from 1971 to 1976 and produced up to 400hp. Mack still manufacture their own engines and gearboxes although they now use Allison automatic transmissions if the customer orders an automatic. All trucks are made to order.
The factory has a number of exploded display gearboxes which will have been used for training purposes when they were current production. Parts for most models can still be supplied. This is a Mack 12-speed TRTXL1070 air operated compound transmission with twin shift levers.
  The museum is also the company's archive and has hundreds of models and thousands of photographs. This is just one of many. Mack is the iconic American truck.
However the British tommy would have found Mack trucks familiar and were in fact the ones responsible for the company mascot. During  WWI the model AC was supplied to the front and its shape reminded them of a bulldog. It was also tough and tenacious when operating in the difficult war conditions.

This is a model of a successor, the model NO supplied during WWII to tow artillery guns.

Mack is really best known for its heavy dump trucks. This is a beautiful model and captures the solid feel of the trucks.
But the chassis is very versatile. This is a cement delivery vehicle. Today most of these have the barrel facing forward..
Unknown in the UK, tractors with multiple trailers are common in the US, although two and three trailers are not legal in all states.
The scale is getting smaller but these are more widely seen.
Mack was one of the first manufacturers to deliver trucks like this. This model was built to celebrate the occasion.
The models don't have to be die cast. There are other media and plenty of craftsmen to use them. This is one of several wooden models.
The company adopted the bulldog as its mascot and every vehicle bears at least one. This is part of the sizable collection of bulldogs of all sizes and various media, including a tapestry, in the museum. The mascot on the hood has changed over the years (it now has rounded ears and a tail that is moulded against the body) as a result of litigation by people who have damaged themselves when using it as a handle. How American!
