The theft from Cobnor Activity Centre Trust sometime between January 12 and January 16 follows a similar incident at a West Sussex family adventure park this month.
Head of the activity centre Gary Palmer said the trailer was ‘an integral part’ of the centre’s activities, and cost around £9,000 new.
He said: “It’s a huge blow to the charity trust, because we actually need something like that for all our schools, to deliver our product, at the end of the day.
“The tragic thing for us was, we took steps to secure it, it’s behind a metal gate which is locked, chained and padlocked, but it seems they had a mechanism for totally shattering the lock and chain and taking it away, because we only found small fragments of the lock.”
He asked that people ‘keep a look out’ for the trailer, and report to the police anyone trying to sell one cheaply.
If the trailer is not found, the trust will buy a new one to continue its work providing fun and educational outdoor activities for school groups.
But Mr Palmer said the cost of replacing the trailer would have to include investment in securing the equipment.
“If people are targeting charities now, and don’t have as strong morals as we hoped, we’re going to have to look to beef up our security,” he said.
He added: “We’re not going to let it knock us back, we’ve got a job to do.”
Police said the Ifor Williams trailer was stolen sometime between January 12 and 16.
The same brand of trailer was stolen from Fishers Farm Adventure Park in Wisborough Green near Horsham at around midnight on January 3.
Thieves cut through and removed a padlock on a gate before driving off with the 12-foot trailer, but were prevented from taking more equipment after a staff member chased after them.
A spokesperson for police said the two incidents have not been formally linked.
